Enigma of the Coral Reef

Enigma of the Coral Reef
No ecosystem in the world is more vast, open
and free than the coral reef.

                Enigma of the Coral Reef in acrylic paintings by Dr Abe V Rotor
Don a snorkel and a new world unfolds - the coral reef.

It is a forest under the sea, the counterpart of the forest we know on land. There are also equivalent trees like the giant Sargassum that grows several feet long; shrubs like the branching Gracillaria; cacti like the broad Padina; annuals like spongy Codium. Together with sea grasses, these seaweeds form multi-storey greenery at varying depths the same way forests have the features of mountains, hills, caverns and cliffs.

The animals that live here are more varied and colorful than those on land, mimicking the prism of sunlight in water with all the splendor of the rainbow. There are fishes that are distinctly bright colored, and at night exude phosphorescence like neon lights. They borrow the shape of their surroundings, the corals and seaweeds, for both protection and aggression - all these are adaptations for survival.

On the coral reef food chains have more links, so to speak, and food webs more intricate, as both residents and transient organisms interact. No ecosystem in the world is more vast, open and free than the coral reef. It is also the most lavish. Even beauty itself. Living things and all their ornaments are irresistible to be awed and respected, holding an enigma that expands our imagination to fantasy that lures us to the sea and to love to fish and comb the reefs all day. To write poetry - and to paint. ~

Art Evolution in the Garden

Art Evolution in the Garden
 Dr Abe V Rotor

"Freedom with nature rests on oneness with creation." - avr

Cactus bonsai, dwarf Agave and overhanging striated Oregano grouped in a recycled PET container make a miniature garden. The setup gets occasional watering and sunlight exposure on weekly maintenance. Mural background lends a three-dimensional effect to heighten a make-believe nature scene in the receiving area, porch or hallway, as may be preferred. Artwork and mural by the author.

"Man-Heaven-and-Earth," in this order,
  a rule in garden and floral arrangement;
  man is first, though humbly in-between;
  because beauty lies in his own judgment.  
    
Hanging chime plays with the breeze at the doorway of the Center.  Nature painting as background adds quaintness, and enhances the ambiance of the place.  A wooden head of a deer with real anthers has a strong and urgent message of wildlife conservation.

Natural curtain adds coolness and aesthetic beauty, besides increasing Oxygen level around and through the window. Ornamental plants also serve as buffer against noise, radiation and dust, and repellant against pest as well.

A green house sans walls
    of concrete like prison;
freedom with nature rests
    on oneness with creation

House guest delights in seeing artifacts of happy childhood like slingshot, fishing rod and basket, sungka, spinning top, bow and arrow, dream catcher, and many nostalgic items left behind as one grows into an adult, more so when he or she reaches old age. 

"You can grow up, and get wiser, and stay true to yourself, there's a difference between changing everything about you, and adding things to the same you, to make a better you... You can still be a child at heart, but be mature at the same time... There's a time and place for everything... Growing older, just helps you realize what those times are." - IcySky, Growing up

ASSIGNMENT:  List down the toys and games you played with as a kid, your "favorite things," photos and images, art works, tools, paraphernalia, and many others you may have long kept and virtually forgotten.  Build a home museum with members of your family, relatives and friends.  You'll be surprised to discover a treasure that keeps childhood alive through the years. There  is a saying, "A thing of beauty is a boy forever." (From "A thing of beauty is a joy forever." - John Keats)

Live Healthier and Longer with Natural Food

 Live Healthier and Longer with Natural Food

Eat foods grown under natural conditions, rather than those grown and processed with the use of chemicals. And no Frankenfood (GMO), please. 

Dr Abe V Rotor

                                      Vegetarian's barbecue - all naturally grown.

It is not enough that we produce food. We must produce food that ensure good health, reduce risks to diseases and ailments, and prolong life. We must produce food that also insures the health of our environment and the stability of the ecological system.
While science and technology continue to explore new ways to increase food supply with genetic engineering, people are yearning for organic food – or naturally grown food.

Here are issues raised by the proponents of organic farming.

1. Many ailments and abnormalities are traced to the food we take. Cancer for instance, is often related to carcinogenic substances. High uric acid leads to kidney trouble. High choles¬terol and high sugar levels are associated with high blood pressure and diabetes. Aftatoxin causes cirrhosis of the liver. Ulcers are food-related, as are many allergies.

2. Proper nutrition and balanced diet can be attained by eating the right kind and amount of natural food without fortification with vitamins and minerals, and other forms of altering food value. Thus there is no need to process food unless it is really necessary. Fresh foods – vegetables, fish, and the like – are still the best. And why modify the genetic composition of crops and animals? Leave that to nature. Nature knows best.

3. Taking excess foods rich in animal fat and protein, and foods high in calories foods has predisposed many people to overweight conditions. Gaining unnecessary weight leads obesity now an epidemic sweeping many countries today particularly in cities where there is a proliferation of fast foods and junk foods. Or simply there is too much of the “good life” – excess in food and pleasure. In the US today one out of five Americans is an obese.

4. There are natural substances that keep our body always alert to fend off stress due to overwork and diseases. They are known as probiotics. We get probiotics from fruits and vegetables. We also get them from seaweeds, mushrooms, yoghurt, algae such as Chlorella, and cyanobacteria such as Spirulina. And there are many more sources that occur in nature. We are beginning to realize that eating foods rich in probiotics and antibiotics (substances that directly kill germs) makes us healthier and live longer.

These are the rules set by the advocates of natural farming.

1. It is always better to eat foods grown under natural conditions than those developed with the use of chemicals.

This statement can be captured with one term "natural food". All over the world this is a label found in food grown without chemicals. People are afraid of becoming ill because of chemicals introduced into the food. There are banned pesticides still in used such as methyl parathion, endosulfan, DDT, BHC, among others. These are also harmful to all living organisms and to the environment.

2. People are avoiding harmful residues of antibiotics and pesticides.
Poultry, hogs and cattle are given high levels of antibiotics to safeguard the animals from diseases. As a result the antibiotics are passed on to the consumers. Unless we are ill, the body does not need supplemental antibiotics. We have adequate natural sources. Every time we eat commercial eggs, chicken, pork chop, steak, and the like, we are taking in antibiotics which accumulate in our body, shutting off our immune systems, punishing our kidney and liver. To many people, antibiotics cause allergic reactions.

3. People are getting scared of food contaminated by radiation. Nuclear reactors are being built in many countries as a fallback to fossil fuel. After the Chernobyl nuclear plant meltdown in Russia, and that of the Three-Miles Island nuclear plant in the US, people have become wary about the consequences of fallout. A trace of radiation can be absorbed by grass in the pasture, finds its way to milk, then to infants. Radiation can remain active for hundreds of years. People are still dying today in Nagasaki and Hiroshima, more than fifty years since the bombing of the two cities with the first atomic bomb.

4. Be aware of the deleterious effects of toxic metals, such as lead, mercury and cadmium. These find their way through the food chain and ultimately reach humans. They escape to the air and enter our lungs, as in the case of dusts from old paints. Since they are in soluble compounds, they are easily absorbed by plants and animals. Kangkong for example absorbs lead. Tuna has high mercury in its tissues and liver. Cadmium from batteries is absorbed by crops.

The simpler your food is cooked, the better.

5. People are becoming more conscious of the nutritional value of food rather than its packaging and presentation.
More and more people are shunning away from junk foods, in spite of their attractive packaging. Soft drinks have taken the backseat, courtesy of fruit juices and mineral water. People have even learned that different plant varieties have different levels of food value. Beans grown on naturally fertile soil have higher calorie and protein content than those grown on poor soil, or with chemical fertilizers. This is also true with animals. Animals raised with proper nutrition give meat, milk and eggs with higher protein, minerals notwithstanding.

6. Freshness is the primordial rule in choosing a perishable food.
There is no substitute to freshness. While freshness is a function of efficient handling and marketing, the farmer must enhance farm-to-market freshness. By keeping his standing plants healthy, his produce will stay longer on the shelf life. Products that are free from pest and diseases also stay fresher and longer. Too much water or fertilizer reduces shelf life of the commodity.

Eat fresh fruits - avoid processed ones.

7. Food processing must be efficient and safe.
Food processing, such as drying, milling and manufacturing is key to higher profits. Whenever feasible, food must reach the table fresh. But processing is designed to lengthen the shelf life of perishable commodities. There are products that require processing before they are used. These food items include vanilla, coffee, cacao, wine and vinegar, soya, fish sauce and the like. Profits generated through processing are value-added to production.

8. Food must be free from pest and diseases.
By all means, food must be free from insects and pathogens. There are cases of food poisoning as a result of food deterioration, or contamination. Take salmonella and E. coli. Khapra beetle in grains may even cause death to animals. Weevils hasten the deterioration of the food.

9. Food preservation must ensure quality, and above all, safety.
Be aware of the fish that is stiff, yet looks fresh. It is easy to detect the odor of formalin. Salitre is harmful, so with vetsin or MSG (Monosodium glutamate). Too much salt (sodium) is not good to the body. Some puto makers add lye or sodium hydroxide to aid coagulation of the starch. We wary of sampaloc candies enticingly made red with shoe dye. The same diluted dye is used with ube manufacture to make it look like the real violet-colored tuber.

Watch out. the utensils you are using may contain lead, mercury, plastic compounds, aluminum oxide and other harmful substances.

10. Beware of Frankenfood - Food derived from GMOs (Genetically Modified Organisms). Many countries warn of the potential dangers of genetically modified food and food products. This move is not only to safeguard health, but also the environment. Genetically modified plants and animals – as well as bacteria, protists and even viruses – are now a threat to the natural gene pool, giving rise to a new kind of pollution - genetic pollution. Once a gene pool of a certain species is contaminated with a GMO genetic material Genetic pollution cannot be eliminated, even in subsequent generations. Thus, it also disturbs natural evolution.

Next time you go to market, remember these guidelines. Why not convert that idle lot to raise food that is safe to your health and the environment? That little corner could be the start of a new green revolution.~

Caulerpa or lato is now cultivated in fishponds where
conditions can be controlled, unlike in the open sea.

Green mussel or tahong absorbs toxic metals like lead
in polluted water. It is also dangerous to eat tahong
during red tide period. It may cause paralytic poisoning.
Be guided by DA-BFAR warnings on media.

Tree of Thorns and Beads

Artwork made of wild thorny cherry and rosary beads 
against a mural background. (5 ft tall)  AV Rotor 2025. 

One afternoon I saw a leafless cherry tree
     standing all alone is my home garden;
It's autumn, I said, yet monsoon wasn't over;
     I imagined a scene of the lost Eden.

Days passed and my tree remained leafless; 
     its menacing thorns looked like its crown;
I imagined how a proud tree looks in its prime,
     and a bright red rose in the morning sun. 

In the sunset years of life, the cherry and rose,
     carry on their lesson in sweet memory,
their thorns adorned with gems and medals,
     as symbol of man's piety and glory.   

             "A rose's rarest essence lives in the thorn."- Rumi -

* In life, thorns symbolize hardships, challenges, pain, and suffering, contrasting with the beauty of roses (joy/success), teaching resilience, humility, and growth, often representing necessary obstacles that strengthen faith, provide course correction, or test our character, as seen in biblical and philosophical contexts. They signify that struggles make positive moments more meaningful and can be catalysts for spiritual or personal development. AI Overview
