Let's Go Back to Nature: Self-Administered Test (True or False, 25 Items)
Dr Abe V Rotor

1. "Going back to nature” means we have to live the lives of our ancestors and renounce our modern living.

2. We can actually transfer genetic materials from one organism to another irrespective of species or class or sub kingdom by means of genetic engineering, resulting in the formation of what we call as GMO.

3. Genetic engineering actually started with Gregor Mendel, the father of the science of genetics and heredity some two hundred years ago.

4. There is no question about a human clone of not having a soul because, the soul of the parents transcend to offspring which is the clone.

5. We live under different ages all at a given time - atomic age, computer age, age of genetic engineering, and space age – all rolled into what scientists called the age of postmodernism.

6. “Tailor the land to the crop, and not the other way around,” is a cardinal rule of "treaty between man and nature."

7. Man is a recent creature on Earth. If the 5 billion years of the earth’s existence is compared to a calendar (365 days), man came into this world only on the eve of December 30. Man is only one-day old on earth.

8. “Our lives are being run and outrun by science and technology.” This statement is generally true.

9. "Universities without walls" or "distance education" will enable mass education to the grassroots. It will break the cartel or control by elite universities and colleges.

10. Toxic metals abound on land, sea and air – from kangkong to tuna to fowls – unless we control the emission and spread of these toxic metals.

11. Going back to nature is to become a strict vegetarian – giving up animal products. Unless we do this we can’t truly say we have gone back to nature.

12. “Ecological paradigm of salvation” means “we express our love and care to people by protecting nature.” Plant a tree, for example, is reverence to nature and therefore to the Creator; kill a tree and you commit a sin – more so it caused flood and erosion leading to death and destruction.

13. Support and actively participate in movements such as Clean Air Act, Piso sa Pasig, Clean and Green, Green Revolution, Carless Day, Car pooling, Biofuel, Saving Endangered Species, Greenpeace.

14. Convert deserts into woodlands and pasture; empty shorelines into resorts, given the tremendous resources to accomplish such gargantuan task.

15. Petrodollar is the life of the world economy – so that we support the idea there there is plenty of oil yet to be discovered. There should be no letup in tapping these reserves.

16. We should implement stricter laws such as: absolutely no logging (total log ban); impound all smoke belching vehicles; no conversion of agricultural to industrial lands; no hunting of wild animals; and the like.

17. Even without the human species, Planet Earth will continue to “go round” so to speak in the same way as it did in the last 5 billion years – and perhaps go on for another 5 billion years. We just don’t know what will be the kind of dominant species after us.

18. Homesite for the golden years is feasible in the rural as well as in the urban areas; it can be modified according to area, design and structure – but not purpose.

19. It is good to go back to classics without aristocracy, spirituality without religious dogmatism; philosophy without ideological bias; realism without barbarism – to have a better view of life, and a firmer basis of our decision and faith.

20. Science and technology has imprisoned us in many ways – that is why we are not truly happy. We need a direction – a definition of life’s meaning. Logotherapy is as relevant as in a situation where we are kept helpless in a prison camp.

21. Science and technology has actually eliminated the scourge of the human race – disease, poverty and ignorance. Actually we are only begging for more benefits discreetly.

22. Today it takes weeks for man to make diamonds in special oven chambers the size of a washing machine, when it would take nature thousands of years to make one.

23. Reports have been verified of the presence of bromate in sugar, sulfite in wheat flour, nitrate in meat, human hormone in milk.

24. Alternative vegetables are not to be recommended because we have barely studied them unlike conventional vegetables.

25. Homeostasis means dynamic balance – Nature’s way of renewal, renaissance, seeking stability as continuing goal.

Assignment: Handwritten on regular bond
Questions: 
1. What is the lesson of this story?
2. Outline the life cycle of the preying mantis.
3.. What other insects or their relatives which are made into pets?

"Friendship is made more meaningful when one recognizes the right of the other to be free over and above mutual care and respect." - AVR

A green creature surreptitiously stalked behind a leaf. It was either hiding or lurking. I could have missed this master of camouflage if it did not stare, large off-tangent eyes on the guard, 180 degrees on any plane.

That was how Ichabod, the green mantis, came into my life. I plucked him from his perch and brought him to my room. Most of the time Ike stayed on the jamb, waiting for some kind of manna - flies and mosquitoes falling from head-on collision with the glass pane. Or he would snatch other insects that blundered within his reach. Feeding on these pests spared me of annoyance.

I learned to recognize a symbiosis of two friends. I caught young hoppers for my friend. It was the green lymph which he relished most. That gave him a change in diet. I took him for rides on my palm and shoulder and helped him survey for insects which he would lunge at and devour. In the sala he frequented areas where nocturnal insects hovered. Ike was contented with this kind of life, so I thought.

One afternoon I was surprised to find my friend hanging, dry and weightless like an empty sack. He must have paid for his own goriness, I concluded. Ike is a voracious predator, devouring creatures even bigger than his size. His front legs have sharp, long spines which instantly drive fast and deep like saber or fang, and a victim would simply writhe and struggle briefly, while its head is severed by vise-strong mandibles.

I began to feel sorry for Ike. I reached for him to give my last respect to a good friend.

But Ike simply hung his old clothes. A little farther I found him a metamorphosed new creature seemingly laughing at my ignorance. Ike had entered into the final and mature stage of his life, now with full grown wings, and a powerful body, three inches long. Ignorance and curiosity led me to the library.

Mantids or mantises are related to grasshoppers, locusts, crickets and cockroaches. They are the only carnivorous species under Order Orthoptera (now Mantodea). They are called praying mantises because of their kneeling position, or preying mantises for their predatory habit. They are more popular by their latter name, although in many countries they are called mule killers, soothsayers or devil horses, which of course, are not to be taken literally.

One of the common beliefs about the mantids is that they spit into the eye causing excruciating pain or possibly blindness. This is not true. A species of walking stick, another relative has been observed to be the culprit. No, not my friend.

Indeed the mantids are ferocious when it comes to preying. And when they eat on destructive insects, farmers like them. Their devouring instinct is carried on wherever they go and whatever they do - even in lovemaking! The female devours her mate during mating or after he has wooed her. Scientists say that on the occipital portion of the head of the male lies an inhibitor, a mass of nerves called ganglion. When this is gnawed away, the sperms are discharged in no time, terminating the marital act and insuring egg fertilization. Devouring the remaining part of the body afterward is believed to be just a matter of satisfying appetite.

I knew then what would happen to Ike when he gets a mate. Days went on and he became more lonely. He had reached full “mantidhood”. So I decided to give him a bride but one that was petite and thus eliminate a dreaded fate. But Ike was indifferent, and did not show the slightest affection. Instead, he squeezed his potential bride between his raptorial forelegs until she was killed. I felt ashamed to realize that what I was doing is a violation of a treaty in friendship.

So I had to make a decision. One morning I took Ike for a ride, opened the window, drew the curtains apart, and put him there a leap away from the free world. As I gently stroked his back he gave a long meaningful look. I just smiled back and walked away.

When I returned my friend was gone. As I stared at his old clothes the morning breeze brought in a nostalgic feeling that was to remind me for life a true meaning of friendship.

A legacy born out of a brief accidental relationship of man and insect shares a lesson that friendship   is made more meaningful when one recognizes the right of the other to be free over and above mutual care and respect. ~

Make Your Dog Happy

      “Make these dogs happy,” I told a group of schoolchildren who were taking art lessons from me. I gave each of them a copy of a trace drawing of a pair of dogs. The dogs looked sad, docile and there is something pathetic about them.

      With pastel coloring instrument they accepted the assignment.  In their young minds I saw their pets at home.  As I studied the expressions on their faces, matched with their actions I noticed they were not only coloring their pets, they were virtually “caring for their pets.”

Jamby, a Japanese Spitz, roams freely at home. 

      And what do you think they did with these animals?  How kind are these children to them?   How good are they as masters or friends – as pets? These are the things I gathered from their drawings.

1.   Unchain the dogs – A young participant made a drawing of a chain being sawed off in order to free the dogs. Truly there is nothing more important than freedom, even for an animal. This is also true with animals. Aren't zoos today moved to bigger spaces where the habitats of the animals are simulated?  In the African Safari tourists are taken out, caged in their vehicles, while the animals roam free.

2.  Build a doghouse – Keep them from heat and cold.  Give them a sense of security and comfort.  Give the doghouse some art and a bit of aesthetic sense. The house is a status symbol but its functional features are foremost.
   
3.  Provide a shade – A tree beside the doghouse is a magnificent scene: 
a bird’s nest atop, bridling and parent singing at feeding time, ripe fruits hang, a kite is stuck up on a branch, a boy climbs to retrieve it, leaves fall and form a litter on which the dogs lay.  These and many more, which the children drew, revive the childhood to every viewer of their art works.

4.  Give them bone – If there is anything a dog is associated with, it is a big bone.  Aesop saw it fitting for a fable, a lesson about greed.  For the dog however, it is a form of security, as well as a plaything. Be sure you give your pet food, fresh water and proper nutrition. Do not overfeed them.

5.  Play with them, give a plaything – I found out that many of my pupils drew themselves beside or playing with their pets.  Others drew cats and mice playing with their dogs.  Playing is universal among animals, tame or in the wild.  Others raced with them on the meadow.

6.  Groom them – Regularly bathe and comb them. Several drawings showed the dogs in attire, one in a circus outfit, another in casual wear, one eating on Chinaware. This is not rare because we often think of animal as human beings.  Read “Animal Farm” by George Orwell.  Or see the movie, “Babe.”  Aesop’s fables are about animals that think like human beings – or it could be the other way around, as Aesop wanted to drive a point, quite often a painful lesson.  Aesop was silenced because he was unwittingly hurting people with his fable.  

7.  Teach them tricks and discipline – A ball, a stick, an electronic gadget to open or close the doghouse, are among the things the young participants included in their drawings. There’s a saying, “You can’t teach an old dog new tricks.”  But children always see their pets young. This means they are growing up together, and sharing new tricks.

8.  Vaccinate your dog – A participant drew a veterinarian administering     an anti-rabies shot on his young pet.  Precaution is always important, because catching rabies is dangerous.

      Who are these children mirrored by their drawings?  And who will they be through the keyhole of their imagination? How we regard our pets is what we are and become. 

Last days of Nikko, a Dobberman, 
our guard for 15 years.

      “A starving dog at his master’s gate predicts the ruin of the state,” thus William Blake in “Auguries of Innocence” tells us.  I, for one, would gladly meet with confidence and ease the master of a contented and happy dog. 

History of the Dog

      Forty million years ago there were small, long tailed tree-climbing creatures called “Miacids”, according to David Lambert. These fierce animals prowled the forest; what we now know as North America.  From the Miacids came three groups of descendants: Amphicyon (wolf-sized bears), Borophygus (hyaena-like creatures), and
Tomarctus, (the long-legged dogs).  It is the last group which led to all the living breeds of domesticated dogs and to their wild relatives, foxes and wolves.  

      No one can exactly know how dogs evolved but fossils show that dogs were helping human hunters as far back as 10,000 years ago. This means that the dog has been a friend to man from the time of the Middle Stone Age.

      Not many people know how extensive is the dog, a man’s best friend.  Perhaps the reason is that as people move to live in the cities, the original man-dog relationship evolved into mere friendship. 

      But through the years, dogs have remained helpful and loyal to man in the following ways:

1.  Helpful Dogs  - Certain dogs are so intelligent and trustworthy they can be trained to guide blind people around obstacles and through the city streets.  The German Shepherd, also known as Police Dog has a trained nose to detect explosives and drugs.  The Russian terrier Laika, was the first animal in space.

2.  Working Dogs – Shepherd dogs guard and round up flocks and herds. These are the Collie, German Shepherd, Sheepdog, Maremma, Kelpie, Puli and Corgi.

3.  Traveling Dogs – The best known of these dogs is the St. Bernard.  There is a stuffed St. Bernard dog at the UST Museum of Arts and Sciences, a keg tied around its neck.  As long ago as the 17th century the monks of St. Bernard de Menthon kept and bred dogs to guide and rescue travelers from the snowdrift of the Swiss Alps. These dogs were the ancestors of the St. Bernard we know today. Other mountain dogs are the Bernese, Pyrenean and the Newfoundland.  They pull heavy snow sleds over great distances, herd reindeers, or just be plain good guards and guides.

4.  Guard Dogs – Guard dogs must be loyal, obedient, courageous and strong.  Take the case of the Doberman.  In the late 19th century a tax collector, Louis Dobermann, used local dogs to breed an animal that would guard the money he carried.  The result was the Doberman Pinscher, a fine dog that is proud, fast and fearless.  Two German dogs, the Rottweiler and the Boxer, and the Tibetan Mastiff are equally fearsome watchdogs.   

5.  War Dogs – Being carnivores dogs have the instinct for hunting and killing, which means that they can be trained to fight.  Even in ancient times dogs were trained to attack enemies. Ten thousands dogs served with the Allied Forces in World War II. War dogs include Bull Terriers, Bulldogs, and the Molossus, a dog trained by the Greeks to attack the Persians.

6.  Game Dogs – Sporting dogs are the Springer, Spaniel, Setter, Retriever, and Hound. Each breed has a special way of hunting. Spaniels flush out game from grass and shrubs, while the Pointer, upon finding a game bird, stands still with its head, body and tail pointed like an arrow towards the quarry. Man first made friends with the dog through hunting. Both enjoy the prize of the game.

7.  Detective Dogs – Dogs have very sensitive noses.  The scent hound can track its prey by its scent for hours and over a long distance.  The Bloodhound is the oldest of all scent sensitive hounds. Other detective dogs are the Foxhound, Basset Hound and Dachshund.

The Danger of Rabies

      The great biologist, Loius Pasteur, succeeded in saving a boy bitten by a rabid dog. From here the world found relief in combating the disease through immunization.  Today, anti-rabies vaccines are available in big drugstores.

      But rabies is still one of the most dangerous killers and there is no cure to it.  That is why immunization is necessary.  Have your dogs vaccinated with anti-rabies.  When a dog that has not been vaccinated bites, the best way is to have the victim treated immediately with anti-rabies serum.

      Dog meat eaters beware.  The hidden killer lies in the dog meat.  The rabies virus is not readily killed by heat.  Besides it is a common practice to eat dog meat medium rare (kilawin) with the brain of the animal mixed in with the rest of the ingredients.  Many do not know that the virus attacks the brain, therein it multiplies.

Dog Attack

      In the US alone there are thousands of reported attacks by dogs, some leading to death.  When my family had just transferred to the subdivision we are living in now, our dogs chased and bit a boy in the neighborhood. It was only a bruise but it was not an auspicious start for us as new residents.

      Here are tips for avoiding dog attacks. When there is a menacing dog around do not run.  Stay calm and walk away slowly.  A stick or anything to fend off the dog can help.  Avoid walking through a pack of dogs.  Know where the doghouse in the neighborhood is and try not to get near it.  Don’t just saunter through someone’s gate.  Call first or use the doorbell.

      But, of course, the best way is to act like a boy scout by always staying alert, not only for dogs but any form of danger.

The Pet Dog Today

       When you hear the word, askal, it means mongrel, although in common parlance is “street” or kalye dog. Mongrels are dogs whose parents are of mixed breeds.  Although coming from a mélange of breeds, they sometimes tend to exhibit a dominant bloodline. Mongrels may intentionally be crossbred to pure breeds to improve the breed, with satisfactory results. Two good things about mongrels are that they are resistant to local diseases, and are less choosy with their food. 

       It is also the mongrel that ordinary people raise as pets and source of food at the same time. When grown and fattened they are slaughtered. Dogs are sold for meat in many countries, but Americans and Europeans, who keep dogs like members of the family, strongly detest this practice.  In the early nineties Congress received thousands letters protesting the killing and eating of dogs. Among the appealing institutions is the Royal Society for the Prevention of Cruelty to Animals (RSPCA). Now and then we read news story about jeeploads of dogs intercepted on the way to the slaughterhouse. If we have any knowledge on this illegal act it is best to call the nearest police station.

Impact of the Art Workshop

      The art workshop for children in which I used the dog as an exercise to demonstrate love for animals may be a simple way of changing attitudes and developing values. Children are known to be very effective in carrying out the multiplier effect of a lesson and we hope that they will carry this as they grow.

      “Make these dogs happy,” could mean a thousand dogs in the future, and a thousand enlightened children who follow the footsteps of those who unchained the dog, built a doghouse, gave a bone and, altogether, made the world a kinder one for dogs.

--------------------------
There's no substitute to substance. Keep abreast. Elevate the level of consciousness. Remember "poor minds talk about people, average minds about events, great minds ideas." AVR
--------------------------
You'll freeze on stage trembling and mumbling, and mental block could be the next thing to happen. It's a crucible to one who is not prepared to go up the stage and say something before the microphone, and before uttering a single word, the audience is already anticipating what he is going to say. And they are already making judgment on the impression he is creating.

Philippine President Ferdinand E Marcos had a special gift as a great speaker - highly intelligent, persuasive and charismatic.  His extemporaneous speeches impressed members of the US joint congress, the UN Security Council, local and regional conferences, notwithstanding.

Time stops. How you wish your role is over and go back to your seat. Don't be a escapist to a challenge, responsibility, and a chance to be heard. To be appreciated and recognized.

People who are good in public speaking do it everyday, so to speak. It is as natural as ergonomics. Green thumb. Like driving a car for years. Or like a veteran teacher.

Well, for all we know "we are on stage talking" most of the time in our lives. Shakespeare said, "The world's a stage." The stage is everywhere - before the dining table with the family, in meeting relatives after years of absence. How many times have you sat beside the hearth among friends and acquaintances?

It's a good advice. In public speaking you should be natural and at ease. Know your subject as you know your audience. And yourself as a public speaker.

In public speaking, as in any form of communication, there are five basic elements, often expressed as "who is saying what to whom using what medium with what effects? "Public speaking can be a powerful tool to use for purposes such as motivation, influence, persuasion, informing, translation, or simply entertaining.

Here are some tips to good public speaking.

1. Prepare an outline of your main points and put them on index cards or a sheet of paper. Don't write out your whole speech and read it.

2. Write your own introduction. Don't rely on the person who will introduce you to come up with a good introduction. Send it before the event to the person who will introduce you.

3. Dress comfortably, neither under and over dressed. Know the dress code and motif ahead of time. Remember grooming is visual and psychological communication.

4. Check out the hall and have a feel of it before the occasion. Arrive a little early. See immediately your host or organizer. Check the needed equipment and materials. Confer with the technicians if you use PowerPoint or present a Documentary. 

5. Get to know your audience. As audience members arrive, introduce yourself and chat with them. It will reduce your nervousness later.


6. Reminder: grammar, diction, modulation, breathe, pacing . Watch out for mannerism. Be aware of the time allocated to you. Don't stammer. Fight off uhs, ahs, hmms, and long pauses.

7. Remember that the audience is on your side. They came to hear what you have to say.
Unless you are in the thick of controversy. Or selling something new - idea or hardware. Even then, people should not be there - or you won't be there, either - if there is no planned purpose of meeting together, and you as speaker.

8. Practice makes perfect. With practice, you can become a confident, polished speaker. Take advantage of opportunities to hone your skills.

9. Research on your topic, enrich it through interview and case studies. There's no substitute to substance. Keep abreast. Elevate level of consciousness. Remember "poor minds talk about people, average minds about events, great minds ideas."

10. Be courteous and humble, spice your talk with wit and humor. Always maintain dignity and values, even in informal gatherings.

Next time you are invited to talk, prepare for it well. Do the dry run several times like editing an article for publication. This time it's not for the eyes only, but all the senses are involved - specially Common Sense. ~

Demosthenes achieves an astonishing intensity, variety, and freshness of emotional expression. He never lets his audience anticipate what he will say next. No one creates periodic sentences longer or more complex, or so skillfully suspends the conclusion of a thought. No one has a better instinct for when to vary periodic structure with simpler sentences, or when to break off with a single word. No one better handles the thrust and parry of rhetorical questions and answers, sarcastic asides to and about his opponent, and sudden exclamations. No one can shift his tone so swiftly or with such effect. From a Lecture, Greek Prose Style

NOTE: One thing about Demosthenes my dad taught me when I was a kid is how this great Greek orator fought problems in voice and diction, specially with pronunciation, "R" specially, which is a common problem with children and youth today. Demosthenes would put pebbles into his mouth, and face the sea as his audience, a practice that also increased tremendously the volume and projection of his voice that reverberated in the Senate hall like there was microphone in his time.*

*Try this with caution. Accidental swallowing of the pebbles may cause asphyxiation.

Comment: Thanks sir, for posting it in the blog, as a student we need those tips not just for now, but for a lifetime, especially when we have our jobs. And for us to know how to express ourselves and for us to be able to socialize confidently. I will try to follow these steps written in the blog, for me to learn and to be good in speaking. - Chiara Alyssa Cochico

I wonder why herons hide their nest.

Dr Abe V Rotor 

Herons are migratory birds flying over great distance from their abode. Their arrival by
the flock signals the start of the monsoon season. They frequent ricefields feeding on frogs,
 insects, and other living organisms. Their association with carabaos and cattle creates a
romantic ambiance that has inspired artists to paint and write stories about these enigmatic creatures.

Why do herons hide their nest?
Where on earth is their home?
I stalked through the thorny test
Where the white feathered roam -

Hushing away the unseen,
Deity, the fanged or quagmire;
I became part of the scene,
A drama of life to admire.

As the birds basked in the noon sun
In regal poise and dainty movement,
I moved for the kill, a lens on hand
To freeze the precious moment.

But lo! A loud crack filled the air
Driving the birds away from their rest;
My story now untold - but who would care?
Wonder why herons hide their nest.

1. How can the sun reach the hadal depth,
Where the world is cold, where love is dearth?
Hasn't someone a bit of sun long kept?

2. 
Beauty seen once may break many hearts,
That heal soon enough as the image departs.


3. Come, come and save the hearth.
A tenth of our brain is all we use
In a lifetime – the rest we save;
Yet spurs us to reach the stars,
Or drives us fast to our grave.

4. A vessel holds water to the brim,
Unless it bears a crack at its rim;
As men wish power in their dream
Even if they have lost their steam.

Baby Mackie at home

5. Brick wall, brick roof, brick stair,
Glisten in the rain, dull in the summer air.

6. Archetypes feed the memory
As the past is here to stay.
We see the child of yesterday
Through a window today.


7. Ephemeral and fleeting are the days of our lives,
When we do not watch the sun set and rise.

8. Convenience is like wings
Gliding on the wind’s will.
It is also not taking off
Until the wind is still.

9. From respite in summer fallow
The fields start a season anew.

10. He finds reason for living
Who sees a new beginning.~

Wild sunflower, Tithonia diversifolia may have been introduced into the Philippines from Mexico by the Spaniards.

 Who would have thought that those shrubs with bright yellow flowers growing by the roadsides or wastelands make excellent organic fertilizer?
entomology 
      Wild sunflower, Tithonia diversifolia, has been found to contain high levels of nitrogen content, exceeding nearly six percent. It has enzymes that hasten decomposition and cut down composting time from three months to just a few weeks. This is why it is an excellent additive for composting rice hay and other farm wastes, materials which have low nitrogen contents, decomposition.

      Sunflower added to compost piles builds heat and sustains it at a high level of over 55 degrees Celsius. At this temperature weed seeds and harmful microorganisms are killed, including those that cause acidic reactions.  Acidic soil “locks up” nutrients that are otherwise made available for plant use.

      With the addition of chopped sunflower into the compost pile, its pH value remains at seven to eight pH (neutral to slightly alkaline), throughout the decomposition period.  Under this condition nitrogenous materials are immediately mineralized into ammonium nitrogen (NH4N+) and nitrate (NO3) which are directly absorbed by the plants.

      These are highlights of a graduate research study by Prof. Luisito Evangelista at the University of Santo Tomas for a masteral degree in biological science.  “Accelerated composting is the key to successful production of on-farm organic fertilizer, specially in areas where sunflower abounds,” Evangelista claims. 

      In areas where the inoculant is not available, sunflower is an alternative to Trichoderma a cellulose-acting fungus strain developed by Dr. Virginia C. Cuevas of the Institute of Biological Sciences at UPLB.  

      When the sunflower-activated compost was used on Red Creole onions, yield increased by as much as 20 percent, while the physical quality of the bulbs improved.  Other than being bigger, the bulbs are brighter, heavier and more uniform in size. Their necks are well closed, reducing the danger of rotting during storage.

      Here are ways to make sunflower compost:

1.  Prepare a well-drained area, half shaded if possible.  Here, construct a compost pile of 2 x 4 meters in dimension, and breast high when compacted.

2.  Prepare the raw compost materials by chopping the rice straw and green wild sunflower separately.  The ratio by weight of sunflower to rice hay is 3:1.  Ready chicken droppings (or animal manure) and topsoil from the farm.

3.  Pile these materials in the following arrangement: the rice hay makes the first layer, 20 cm thick.  On top of layers are the chopped sunflower, followed by manure and soil.

4.  Make a second set of layers on top of the first, compacting the pile as the process is repeated. The pile should not be higher than 1.5 meters for convenience in watering and turning over.

5. Vertically insert aeration tubes made of bamboo poles onto the pile 50 cm apart. The tubes are made by partly opening the nodes, outside and inside to allow air to enter and for heat to rise.

6.     Monitor temperature with a thermometer inserted through the tubes.
Heat is expected to increase immediately, reaching its peak within two weeks before it declining.

7.  Maintain watering sufficient to keep moisture content at 60 to 70 percent.  Use plastic or burlap sacks to cover the pile, protect it from rain, and help conserve the heat generated.

8.  As decomposition progresses, the pile will shrink and the temperature will soon equal that of the surroundings. After three to four weeks, the compost is “ripe” for harvesting.  To facilitate the process, turn the pile once or twice  before reaping.
    
To know if the compost can now be used, here are the indicators:
· Make sure there is no foul odor emitting from the pile.
· The temperature must have dropped and is about the same as that of the surrounding area.
· The original substrates are no longer recognizable.
· The color is dark, loamy and soft to the touch.

     Composting is a bio-oxidative process, which results in the production of a stable organic product, contributing directly to soil conditioning and fertility. In many books, it is called mineralization, or the breaking down of organic compounds into their elemental forms and as they settle down in the soil. This process is particularly true with nitrogen. This is nature’s way of recycling chemical compounds, from organic to inorganic form, and vice versa.

      Composting rice hay alone is not advisable as it has a low C:N ratio.  This is the reason why farmers seldom convert rice hay (or corn stover) into compost. They would rather use rice hay roughage, or kindling for fine.

      In terms of dry weight, rice hay contains very low nutrients - 0.86 percent Nitrogen, 45.91 total Carbon, 0.16 Phosphorus, 2.84 Potassium.  Compare this with the analysis of dry farm manure (carabao): 1.02 N, 10.66 C, 5.33 P and 1.92 K, whereas dried wild sunflower contains 5.53 N, 55.83 C, 0.36 P, and 2.78 K.  Soil on the other hand contains 0.13 N, 1.49 C, 28.36 P and 0,01 K.

      It is clear that the incorporation of topsoil, manure and wild sunflower in the compost pile will boost nitrogen (N), carbon (C), Phosphorous (P) and Potassium (K) elements therefore, increasing the nutrient value of the finished compost.

      This means that the C:N becomes closer to 30:40 the more valuable a compost it becomes, while the rate of decomposition is accelerated. By maintaining moisture content at 60 to 70 percent and temperature at 50 degrees centigrade in the initial two weeks, the pH level stabilizes at 6 to 8pH.  This is favorable to the development of biological and chemical reactions.  

      Composting then, basically, is following nature’s formula.  In nature, crop residues are left on the field after harvest and allowed to decompose or be eaten up by animals, was likewise leave their dropping on the ground. In both cases, the end products become part of soil together with weeds and other plants that are normally incorporated during plowing. This may be augmented by green manuring, the planting of leguminous plants like Indigo (Indigofera hirsuta L) which is purposely incorporated into the soil before the planting season.

      This system traditional practice, holds the key to sustainable productivityof centuries-old farmlands. It is also common in agricultural societies throughout the world, having evolved naturally. Traditional farming, after all, is a shared experience with man living in harmony with nature.  What type of judgment can man give to modern agriculture which uses synthetic inputs, offering high production outputs, but leaving the farms despoiled in the process?    

      Perhaps we should turn our attention to another example of natural composting.  The floor of a forest is continuously being built by composting.  It is a living carpet inhabited by a complex population of organisms responsible for converting organic materials into inorganic and elemental forms. These are then recycled, down to the succeeding generations of organisms.
 Closeup of the flowering plant  

      Natural composting is also observed in insect eating plants like the pitcher plantand the sundew.  It is demonstrated in the watery axils of bromeliads (tropical American herbaceous plants like pineapple or Spanish moss), which trap water and dirt. This mini pool is home to wrigglers, frogs, fish and reptiles. It is no wonder how bromeliads can live an epiphytic (living on the surface of plants) existence without reaching the soil for subsistence.

      The ant plant is another example.  Its bulbous rhizome (causing to take root) is filled with a colony of ants that “eat” through a complex tunnel network.  The inside is a laboratory which produces organic materials that the plant uses for its growth.  This is a classical example of symbiosis.
 
      Next time you find wild sunflowers growing where a lot of farm residues are available but wasted, think of the potential organic fertilizer that can be produced. It is the key to natural and environment friendly farming.  In nature, nothing is wasted. ~

Shot holes caused by bagworm (Cryotothelea heckmeyeri) besiege a talisay tree (Terminalia catappa), Cebu City 


                            Pagoda bagworm, Crypothelea hekmeyeri Heyl., in pseudo colony 
                            on duhat leaf; below, enlarged side view of the pagoda-shaped insect.


Sheepishly she peeps from under a pagoda she built;
Like the turtle she hides, creeps ‘til finally ceases to eat.
A Venus de Milo she emerges, sans wings she must wait,
Love scent in the air she urges a winged groom her mate.

She lays her eggs in the tent, broods them ‘til they hatch,
With heart’s content; leaves and dies after the dispatch.
To the Great Maker, life’s full of sacrifice and obligation;
Mother keeps young and home, the species’ bastion.

- AV Rotor, Bagworm
Light in the Woods, 1995

My pastime reading under a spreading duhat tree standing at the backyard of our old house was disturbed one summer. This favorite shady spot almost disappeared as the tree my father planted before I was born completely shed its leaves. Our yard turned into a litter of leaves. Our tree appeared lifeless.

Summer is when this tree is a deep green canopy, loaded with flowers and luscious, sweet fruits, and laughing children, their tongues and hands bearing the stain of its black berries.

The culprit cannot be the drought spurred by El Nino, I thought. Duhat is highly tolerant to prolonged dry spell, because its tap roots can reach deep seated ground water.

Even before I discovered the culprit - a shy insect protected by a pagoda-like bag - my children had already set up a field laboratory in their a tent, complete with basic research tools, and books of Karganilla, Doyle and Attenborough. For days our backyard became a workshop with the touch of Scotland Yard, Mt Makiling and Jules Verne.

My children called the insect living pagoda because of the semblance of its house with the Chinese temple, and because of its turtle-like habit of retreating into its bag. Leo, our youngest fondly called it Ipi, contracted from “insect na parang pagong at pagodang intsik”.

Ipi belongs to the least known family of insects, Psychidae, which in French means mysterious. Yet its relatives, the moth and the butterfly, are perhaps the most popular and expressive members of the insect world.

Curious about the unique bag and how it was built by such a lowly insect, Matt and Chris Ann worked as research partners. They entered their data in a field notebook as follows:

1. Base diameter - 2 cm
2. Height of bag - 2 cm
3. No. of shingles on the bag - 20
4. Size ratio of shingles from base to tip – 10:1
5. Basic design – Overlap-spiral

We examined the specimen in detail with a hand lens and found that the bag has several outstanding features. My children continued their data entry, as follows:

1. Water-resistant (shingle roof principle)
2. Stress-resistant (pyramid principle)
3. Good ventilation (radiator principle)
4. Light yet strong (fibrous structure)
5. Camouflage efficient (mimicry and color blending)
6. Structural foundation - None

The pagoda bag has no structural foundation, I explained. It is carried from place to place by a sturdy insect which is a caterpillar, larva of a moth. Beneath its pagoda tent, it gnaws the leaf on the fleshy portion, prying off the epidermal layer to become circular shingles. Using its saliva, it cements the new shingles to enlarge its bag, then moves to a fresh leaf and repeats the whole operation. As
the larva grows, the shingle it cuts gets bigger,

This is a very rare case where construction starts at the tip and culminates at the base, noted my wife. Remember that the structure is supposed to be upside down because Ipi feeds from the underside of the leaf, I said. “An upside pagoda,” our children chorused.

As Ipi grows, the shingles progressively increase in size and number, thus the bag assumes the shape of a storied pagoda. Thus there are small
Pagodas and larger ones, and varied intermediate sizes, depending on the age of the caterpillar which continuously feeds for almost the whole summer during which it molts five times.

If there are no longer new shingles added to the bag it is presumed that the insect had stopped growing. It then prepares to pupate and permanently attaches its bag on a branch or twig, and there inside it goes into slumber. The attached bag appears like thorn as if it were a part of the tree, and indeed a clever camouflage on the part of the insect. Here suddenly is a parasite becoming a symbiont, arming the host tree with false thorns!

My children's curiosity seemed endless. I explained that like all living things, bagworms have self-preserving mechanisms. They must move away from the food leaf before it falls off. They must secure themselves properly as they tide up with their pupal stage. After a week later they metamorphose into adults. Here on the twigs and branches they escape potential predators. Here too, the next generation of newly hatched larvae will wait for new shoots on which they feed.

Matt picked one bag after another to find out what stage the insect is undergoing. I recalled my research on Cryptothelea fuscescens Heyl, a relative of C. heckmeyeri, the pagoda species. Chris Ann took down notes

1. Specimen 1 - Bag is less than 1 cm in diameter, caterpillar in third instar (molting), voracious feeder.

2. Specimen 2 - Bag large, construction complete, insect in fifth or sixth instar, morphological parts highly distinct, head and thorax thick, three pairs of powerful legs.

3. Specimen 3 - Insect in pupal stage, expected to emerge in one week, chrysalis (skin) full, dark and shiny. Feeding had completely stopped.

4. Specimen 4 - flag empty, opening clear, chrysalis empty.

5. Specimen 5 - Bag contains eggs laid on cottony mass, chrysalis empty.

The last specimen is intriguing. Where is the insect? Why did it abandon its lifelong home? A puzzle was painted on the face of our young Leo. So I explained.

Let us trace the life history of Ipi and its kind. Both male and female bagworms mature into moths. The winged male upon emerging from his bag is soon attracted by love scent emitted by a waiting female moth still ensconced in her bag. The scent is an attractant scientists call pheromone. Then in the stillness of summer night, her Romeo comes knocking. Without leaving her bag she receives him at an opening at the tip of the pagoda bag. A long honeymoon follows, but signaling an ephemeral life of the couple.

The fertilized female lay her eggs inside the bag, seals it with her saliva, then wiggles out to the outside world but only to fall to the ground - and die, because Nature did not provide her wings!

“Poor little thing,” muttered Cecille apparently in defense of the female species. “Nature did it for a reason,” I countered, “otherwise we would not have bagworms today.” The wingless condition of the female bagworm is the key to the survival of the species.

The sun had set, the litter of leaves had been cleaned up. And the silhouette of our leafless duhat tree against the reddening sky painted gloom on our subject. As dusk set in, I noticed nocturnal insects circling the veranda lamp. A moth paused, then passed over our heads and disappeared into a tree. “Bye, bye,", cried Leo Carlo.

Summer was short, the rains came early and our duhat tree developed robust foliage. Cicadas chirped at the upper branches and an early May beetle hang peacefully gnawing on young a leaf. I was reading Rachel Carson’s Silent Spring when a gust of wind brought down a dozen tiny bagworms hanging on their own invisible spinnerets. My children were aroused from their reading of The Living Planet.

We had unveiled the mystery of the pagoda bagworm, but above anything else, we found love and appreciation on the wonders of Nature and the unity of life itself. ~~
Another species of bagworm (Crypthothela fuscescens Heylerts),  Family Psychidae. Photos taken at Angels' Hills, Tagaytay. The larva builds a bag of dried twig of the same diameter and length and attaches on the host plant until it reaches maturity.  The spent bag simply remains hanging. Lower photo shows an exposed larva purposely for study.

Photos taken at Angels' Hills, Tagaytay.

Bagworms make bags out of pieces of stems and leaves attached to the host plant. The male insect emerges leaving behind its molt at the opening of the bag. The female is wingless and does not leave the bag. When ready for mating she exude sex pheromone to attract a winged male through the posterior opening to fertilize. After laying her eggs inside the bag, she pushes her way out and drops to the ground and dies. In a week's time the hatchlings emerge from the nursery bag and soon find food and start building their own bags. Lowest photos: full size bagworms. The caterpillar molts five or six times before becoming into pupa, and consequently adult. Exposed caterpillars in their fifth and final instars.

1. Man has emboldened the causative agents of human diseases – both old and new - into epidemic and pandemic proportions, which include HIV-AIDS, SARS, Ebola, and today’s threats of pandemic diseases, the Avian flu (caused by a new virus H5N1, a hybrid of the human flu virus and the bird fly virus) and obesity (caused by Ad36 virus) - and the most recent MERS-CoV (Middle East Respiratory Syndrome Corona Virus).

2. Through biological specialization or mutation – natural and man-induced – causative agents have crossed natural barriers of transmission across species, such as bird to man (bird flu), civet cat to man (SARS), and primate to man (HIV-AIDS, and Ebola). Man has built bridges between the non-living to the living as well. We have paved the way for the Prion, an infectious protein, the causative agent of Mad Cow Disease or BSE (Bovine Spongiosform Encephalopathy) to cross from cattle to man and cause a similar disease affecting humans, the Creutzfeldt-Jakob Disease (CJD). Viruses have acquired new ability to infect and spread not only among humans but also in animals and plants. Viral diseases of plants have been responsible for the decrease in agricultural production in many parts of the world.

3. In the midst of enjoying the good life in a postmodern world more and more people are victims of accidents, heart attacks and strokes, anxiety and depression – and various forms of psychosomatic disorder - that often lead to ruined lives and suicides. Cancer, diabetes, and the deleterious consequences of vices (tobacco and alcohol), are on the rise among other modern diseases. Surprisingly, the number of years a person is healthy in proportion to his life span is not significantly longer than that of his predecessors, and that a person’s life span has not significantly increased at all. It is the average longevity of a population that has increased, not the individual’s. The fact is that modern medicine has increased survival of infants and young people, most of them are now in their past fifties, thus gross longevity appears to have increased, up to 78 years in some countries. On the contrary, more and more young people are getting sick and dying.

4. Modern society and science and technology no longer fit into the Darwinian theory of natural selection. There is a growing burden placed on the shoulders of the able and fit in our society who, without choice, is responsible in taking care of the growing number of dependents – many are the infirmed and the aged.

All these lead us to re-examine our values. It challenges us to look deeper into a paradigm of salvation through our concern for the environment. The prolificacy of the human species sans war and pestilence, plus growing affluence of our society has led to a population explosion which had doubled in less than fifty years. We are now 7.5 billion. Under this paradigm, there is no master and subject. All must join hands to prevent the exploitation of the earth’s finite resources. Today’s economists must also be good housekeepers of Nature, so with those in the other professions. While man’s aim is directed at the Good Life, he has unwittingly reduced the very foundation of that good life – the productivity and beauty of Mother Earth.
---------------------------------------------------------------------------------------------------
There are few frontiers of production left today. We have virtually pushed back the sea and leveled off the mountain. Prime lands have all been taken, swamps have been drained, and even deserts are being reclaimed. But as we continue to explore the marginal edges of these frontiers the more we are confronted with high cost of production that is levied on the consumer, and more importantly, the danger of destroying the fragile environment. AVR
---------------------------------------------------------------------------------------------------
Ecological paradigm endorses an ecocentric approach where all forms of life and non-life are important to human life. Spirituality points out to a unitive force: the sacredness of everything. God’s divinity flows in everything. There is integration in the universe. And we are part of that integration, exceedingly small as we are, notwithstanding. Under ecological paradigm of salvation, the one responsible in the destruction of the environment leading to loss of lives and properties should be held accountable for it to God, nature and fellowmen.

The environment and the economy need not be viewed as opposites. It is possible to have a healthy environment and a healthy economy at the same time. More and more businesses have begun adopting this concept as a business philosophy. People behind business organizations are becoming more aware of the ethical decisions they face, and their responsibility for their consequences.

Industrialization and urbanization are akin to each other. Industrial growth spurred the building of cities all over the world. Today there are as many people living in cities as those living the rural places. A mega-city like Tokyo has a population of 15 million people. We are 10 million in Metro Manila. Cities are fragile environments. Cities are more prone to epidemics such as the bubonic plague that killed one-third of the population of Europe in the 13th century. Now we are confronted with HIV-AID, SARs, Meningo cochcimia – and the dreaded Avian flu which hovers as the next human pandemic disease. AVR

There are organizations that have set some rules of governance of the environment, among them, GRI (Global Reporting Initiative), CERES (Coalition of Environmental Responsible Economies), and UNEP (United Nations Environmental Program). In line with these a multi- national corporation came up with the following thrusts:

• Restore and preserve the environment
• Reduce waste and pollution
• Education of the public on environmental conservation
• Work with government for sound and responsible environmental program
• Assess impact of business on the environment and communities.

This approach is gaining respect and more and more businesses are looking at this model with great interest and favor.

The Question of Governance

Dr. Tai cited three themes in order that man can live in harmony with nature. Man is part of the ecosystem, Man is steward of the earth, and Man is finite. Dr. Tai cited models with which man can change his views about the environment and change his style of living. We have also models in the business world, in the church, and in the government, in fact all sectors of society. There are models everywhere in this or that part of the world, whether developed or underdeveloped. There are as many models in less developed countries as in highly industrialized countries. It could be that the less developed are closer to tradition, and still have strong ethnic roots, like the old civilizations mentioned in the paper – the native cultures of America and Africa.

But the world has never been one. It has become more diverse in views and interests though in many respects share the same aspirations towards progress and development. And this is the problem. Man is always in a race. In that race awaits at the end not a prize mankind is proud of and honorable. It is tragedy, which Garett Hardin calls, the tragedy of the commons. It is a greedy competition for a finite resource, each his own, until it is gone. The forests are disappearing today, the lake are dying, the fields are getting marginal, the pastures are overgrazed, the air is loaded with destructive gases, the sea  is over fished. All these point out to the syndrome - tragedy of the commons. And because time is of the essence, many believe that the world needs a new revolution now? Is revolution the only way to solve global problems of the environment today?

Definitely, while we need to reform to save our environment, any means that is contrary to peace and unity, is definitely unacceptable. And we would not adhere to the rule of force or violence just to be able to succeed. It is said, that revolution starts in a small corner. It starts in this congress.

Ethics is the foundation of aesthetics; it is something very difficult to explain that makes beautiful more beautiful, rising to the highest level of philosophy where man find hope, inspiration, and peace. It is a beacon. While ethics sets the direction, aesthetics is its beautiful goal.

In closing I would like to thank Dr. Tai, for his scholarly and incisive paper from which I was not only able to prepare myself as a member of the panel of reactors, but found an opportunity to review and expand my current research works in ecology as well. Lastly, I would like to recite this short prayer I made for this International Congress on Bioethics, and dedicate it through the little child who visited the two workshops in the village and exclaimed. “But there are no neighbors! But there are no trees, birds, fields and mountains!”

Ecology Prayer

When my days are over,
Let me lie down to sleep
on sweet breeze and earth,
in the shade of trees
I planted in my youth;
since I had not done enough,
make, make my kind live
to carry on the torch,
while my dusts fall
to where new life begins –
even only an atom I shall be,
let me be with you,
dear Mother Earth.

There was once a town in the heart of America where all life seemed to live in harmony with its surroundings…Then a strange blight crept over the area and everything began to change …Mysterious maladies swept the flocks of chickens, the cattle and chicken sickened and died …There was a strange stillness… The Few birds seen anywhere were moribund, they trembled violently and could not fly. It is a spring without voices.

Happy faces. Participants in an ecology seminar, Faculty of
Pharmacy, University of Santo Tomas 
with author, 2010.


----------------------------------------------------------------------------------------
Author’s Note: In a forum at UST, I described our society in the like of a global village where cultures, races, creeds, and the like, are converging, the East and West in a continuing interaction since Columbus time. Then I raised some scientific findings that are revolutionizing man’s thinking today. Lastly I asked, “Can man lead a life in which he can see and realize the true beauty of life?

In this particular series, Halls are seldom made into war rooms. It is important I believe, to raise warning so that we may not fall victims to the syndrome of The Fiddler on the Roof. In the novel of the same title, a Jewish community which was finely built by tradition, and perished holding onto it in the face of a fast changing world, and cruel one at that.
-----------------------------------------------------------------------------------------

As I listened to a lecture Science as Critique of Society, these scenarios, which are happening outside of the hall, came rushing into my mind. I am sure the audience invariably shared with me in the imagery of these current events.

o The whole world holds its breath at the current crisis in Syria, and recently in Ukraine.   North Africa and the Middle East have yet to face the consequences of Arab Spring. North Korea and Iran are still stubborn on nuclear disarmament, and the US is extending is presence in Iraq and Afghanistan.  

o Terrorism is today's enemy of the world, its tentacles have already grown widespread even before the 9-11 attacks on the World Trade Center, NY. As a boundless, invisible organization founded on hate and destruction, it undermines the present world order, particularly capitalism. We have our own share of terrorism in the Philippines and it is a serious one.

o More than conventional weapons, terrorism is employing biological and chemical warfare – and not remote, nuclear weapons - the very tools used by the superpowers themselves against “enemies.” These weapons are around us and may be right in our backyard. It is not remote that the Philippines is in the target list. With the state-of-the-art of weaponology war is going to be fought by remote control using sophisticated drones both in air and sea.  Drones. 

o Polarization is not limited to politics; it extends as well to religion, reminiscent of the Dark Ages, when people were pitted against each other by their faiths. Egypt today is facing religious conflict as an aftermath of the Arab Spring people's revolution (Time, April 13, 2014). 

The hall was attentively silent. I did not quite understand why these issues were generally left out. The lecture nonetheless provided the ambiance of these scenarios.

o Oil prices continue to spiral with four increases in price in a row, triggering increase in prime communities and basic services, exacerbating our already weak economy. Global energy crisis looms in the current conflict in the Middle East and North Africa, the world's main suppliers of oil.

o Mass evacuation of Overseas Workers who are in the war zone has nightmare stories to tell. Two things our country loses everyday: tremendous cost of evacuation and slowdown of dollar flow from the remittances of the OFWs.

o To worsen our fear the world has plunged into another climatic episode, this time El Niño, a climatic phenomenon characterized by extreme drought. Spontaneous forest and brush fires are occurring in Australia, US and Indonesia. The Philippines is projected to have poor harvest in rice and corn and this is expected to continue until next year.

o Food security as key to maintain our economy is difficult to attain, what with 10 percent production shortfall in rice, 30 to 40 percent in corn? We also fall short in the production of meat, poultry, fruits and vegetables. Yet we have IRRI and UPLB, the alma mater of scientists of foreign countries that now export agricultural products to us in exchange for the knowledge they earned.

o For a rich agricultural country such as ours, the need for a huge buffer stock is ultimate recourse since it is feasible to build one from local harvest. But this is not the case. For this year, we are going to import rice in the tune of 1.5 million MT to maintain supply-demand balance and to provide buffer stock, from Thailand and Vietnam, and a part from China, Pakistan and India.

o On the side of space science and technology, the bold plan of the US to send man into space has been held off since NASA’s space shuttle Columbia exploded on impact with the earth’s atmosphere as it was returning from a successful mission. All 7 astronauts were killed. Definitely this accident has set back man’s conquest in space. It is a requiem for mankind, following John Donne’s “A little bit of each of us dies.” (On the Death of Strangers)

o It is a paradox that in this modern age of medicine, one of the leading causes of death in US hospitals is doctor’s error, chiefly wrong diagnosis and over treatment. Yet we are going to embark into a new field of medicine, gene therapy. Are doctors really prepared for it?

o Now this is interesting. Among the ten major causes of death in industrialized countries are those associated with the good life such as heart attack, severe depression, accidents, diabetes, and the like. What is good life then?

o On the other hand millions of people die every year from the ancient scourge of mankind – tuberculosis, respiratory diseases, infections, childbirth, and many other diseases associated with poverty and malnutrition.

o The lack of doctors and healthcare exacerbates the suffering of millions more, especially the children, who are victims of malnutrition and poverty. We witness the growth of slums, and a runaway population, and we stand there unable to alleviate their plight.

According to Susan George in her book, How the Other Half Dies, people either have too much or too little. As this is traced to his nature and the institutions he made. Because it is a question of governance, man holds much faith in his ability to solve the problems of his society. But the UN has not lived up to the expectations of the world. The EC is too regionalistic, so with ASEAN. But the holding of summits and conferences attests to man’s immanent goodness, and in spite of our limitations we have gone a long way towards progress.

Indeed science has definitely contributed to man’s success to this point. But to where does science ultimately lead us?

Science should challenge the intellect, touch the heart, show the path the citizen should take, and enlighten the man on the street.
----------------------------------------------------------------------------------------

Let us consider these issues.

o Sixty percent of us Filipinos live below the poverty line.
o Exodus to cities and abroad seems unstoppable.
o There is breakdown in peace and order.
o Loss of species is rampant, but loss of entire ecosystems is more damaging.
o Liberalization is trade and commerce exacerbates the gaps between rich and poor nations.
o Values seem to be taken for granted.
o Conditions in the slums are virtually sub-human.
o Forty percent of our youth do not practice their religion.
o Ignorance and illiteracy is prevalent – and increasing.
o Government service is generally poor and riddled with graft and corruption.
o Diseases can develop into epidemic proportion as in the case of bird flu and SARS.

It is an open-ended list of issues science should address itself. But we can not wait too long.

While the conflict in North Africa and the Middle East rages, global warming is stirring the cauldron of global climate and local weather, more and more natural and man-induced calamities at increasing intensity such as the earthquakes in Haiti, Peru, and Japan with a new record of 8.8 on the Reicher Scale. Hope dims and faith may not hold on for long. As the world prays, the hall is silent.

Meantime North Korea’s nuclear program has emerged as a new threat to the region and to the world. But South Korea, which is expected to reunify with the North soon, is apparently undisturbed - seemingly so with certain countries. Will US apply stricter sanctions on North Korea? Will Japan now consider re-armament? What is our stand with these developments? Is this the beginning of a third force? As the world waits, the hall is silent.

Where is peace and quiet for man and his society?

Part 3 - Bioethics: The Ultimate Expression of Values

Dr Abe V Rotor

Paolo drew one, last deep breath and held it there as if forever. His eyes were
wide open, glassy and welled with tears. His pale lips went agape as his whole body tensed. That was the arrival of the inevitable moment when he gave up fighting for life.

  Paolo  

Immediately, doctors, working with quick hands put the boy’s body under the command of modern machines like: a high voltage cardiac resuscitator; a lung machine that works on the principle of our diaphragm; and electronic gadgets to monitor pulse rate, body temperature and blood pressure. The sight of wires and tubes all over the young patient, with doctors working double time, reminds one of the desperate, but futile, effort to save the mortally wounded President of the United States, John F. Kennedy, in a Dallas hospital on November 22, 1963.

      This situation also reminds one of the celebrated Karen Quinlan case. This is about a young woman, who remained in a state of coma at a US hospital for more than a year.  Since her condition was not improving, she was unplugged from her life-sustaining machines. The case became an issue of a long court battle.  In the end, the patient was allowed to die, unplugged from her machines. 

      The court’s decision leaned heavily on the principles of bioethics. These principles continue to influence similar cases today, some 30 years later. Bioethics, the ethics of the life sciences, offers guidelines for dealing with life-and-death decisions. The ethical principles involved are expressions of values, and the humane foundations of moral values.

      In both the cases of Paolo and Karen, we ask? What is clinical death? Is the prolongation of life with machines (despite certification of a hopeless condition), justifiable?  In short, is keeping people alive through artificial means ethical? 

      By analyzing the interrelationships of ethical principles, we conclude that the human being must be respected. Allow him to die peacefully and let the bereaved family realize God’s sovereignty over life and all creation.

Bioethics and Social Justice

      Outside the hospital, people needing immediate treatment, are waiting for their turn.  There are those, mostly poor, who have been waiting silently in prolonged agony. In remote towns and villages, it is considered a luxury to have a doctor around. The medical care most poor people know are unreliable, often associated with superstitious beliefs. What an extreme scenario from that of Paolo and Karen!

      Thus bioethics and social justice must go hand in hand as we view its application upon the millions of poor people who are dying without benefit of good medicine. Like in war, precious medicine is applied on the potentially salvageable, and denied for those who are dead or beyond help.

      Yet there are those who feel privileged with “over treatment”. This is why we question the morality of cryogenics (dealing with the effects of very low temperatures), its lavishness and futuristic goals.  There are over a hundred rich people in America today whose bodies lie in cryogenic tanks, awaiting the day when medicine shall have found a way to revive them.

 ------------------------------------------------------
      “In the real sense, the practice of virtue is what morality is all about, meaning lived morality, the morality that leads to self-realization and ultimately, happiness.  After all, virtue is the road to happiness.”
                            
   Fr. Fausto Gomez, OP, STD, Relevant Principles in Bioethics
-------------------------------------------------------

      Here is another example of social injustice. The US spends US$1.5 billion daily on healthcare, even as more than a quarter of its population are deprived of medical benefit. One can imagine the tremendous contribution to world peace and improvement in the quality of human life, if only a portion of this wealth and that used for resurrecting life is diverted to the plight of the world’s poor.

Bioethics and Disease Prevention

      Dr. Mita Pardo de Tavera is a doctor who believes in the primary health care approach of involving people’s full participation. She raised ethics of  appropriability disease prevention as superior to its cure. This approach should be part of a program to eradicate diseases such as tuberculosis. The solution is not to be dependent merely on medical approaches, but on sound socio-economic programs as well that deal with illiteracy and unemployment. 
Pillars of Bioethics

      The broad domain of bioethics rests on four pillars, as follows:
§  Truth
§  Compassion
§  Beneficence
§  Justice

      Goodness springs from every righteous person when dealing with questions on bioethics.  It is conscience, that inner voice which makes us conscious of guilt.

      But how good is good enough?  To answer this question, we have to qualify conscience as formative conscience.  Fr. Tamerlane Lana OP STD, rector of the University of Santo Tomas, emphasizes that the formation of conscience is a life-long task, especially for professionals whose decisions directly affect the lives of people. The goal is for them to attain a well-informed conscience, which is upright and truthful, and that does not rely merely on acquired knowledge. It has to be a conscience guided by the spiritual nature of man.

Growing Application of Bioethics

      Today, with man’s growing affluence we find bioethics as part of the expanding fields of science and technology, areas that have direct consequences affecting human life.  Thus, we hear people raising questions of morality and ethics in various areas such as:

§  Euthanasia.
§  Hospice management.
§  Organ transplantation and rehabilitation.
§  Contraception, abortion and sterilization.
§  Social justice in the allocation of healthcare resources.
§  The Human Genome Project (HGP), and genome mapping.
§  Genetic engineering and human cloning.
§  In vitro fertilization (test tube babies).
§  Surrogate motherhood.
§  Menopausal childbirth technology.
§  Induced multiple births.
§  Aging and extension of longevity.
§  Pollution and global warming.
§  Ecosystems destruction.
§  Thermonuclear, biological and chemical warfare.

      These areas of concern in bioethics are expanded into medical ethics for doctors, lawyers and scientists to know. These include the following cases: 

1.     Food Additives and Contamination.

      Vital issues of discussion are the manufacture and distribution of food laced with harmful substances like potassium bromide in bread, sulfite in white sugar, nitrate in meat, glacial acetic acid in vinegar, monosodium glutamate (MSG) in cooked food, and aspartame in softdrinks.  Many of these substances are linked to cancer, diabetes and loss of memory.

2.     Ecological Bioethics.

      “Is it a sin to cut a tree?” a student asked this author.

      This is a bioethical question. It is not the cutting of the tree, per se, that causes the “sin”. Rather, it is the destruction of the ecosystem, the disruption of the functioning of natural laws resulting from the tree cutting, that is considered unethical.  

      The unabated logging of the watersheds of the once beautiful city by the sea – Ormoc City in Southern Leyte -  caused massive mudflows sweeping the central part of the community and killing hundreds of residents. Yet the ethics and morality of the actions of the loggers were never questioned.

       In the realm of theological sciences, this tragedy is akin to the paradigm of salvation.  According of Fr. Percy Bacani CICM, it is a sin to harm the environment, because it causes people to suffer. To find salvation, the culprits of the Ormoc tragedy should plow back their ill-gotten wealth for rebuilding the community they destroyed. The morality of this paradigm touches deep down at the roots of moral philosophy.

Five Principle in Bioethics

      Basic questions are raised where bioethics and moral philosophy are involved. These questions may be categorized under five general types.

§  When are we responsible for the consequences of our actions? (Principle of indirect voluntary).
§  How far may we participate in the performance of evil actions done by others? (Principle of cooperation).
§  When may we ethically perform an action from which results in two effects, good and evil? (Principle of double effect).
§  Are we the lords of our lives and all creation, or only custodians thereof? (Principle of stewardship).
§  Is the good of a part subordinated to the good of the whole? (Principle of totality).

      These general ethical principles serve as guides in analyzing situations, making decisions, or forecasting the consequences of one’s actions. These principles are used in law, philosophy, theology, management and other disciplines. The values on which they are founded which, in turn, provide the virtues that guide our actions, remain unchanged.

      Why do we not always follow the dictates of our conscience? “It is because we are weak, or blinded by sin or vice. Or because we lack virtue and fortitude,” says Fr. Fausto Gomez OP, regent and professor of bioethics at the UST College of Medicine.

      Man has yet to learn to avoid evil, and to do good.  Temptation leads one to sin, but so does complacency and inaction.

      On that fateful day, Paolo my hero, was the focus of a most crucial decision the doctors, my family and I had to make. When we made it, the life-sustaining machines were finally removed that day in 1983. Paolo died in my arms. He was my son. ~

Young fronds of coconut are offered on Palm Sunday. Thousands of coconut seedlings and trees are sacrificed, leading to the death of thousands of trees on a single occasion every year. Estimated loss runs to millions of pesos. The productive life of a coconut may extend to fifty years.  

The value of nuts and other products (tuba, midrib, husk, leaves, firewood, charcoal) produced by a single tree in a year is between P1000 to P5000. The same occasion endangers other species such as buri, anahaw, and oliva or cycad which are living fossils, and are now endangered species.  


Food additives like MSG (monosodium glutamate), artificial sugars (aspartame, nutrasweet, saccharin and other brands) destroy human health, in fact cause premature aging and early death.  

Intensive monocropping depletes soil fertility, and destroys physical properties, such as tilth, water retention, organic matter content, which are necessary to good production and sustainable productivity.~

Typical pineapple farm 


“It is harder to understand the behavior of human beings than to understand that of atom.”                   - Albert Einstein 
1. After applying insecticide against leafhoppers of mango, an orchard grower in Zambales indiscriminately threw into a nearby stream the sediments that settled at the bottom of the sprayer tank. Three days after, scores of fishes floated downstream. A carabao was also reported to have been affected, prompting the owner to slaughter it before its possible death. The poison: a phosphate compound several times more potent than the dreaded DDT. 

2. Mang Juan’s farm, located in Gapan (Nueva Ecija), is typically like those of his neighbors. It is planted to rice twice a year with the aid of irrigation. When this farmer decided to plant a variety of rice that matures in 90 days instead of the usual 120-day variety which his neighbors plant, he deprived a number of fields of the vital water. The situation was worsened when he decided to plant three crops of rice in a year.

3. Cabbage is grown extensively on terraces in Atok, Benguet. Farmers must cooperate in many aspects of production and marketing. For example, planting time is towards the end of the year. Pest and disease control must be synchronized, so with the time of harvesting in order to adopt a standard price policy. For one reason or another, a farmer abandoned his cabbage farm it to pests and diseases. Unsuspectingly diamond-back moth, a major cabbage pest bred on his farm, and in three quick generations, pest population spread throughout the valley resulting in crop failure in many farms.

4. With modern techniques, sloping land can be made productive and its productivity can be sustained. Among the cardinal rules of hillside farming is the planting of permanent crops such as orchard trees. Contour plowing and strip cropping are also advisable to prevent rapid runoff during rainy season. Mang Isidro, a settler occupying a 20-degree sloping farm, failed to adopt these practices. In after three croppings, he abandoned the farm. Erosion depleted the thin soil cover and destroyed the farms below his farm.

5. One of the major coconut oil companies in Manila contracted farmers in Samar who produce copra. Coconut oil is a main ingredient in soap manufacturing, and it is still the main vegetable oil used domestically and for export. The contract did well at first, until the farmers started to deliver inferior grades. Worse thing that happened was when rock and sand were concealed in the sacks of copra to increase weight. The company immediately terminated the marketing agreement.

6. Large mines in Benguet and Mountain Province dispose off their waste called tailings into natural waterways. Mine tailings reach as far as Tagudin, Ilocos Sur and cover vast ricelands in La Union, before flowing into the sea through the Agno and Amborayan rivers. Direct damage to crops is heavy. So with river and marine life, depriving fisherfolk of their livelihood. Mine tailings have irreversible ecological effects because of their toxic chemical content, among them cyanide and mercury.

7. Tobacco farmers are uncertain of the price of their crop this season. Like in the past many years, they are allegedly at the mercy of a powerful group that virtually controls the industry through cartel. In Ilocos Norte, tomatoes by the truckloads were dumped on the highway to dramatize their plight of farmers. The processing plant was not buying their crop at the agreed price and volume. Vegetable growers in Boguias, Benguet get advance cash from Divisoria traders payable in kind at harvest. These traders manipulate the prices for their crops. Farm price of cabbage alone may plunge to P0.50 per kilo at peak harvest.

8. Government importation policy under the “principles of deregulation, privatization and free enterprise” did not provide adequate protection to local corn growers, specifically in Mindanao, when private companies brought into the country volumes of cheap corn from the US and Thailand. It was reported that imported corn is cheaper than locally grown corn, which is of course an advantage to big poultry and hog raisers so that they would rather import corn, to the detriment of the local corn industry. Farmers question the rationale of annual importation of rice when the country has the potential capability to produce enough rice. (The Philippines imports 10 percent of its annual rice requirement, equivalent to one million metric tons.) Likewise, the import liberalization program is a disincentive to production, not only in agriculture but in industry as well.

9. From these examples the subject of this article is about values. These cases, and many more, can be observed in many places. By analyzing them we may offer solutions, or if there is none for the moment, provide certain insights that might help us in finding alternatives.

“The genuine meeting of minds may result if both parties in interest will concede to the other side the honor of believing, at least as an initial assumption, that its point of view is not merely vicious or silly”.  - George H. Sabine

Misuse and abuse of agricultural chemicals 

The Zambales incident is not an isolated one. The moral issue lies not only in the farmer but also other sectors involved the manufacture, distribution and use of not only insecticides, but the many farm chemicals used on the farm today. The unscrupulously use of farm chemicals has these deleterious consequences.

Edible frogs, fishes and snails have disappeared in many ricefields. Many birds and lizards have similarly disappeared due to cumulative toxicity from these chemicals. Soils repeatedly applied with commercial nitrogen fertilizers have become exceedingly acidic. Zinc deficiency is another consequence.


By substituting organic fertilizers with commercial ones soils tend to cake and crack easily. Organic fertilizer which serves as soil binder.
Lakes and ponds that continuously received runoff water from fertilized and sprayed farms have lose much of their productivity. Pollution reduces oxygen in water and favors algae bloom that ultimately results to “fish kill”. 

Excessive use of pesticides favors mutation. Resistance is built among the surviving pest and disease organisms so that there is need to increase dosage and rate of application. 

The lack of protection policy for local products is exacerbated by preference to cheap imported materials, resulting to dollar drain and indirect subsidy to foreign manufacturers. 

There is an increasing incidence of chemical-associated deaths from cancer, respiratory diseases, and other ailments. Residual toxicity is also believed to reduce life span. It predisposes people to secondary causes of death.

“Decay starts from somewhere, often indiscernible, or deeply shaded by the sophistication of the system.” - AVR 
----------------------------------------------------------------------------------------------------
Uncoordinated Farming 

This case illustrates conflict of interests among farmers. Uncoordinated farming is a situation where there is poor, if not lack of planning. It also shows highly individual attitudes. How do we visualize the setup as described in the case? Let us visualize the irrigation system emanating from a watershed and ramifying over the service area by a canal network.

In an irrigation cooperative, all farmer members must follow a unified planting schedule. For rice there are two main planting seasons, thus, there are two sets of water releases: June to October and December to March to coincide with the regular and dry season, respectively.

Why did the Gapan farmer deviate from the plan and dissociate from that of the association? Let us consider the following:

1. Palagad or summer rice crop requires a lot of water. Inefficient irrigation system can not guarantee enough water for the farms located downstream during summer, whereas they are prone to flooding during the monsoon months since they are situated at the lowest part of the field.

2. Vegetable growing is profitable, especially in Metro Manila. To get the most, vegetables growing must be “off-season.” By planting earlier and by using short maturing rice varieties, the farmer can plant vegetables soon after the rice harvest.

Deviation from the master plan is inimical to the attainment of objectives of an association. Individual resourcefulness by all means should not result in any detrimental effect to other members. On the contrary, it could be an important initiative to improve the current system. The advantages the farmer realized from his innovation may be common to many. A sectional area having the same prevailing conditions may develop a revised program, a specific cropping system that gives maximum returns on investment to all farmers within that given area. Thus, we see that an association should have the capacity to:

Adjust unanimously original plan to tap potential opportunities of production. Distinguish peculiarities that lead to the development of a sub-area that may have its own program and set of regulations. 

Adopt indigenous practices developed from prevailing local conditions in relation to agronomic, social and market factors.
Pursue strong leadership to transform a useful innovation for general good, instead of creating dissension and alienation among members.

We realize that there are farmers’ associations sharing irrigation facilities that have failed for a number of reasons and it would be a good lesson to enumerate those which are common.
  • Wasteful use of irrigation water. 
  • Stealing water from irrigation canals. 
  • Unscheduled releasing of water, thus adversely affecting nearby farms that do not need the water at the moment. 
  • Deliberate tapping of water from the newly fertilized adjacent field, in effect, “stealing” the dissolved fertilizer. 
  • Deliberate prevention of water flow, thus depriving others of the vital water supply. 
  • Throwing toxic chemicals, especially pesticides into the irrigation canal. 
  • Using irrigation canals for carabao wallows, in effect destroying their structure. 
  • Putting up fish pens and cages on the waterway, which does not only impede normal flow, and deprive others of the fish. 
  • Cutting of trees on the watershed and illegal pasture and kaingin farming on the watershed. 
  • Refusal or neglect to pay irrigation and association fees and obligations. 
  • Abandonment of farm leads to pest buildup 
When a farmer neglects his farm and gets little from his efforts, it may be casually dismissed as “Well, that is his choice. Who suffers anyway?” But if negligence leads to loss in others’ crop, as it is the case of the Atok farmer, it is another story. There ought to be a law to protect those who are victims of such negligence (or irresponsibility).
--------------------------------------------------------------------------------------------------------
The ethics of land use binds man to his obligation to nature.” - Aldo Leopold
--------------------------------------------------------------------------------------------------------
Let us enumerate the premise of the case of the farmer who abandoned his cabbage farm in Atok, a fertile pocket valley in Mt. Province. The semi-temperate climate is ideal to commercial gardening of temperate crops, chiefly crucifers that include cabbage, cauliflower, and lettuce.

The terraced farms are tilled by small farmers with the help of their respective households. The farmers are unorganized, except for selected groups and members of a marketing association.
Prices of vegetables vary and fluctuate greatly so that farmers respond to good price without warning, even if their crops are newly sprayed, or have not reached full maturity.

The cited case helps us visualize a situation where a neglected farm becomes the breeding ground of the diamond- back moth and the leaf miner, which are major pests of cabbage and other crucifers.

While this case may not merit a court case, its ethical repercussion cannot be easily dismissed in a closely-knit tribal community. But times have changed. Now “invaded” by outsiders who invest in farming in the area, many customs and traditions have been lost.

Other consequences in the neglect of duties and responsibilities of farming may be glimpsed from the following observations:
  • Delayed harvesting results in shattering of grains which means less yield and germination of volunteer rice making weeding complicated. 
  • Delay in processing such as drying of palay, causes considerable reduction of crop value. Postharvest loss could be as heavy as actual crop loss on the farm. 
  • Total abandonment of a farm has the worst effect because it develops into a place that harbors weeds, unwanted seeds, pathogens, insects, and other pest like rodents. 
We can add to the list virtually without end. We conclude that many of the so-called mistakes are, in one way or the other, negligence in disguise.

Let us look into this seemingly harmless farming system in its three stages.

Land clearing 
– “Slash and burn” follows cutting down of trees. Thus, the kaingero succeeds the logger and completes the destruction of the forest cover.

Cash cropping – Upland culture of seasonal crops like rice, corn, some legumes and vegetables intended for family consumption. This is kaingin or swidden farming, a kind of subsistence farming.
Spent kaingin areas are abandoned after losing soil fertility, in favor of newly opened ones.

The End of Agricultural Frontiers

With increasing pressure of population, new lands are placed under cultivation. But the frontiers are limited and are often too expensive to convert them into agriculture. Today’s technology offers opportunities to tap uplands and even hillsides. Farming these unstable areas requires greater skill than in lowland farms as far as ecological considerations are concerned. The pre-qualification of an upland or hillside farmer must therefore, be stricter.

First, higher capitalization requirement is needed for land development.

Second, a farming system involves proper combination of permanent, perennial and short- growing crops.

Third, crop diversity means integrated processing and marketing.

Fourth, there is a need for infrastructure development (e.g. farm-to-market roads, water impounding, terracing, etc.). This requires government support and operating capital.

 Capitalist farmers on the other hand may consider high and quick return on investment (ROI) more than enhancing sustainable productivity. As an alternative, farmers may be organized into a cooperative, and the sooner this is implemented the better are the chances of having productive results. Any further delay in the development of logged over areas, slope pastures and abandoned hillsides may eventually deteriorate to irreversible wastelands.

The fourth model is ideal. It can be packaged into an integrated development project. The holistic approach base on geographic profile has the following features: 


  • Maintenance/improvement of ecological balance. 
  • Equitable development to all sectors. 
  • Maximized resources utilization. 
  • Integrated of programs/project, including waste utilization and resources recycling. 
  • Setting of short, medium and long term objectives. 
The small farmer becomes a contributing unit to the whole system – not an individual producer who looks only for his own good and need. The capitalist will have to play an important role that is not only measured by economic parameters. Government, in cooperation with non-government organizations and the private sector will provide the overall umbrella that facilitates growth and development.

Production-Marketing Contracts

The essence of a contract is mutual trust. The paper merely formalizes this value. What happened to the Samar copra producers, as earlier mentioned, is a violation of that trust. So with the following cases: 

  • Mango growers/traders arrange the bigger pieces on top and the smell ones at the center or bottom. This is true with potatoes, onion, eggplant, cabbage, tomato and many others farm products. 
  • Short weighing is rampant. Lanzones sold in retail in short by as much as 25 percent. So with rice. It is not 50 kilos per bag but only 49 or even 47 kilos. Meat, fish and many market items are sold below weight. We imagine short selling of gasoline, which is supposed to be controlled by precise measurement and strict supervision. 
  • Inferior quality. Most commercially sold vinegar is diluted glacial acetic acid, an industrial chemical that is not intended for food. Patis (fish sauce), coffee, cocoa, flour, etc. are often adulterated. 
  • False labels and advertisement. We are sometimes deceived by aesthetic presentation of product on the label and on TV. Only half of the truth is said, if at all. 
Why do farmers cheat? So with big manufacturers? Again, we speak of values. The system allows cheating - or it provides a wide range of flexibility or opportunities that leads to cheating.

Marketing contracts should bind buyers in giving incentives to producers. Aside from this, central processing plants, assembly points, transport facilities, on-farm supervision and instructions, should be provided by buyers under certain mutual agreements. Risks should be considered a normal part of the contract, but previsions to safeguard both parties should be discussed and agreed upo

Tragedy of the Commons
We use this term coined by Garrett Hardin. Free-for-all leads to tragedy. These are examples that illustrate Hardin’s theory.

1. Overfishing of Laguna Lake

2. Logging concessions that led to deforestation

3. Pollution of the Pasig river

4. Mine tailing disposed into the river down to the sea

5. Unabated gathering of firewood in a public woodland

6. Trawl fishing in Manila Bay displacing the small fisherfolks
Commercial farms

“Free” use of common resources, Garrett Hardin explained, leads to mass poverty. To wit:

“The logical outcome of each atomistic user maximizing only his own private benefit from a free common, under conditions of population exceeding its carrying capacity, is the inevitable reduction of each and everybody’s benefit.” ·

It’s like an Edgar Allan Poe’s story of death tapping on “a night dark and dreary”, but in this case it is not a raven. It is the Death-watch Beetle (Xestobium rufovillosum) that is alluded to death. It is an insect with a scary habit all right. The name was derived from the tapping sound it produces, which is frequently heard during mating period, usually in April or May.
Death-watch Beetle - the harbinger of death 
Photo acknowledgement: Wikimedia Commons.

The beetle simply jerks its body forward in rapid succession, and strikes each time with the lower front part of its head against the surface on which it happens to be standing. It gives eight taps in slightly less than a second; and almost before it stops another beetle of its kind that is within hearing distance will respond by tapping back in the same quick manner. In woodworks and furniture that have been attacked by the Death-watch Beetle, the worm holes are large and distinguished by the presence of frass and powder around the openings.


Powder post beetle or furniture beetle

The beetles are from one-fourth to one-third of an inch in length, dark brown in color, spotted and banded irregularly with thick patches of short yellow gray hairs. Pairing takes place after the beetles have made their exit from the wood, and they die a few weeks later, the female in the meantime having laid some 70 eggs. The tapping is of the nature a sexual call, and may be repeated over and over for quite a long time. Grating sound may also be heard as the larvae gnaw on wood inside its tunnel. It takes three years to complete the insect’s life cycle. A more familiar beetle, Anobium punctatum, is called powder post or furniture beetle, named after the dust it scatters at the mouth of its tunnel on furniture.


Next time you hear death knocking in the night, think of it, it is just coded expressions of insects in love. ~

Preserving the Quaintness of a Town Fiesta 
Dr Abe V Rotor
Quail raising for meat and eggs has become popular locally. 
It requires little space compared to raising chicken and other fouls. 
  
Quail eggs, you can hear by her lips' language;
each bearing markings like Nature's map;
I wonder if it leads to a treasure somewhere -  
Yes, to the nest of the pugo once wild.     

Fans made from leaves of the buri palm (oval); folding fans (right) 
made of bamboo and fabric, and hand painted with many designs.
 Philippine landscape is among the favorite choices. 

Fans, fans, everywhere - who needs an air conditioner?
they turn the air into gentle breeze, 
deliver it fresh with scent of perfume in some corner;
it's an art of friendship, love and peace.  

Boiled corn cum cob and husk is either for a meal or a snack.  Corn is the second staple food of the Filipinos after rice, the main staple in Mexico, and many countries in South America, the Pacific, and other parts of the world. 

Corn-on-the cob in floral design 
for the hungry or just passerby,
steaming and hot to the touch, 
which makes eating a pure delight.

Religious items from candles to figurines, prayer book to mass cards are sold within the premises of the church even without any special occasion.  It shows the deep religiosity of Filipinos, and their belief in miracles.   


Deep is your faith indeed if you have a collection 
of religious icons, artifacts and memorabilia;
an altar they make in your home next to the church, 
a bridge to God - and to the great mystery.   


Name it, and the vendors have it. What the malls and supermarkets 
can't provide, they do - at friendly suki terms, including four gives, 
five-six. No exchange, no return is not in their rules. 

Vendors, vendors, everywhere there is no escape,
anytime on the sidewalk or road, at your gate;
really, who says there's problem of employment?
self-made, self-reliant, a brave breed they make.

Bargain, Sale. It's a selling strategy.  It means selling at a 
special price. It may be buena mano, to start the day lucky.   


There's nothing so small to be insignificant in business,
for every cent growas bigger and farther;
patience, tiyaga at sigpag, leave to tadhana the rest;
what matters most, you're your master. 

A diversity of items on display.  You really can't pass by empty handed. 
  
Diversity the key to a  country fair;
all things big and small;
A wide range to browse and to scan
even only to pick just one.

Native grapes, green but sweet and seedless. Why import?  

More fancy than real quality, 
grapes are the same to me;
either fresh or made into wine, 
the thought of Grapes is divine. 


Once or twice a year the churchyard becomes a makeshift 
market (talipapa), an acceptable part of culture - Christian 
and non-Christianm - here and abroad 

Church yard a market place 
once drew Christ's ire;
worship sans sublime
 and its essence divine.

Cotton candy, a favorite of children.  Wait till you see 
them wear a patch of beard of Santa Claus.  

Cotton candy meets the morning sun,
the maker a transient family
moving from town to town like gypsy
on the road to somewhere bound.  

   
 
Religious items all.  Faith is a great stimulus of art and trade. 

If the Renaissance grew with the Church, 
drew the world out of the Dark Age;
a second renewal we need today to save
our world from the cold and rage.  

The ambiance of a fair is not all about the wares to sell; 
it is the seller, like "the singer and not the song." 

Beauties in the fair with wares to sell:
rosary and jewelry as well;
trade an art indeed, the touch, the appeal,
of these threesome fair.    

Ingenuity at the grassroots at work. Mobile refreshment - 
a choice of flavor and color, quenching thirst in an instant. 

Take the backseat softdrinks, 
it's sago and gulaman time;
buko, melon and some color,
calling in a sweet chime. 


Candle offering at the shrine of San Vicente Ferrer. Pilgrims sought his divine intercession every Tuesday. His feast day is celebrated on the last Tuesday of April. 

What example your life brings to us, oh, St Vincent;
the pleasure of youth you renounced for the church;
highest in learning, with a gift of tongue and courage,
and we, your faithful, we simply beg for miracle. ~



Fusion - Path of Evolution

Sargassum fish cleverly intertwined and camouflaged, exhibiting combined  characteristics of plant, animal, and protist, the natural landscape under the sea, notwithstanding.   Paintings in acrylic on glass by the author (c. 2003)

Evolution is when the simple becomes complex,
     and the complex into intricate;
yet the intricate to complex, reverting into simple,
     when fail the process to replicate.

Evolution is forward and backward through time,
     simultaneous, spontaneous;
a explosion of diversity of all kinds imagined,
     in chains, webs and continuous. 

Evolution is untrodden, unguided, by chance
     in a million possibilities beyond
the eye or lens, and probing mind and will,
     in the depth of sea, or just around. 

Evolution is de-volution, shrinking, thinning -
     extinction by nature and by man - 
plant-animal fusing, moneran-protist pooling;
     prelude to a living world gone. ~

Pet Birds - are they?

Can you tell what these children are thinking about? Palm on check with 
serious expression shows the turning point of reason - "if you were in the 
shoes of someone." Would you be happy if you were inside a cage?

Pet birds in cages weaned from their nest,
to market, to market, but why the haste?
Children are waiting, urging their parents  
to buy them pets - but what a waste! 

A pet is a pet, and curiosity is not enough,
short live impulse, deep ignorance;
and poor child, the world is beyond him, 
to understand the difference.

Pet is freedom, pet is love, it is mutual;  
not in the cage but in trees singing,
a family and whole flock, it's a part of,
not money but freedom - or nothing. 

The children's faces are full of desire
but not of love's true expression;
Reverence for Life they must be taught;
we grownups, it's our mission. ~    

Birds in captivity is a great attraction to children. Here finches of different kinds are sold in small cages. Birds are the freest creatures.  They die in captivity by exhausting themselves to death trying to get out of their confines.   
Artificially colored maya appear unique, they may be mistaken for other species, perhaps rare to the innocent customer. Colors are harmful to both birds and man because of their lead content, among other compounds. 
Day old chicks and finches are made to appear unique and 
"beautiful" by dyeing and painting them with different designs. 


Colored day-old chicks are deceiving. It is not fair to the children, it is not fair to the Creator.
