Global trends that have been changing the way we live

Global trends that have been changing
the way we live

Dr Abe V Rotor
Living with Nature School on Blog [avrotor.blogspot.com]

"They always say time changes things, but you actually have to change them yourself," -  Andy Warhol

Global Warming, and Shrinking Nature, paintings by AVR 2015

1. Shrinking Nature - displacement of natural habitats with man-made settlements, wildlife is vanishing both in areas and biological diversity. Nature reserves cannot compensate for such loss, and will never be able to bring about ecological balance as a whole. "It is no longer us against Nature, instead it's we who decide what nature is and what it will be." says Paul Crutzen, Nobel Prize Awardee.

2. Stressful modern living - the higher the status the more stressful life is. The social ladder takes us to the syndrome posed by Paulas'Hope for the Flowers. There is really nothing up there, but a stressful life at the apex of society. The stressors affecting the poor are different from those in higher society. Those suffering of high-status stress find it more difficult to adjust than their counterpart in lower society.

3. Loss of privacy - Yet we always strive to retain our privacy even in public. No way: the computer has all the info about us - true or not; our relationships on various levels, more so with our public image. Hidden cameras are everywhere, on the other hand we too, intrude into the privacy of others. GPS gives us information about places, with minute details, often intruding to one's privacy similar to trespassing.

4. Aging gracefully and Niche Aging - Forget conventional wisdom; gray-haired societies aren't a problem. Longevity is increasing all over the world: the average age of a Japanese is 78 years with America following at its heels with 75 or 76 years. We are quite close to China with at least 70 years. Science and technology, socio-cultural and economic opportunities make ageing a privilege today.

In an article - Niche Aging, author Harriet Barovick said, "...the generic settlement model is starting to give way to what developers are calling affinity housing - niche communities where people as they advance in age opt to grow old alongside others who share a specific interest. Niche living is the latest step in the evolution of the planned retirement community.

5. "Immortal" Food - Food that virtually last forever (by increasing the shelf life), while there is a current trend which is the opposite. Go natural - food, clothing, energy, housing, and practically anything we eat and use everyday. (See article, Living Naturally, in this Blog)
"The people who are crazy enough to think they can change the world are the ones who do," -  Steve Jobs

6. Black Irony - Blackness has many connotations and implications - principally, historical and religious. Black means race, hell, disease, death, hopelessness, discrimination. But all these cannot  be grossly weighed as negative or destructive. Today when we talk of black we may be referring to the colored athletes who dominate many sports, great leaders of movements like Wangari who planted millions of trees in Kenya, and not to look far, former President Obama of the US, and the living hero of South Africa, Nelson Mandela. Racial discrimination - racism and apartheid - may soon be a thing of the past. It is because man is created equal beneath their skin, and in fact, by circumstance, the colored races have proved superiority over the non-colored: in schools, scientific discoveries, business, technology - name it and you have a colored standing out.
7. "Handprints, not Footprints" - a more encouraging way to conceptualize our impact in our handprints; the sum of all the reductions we make in our footprints." 
Eye of a dying coral as a result of global warming and pollution by AV Rotor 2005

Says the brainchild of this idea, a Harvard professor. We can reduce the impact of living against the environment - less CO2, less CFC, less non-biodegradables and other synthetics, less pesticides, etc. On the other side of the equation would be the number of trees we plant, our savings on electricity and water. Lesser pollutants, if not arresting pollution itself - and the like.
8. "Your head is in the cloud" - The best way to explain this is in the article written by Annie Murphy Paul. To quote: "Inundated by more information that we can possibly hold in our heads, we're increasingly handing off the job of remembering to search engines and smart phones." Never mind memorizing the multiplication table, or Mendeleev's Periodic Table of Elements. Spelling of a word, its homonym, antonym? Check it out on the computer. Presto! it will correct the word automatically. Search Love, and it comes in a thousand-and-one definitions. Assignment? Search, download, print, submit - just don't forget to place your name. Psychologists are back to the drawing board about learning. They have proposed a new term - transactive memory, a prelude to blending natural and artificial intelligence.

9. The rise of Nones - Nones are people who have no religious affiliation. More and more people are dissociating from organized religions, a kind of freedom to feel more devoted to God, of moving away from the scandals of the church, and money-making religions . For most, they are not rejecting God. They are rejecting organized religion as being rigid and dogmatic. However, a survey in the US showed that spiritual connection and community hasn't be severed by this new trend. Forty percent (40%) of the unaffiliated are fairly religious, and many of them are still hoping to eventually find the right religious home.

10. Living alone is the new norm - Solitary living is spreading all over the world. It is the biggest social change that has been long neglected. Living solo is highest in Sweden (47%), followed by Britain (37%). Following the list in decreasing order are Japan, Italy, US, Canada, Russia, South Africa, Kenya, and Brazil (10%). Living alone helps people pursue sacred modern values - individual freedom, personal control and self realization. In Lonely American, however, Harvard psychiatrists warn of increased aloneness and the movement toward greater social isolation, which are detrimental to health and happiness to the person, and in the long run, to the community and nation.

11. Common Wealth - National interests aren't what they used to be. Our survival requires global solutions. The defining challenge of the 21st century will be to face the reality that humanity shares a common fate on a crowded planet. Global warming, acid rain, El Niño, don't know political boundaries.

12. The End of Customer Service - With self-service technology, you'll never have to see a clerk again. It is an era of self-service - from filling up gas to banking to food service. Swipe your ID card to enter an office or a school campus. Credit cards abound, so with many kinds of coupons, all self service.

13. The Post-Movie-Star Era. Get ready for more films in which the leading man is not "he" but "Who?" Goodbye James Dean, Marilyn Monroe, Marlon Brando, Fernando Poe Jr. Welcome Nemo in Finding Nemo, Xi in Gods Must be Crazy.

14. Reverse Radicalism . Want to stop terrorism? Start talking to terrorists who stop themselves. Conflicts arising from radicalism can be settled through peaceful rather than by bloody means.
"I alone cannot change the world, but I can cast a stone across the waters to create many ripples," -  Mother Teresa.
15. Kitchen Chemistry . Why the squishy art of cooking is giving way to cold, hard science? There are specialized courses in culinary art, with the chef as central figure with a degree. Home economics has grown into Hotel and Restaurant Management.

16. Geoengineering . Messing with Nature caused global warming. Messing with it more might fix it. Can we ignite a volcano to cool the earth like the eruption of Mt Pinatubo did twenty five years ago? Scientists believe we can divert an approaching typhoon out of its path. Better still abort it at its early stage.

17.Curing the "Dutch Disease." How resource-rich nations can unravel the paradox of plenty. It's true, oil-rich nations in the Middle East - and Holland, and lately Nigeria, where the term was developed - are not growing fast in terms of Gross Domestic Products (GDP). Now compare this is non-oil rich nations like China and Vietnam, which are growing close to 10 percent annually in GDP.

18. Women's Work. Tapping the female entrepreneurial; spirit can pay big dividends. Women's Lib brought the female species at par - if not excel - with its counterpart. More and more women are occupying high positions in government and industries. Women may soon have higher literacy rates than men.

19. Beyond the Olympics. Coming: Constant TV coverage of global sporting events. Boxing grew into various titles, football games in various tournaments fill the TV screen. New sports and games are coming out.

20. Jobs Are the New Assets. A sampling of fast-growing occupations - Actuaries, financial analyst, computer programmer, fitness trainer, biophysicists, translators, manicurists, marriage counselors, radiologists. Need a design for your product? Give  it to an IT graduate with a background in design. Need a kind of product or service not found in the mall or supermarket, search the Internet. Entrepreneurs have taken over much of the functions of big business. Unemployment has given rise to this new breed - the entrepreneurs.

21. Recycling the Suburbs. Environmentalists will celebrate the demise of sprawling suburbs, which left national addicted to cars. Infrastructures will be converted in favor of "green", town centers, public libraries, museums, sports centers, parks. Notice the gas stations along NLEX and South Road, they have transformed into a complex where motorists can enjoy their brief stopover. More and more countries are imposing regulation to green the cities, from sidewalks to rooftops. Hanging Gardens of Babylon, anyone?  If this was one of the wonders of the ancient world, why certainly we can make a replicate - perhaps a bigger one - given all our modern technology and enormous available capital.

22. The New Calvinism. More moderate evangelicals are exploring cures for doctrinal drift, offering some assurance to "a lot of young people growing up in sub-cultures of brokenness, divorce, drugs, sexual temptations, etc."

23. Reinstating the Interstate, the Superhighways. These are becoming a new network of light rail and "smart power" electric grid. This is the alternative to car culture that thrives on fossil fuel and promotes suburban sprawl.

24. Amortality - "non-moral sensitive" or "neutral morality' - whatever you may call it, this thinking has revolutionized our attitudes toward age. There are people who "refuse to grow old," people who wish to be resurrected from his cryonized corpse.
Our Dying Earth becoming virtually a fossil planet, painting by the author

25. Africa , Business Destination. Next "economic miracle" is in the black continent. Actually it has began stirring the economic consciousness of investors and developers.

26. The Rent-a-Country. Corporate Farming, an approach pioneered by the Philippines in the 60's and 70s, is now adopted by giant companies to farm whole valleys, provinces, island, of countries other than their own. Call it neo-colonialism, - these are food contracts, the latest new green revolution, more reliable food security.

27. Biobanks. Safe deposits - freezers full of tissues for transplants, cryotude for blood samples, liquid nitrogen storage for sperms and eggs, test-tube baby laboratories and clinics. Welcome, surrogate motherhood, post-menopausal technology, in-situ cloning, multiple birth technology, and the like.

28. Survival Stores. Sensible shops selling solar panels, electric bicycles, power generators, energy food bars, portable windmill, etc. Attributes: living off the grid, smart recycling, sustainability, consume less, self-sufficiency, basic+ useful, durable lifetime guarantee, hip + cool community, independent, responsible, co-op, brand-free, out of the oven, goodness-driven, health fitness, meditation, bartering, sharing, socialistic capitalism.

29. Ecological Intelligence. There are guidelines now available to judge products on their social and environmental impact. This is new culture characterized by environment-consciousness, environment-friendliness. Here life-cycle assessment and clean-up corporate ecology become an obligation. We are going back - happily and beautifully to a simple and natural lifestyle.

30. Ecomigration - As global warming continues and the sea level rises more and more low lying areas will be swallowed up by the sea. Before this happens, people will have to move to safer grounds. This phenomenon is happening to many island in the Pacific, among them the Kiribati and Micronesia groups of islands.

USAPANG BAYAN: The Unknown Heroes in Our Times

USAPANG BAYAN 2-3 pm Nov 28, 2025

Bonifacio Day November 30, 2025

   The Unknown Heroes in Our Times 

Little do we know of the unknown great man:
the Unknown Soldier -
unknown doctor, unknown teacher
farmer, entrepreneur, worker,
old man, child, father, housewife 
the unknown in other fields of life.

Catholic priests organized a “voluntary” procession on Sunday, culminating in a solemn rally at the historic Edsa Shrine to express their stance against corruption and promote the nationwide Nov. 30 protest amid the multibillion-peso flood control scandal hounding the government. The protest coincided with the Feast of Christ the King, the last Sunday marking the end of the current Catholic liturgical cycle. The new liturgical year begins on Nov. 30, which also aligns with another nationwide protest as part of the Trillion Peso March, which started on Sept. 21. Internet

Bonifacio Day is a Philippine national holiday celebrated annually on November 30 to commemorate the birth of Andrés Bonifacio, the "Father of the Philippine Revolution" and founder of the Katipunan. It is a non-working holiday for public and private sectors, honoring his bravery and contributions to the country's fight for independence from Spain.

Make your own personal reflection of your favorite hero or heroine on a regular bond, in any style, 500 words more or less. Reflection brings out the inner person in you, like the inner eye of Heller Keller, the Little Prince of Antoine de Saint-Exupery', idealism of Longfellow and Alexander Pope, meditation in Michelangelo's Pieta, the mysticism of Venus de Milo, enigma of wildlife in Rousseau's painting, inner ear of Beethoven, waning light in Claude Monet's Waterlily Pond. We suggest Rizal's closeness to the people while in exile for 4 years in exile in Dapitan,  Andres Bonifacio's nationalism as founder and leader of KKK, Ramon Magsaysay as man of the masses. (Dr Abe V Rotor Living with Nature - School on Blog)

I invite our viewers to this exercise. You may find this useful in retreats and seminars, specially on leadership, and in the fields of history, arts, theology,  philosophy, and humanities.

All of us - we have the capacity to be great.
Bringing up our children to become good citizens,
being Samaritan on a lonely road,
embracing a returning Prodigal Son, 
plugging a hole in the dike like the boy who saved Holland from the sea,
or living life the best way we can that makes other lives better.

These and countless deeds make us great,
and if in this or that little way we may fall short of it,
then each and everyone of us putting each small deed together,
makes the greatest deed ever,
for the greatest thing humans can do is collective goodness –
the key to true unity and harmony,
and peace on earth. ~

 Andres Bonifacio  
"Father of the Philippine Revolution"

Andres Bonifacio is known as the "Father of the Philippine Revolution" for founding the secret society Katipunan, which initiated the revolution against Spanish colonial rule. He was born in Tondo, Manila, on November 30, 1863, and led the Katipunan in its fight for Philippine independence.

Founder of the Katipunan:
In 1892, Bonifacio and others formed the Katipunan (Kataas-taasang, Kagalang-galangang Katipunan ng mga Anak ng Bayan) to secure independence from Spain through armed revolt.

Revolutionary leader:
As the "Supremo" (supreme leader) of the Katipunan, he organized and led the initial stages of the revolution.

Key actions:
Bonifacio famously led the "Cry of Pugad Lawin" where revolutionaries tore up their community tax certificates to symbolize their refusal to pay taxes to Spain, a pivotal moment that sparked the revolution.

Legacy:
Despite his tragic execution in 1897, his role in igniting the revolution and founding the Katipunan earned him the title "Father of the Philippine Revolution". AI Overview

Have you seen a kugtong or giant lapu-lapu?

  Have you seen a kugtong or giant lapu-lapu?

Dr Abe V Rotor
"If there is a Coelacanth long thought to have been extinct that lives in the craggy bottom of Madagascar Sea, we have our own kugtong, the biggest coral dwelling fish." (AVR) 

Giant Lapu-lapu in its abode, section of a wall mural by Dr AV Rotor 
in his city residence, QC.  Closeup photo of a blue lapu-lapu.

In the craggy depth of the sea lies a monster - the giant lapu-lapu or grouper. Fishermen in the area respect the niche of this benthic creature. They tell stories of missing pets and fishermen, of mysterious encounters that turn the sea inside out, a battle between a kugtong and a giant squid or whale. These are stories of fishermen and are often exaggerated. 

At SEAFDEC (Southeast Asia Fisheries Development Center) along the coast of Iloilo, lapulapu is cultured and studied in captivity.  The making of a giant is evident in one of these photos. The longevity of the fish may be the same as that of human, and a full grown has a mouth so huge it can engulf its prey whole and alive.

I saw two giant lapu-lapu (kugtong) in Sablayan Occidental Mindoro caught by local fishermen sometime in 1982. I had been hearing kugtong since childhood, a threat to fishermen and picnickers because it could swallow a whole human being, and here with my own eyes the kugtong in Lola Basiang’s story is true after all. So huge are these overgrown lapu-lapu that two men could hardly carry one of them with a bamboo pole on their shoulders.  A third man had to lift its tail from the ground as they inched their way to a waiting vehicle. I examined the fish; its body is coarse and shaggy, covered with seaweeds and barnacles, and had lost all semblance of the favorite lapu-lapu on our dining table. But this makes a perfect camouflage that suits the predatory habit of this benthic fish.  By the way, it is the female lapu-lapu that attains this enormous size.  The male is a diminutive partner permanently attached to her body, indeed a very special kind of relationship in the animal world.    

There is a story about a kugtong that lived under the old pier of San Fernando, La Union. For a long time the strange fish was feared by the residents and many animals around had mysteriously disappeared.  Then the local fishermen decided to catch it with a big hook luring the fish with a live piglet as bait.  The fish took it and struggled until it was finally subdued.  It was hauled by many men and if the story is accurate it took a six-by-six truck to transport it.

There are giants in the deep.  After the tsunami in 2004 that hit the Indian Ocean, by coincidence I saw giant squids measuring 3 feet long being sold at the SM Fairview supermarket. I surmise that these were flushed out from their deep dwellings and landed in the fisherman’s net when the calamity struck. I remember the giant squid that almost sank Captain Nemo’s submarine in Jules Verne’s “Twenty Thousand Leagues Under the Sea.”  

There is mystery in the biology of lapu-lapu- or grouper, as it is known worldwide. Groupers are hermaphroditic, which means that sex switch from male to female and vice versa. The young are predominantly female but transform into males as they grow to about a kilogram in a year, remaining adolescent until they reach three kilos. From here they become females. But wait. When they are about 10 to 12 kg they turn to males and grow very, very big. Lengths over a meter and weights up to 100 kg are not uncommon.
A 64-kg lapu-lapu caught in Siaton, Negros Oriental Internet

A newspaper reported a 396.8 pound grouper caught off the waters near Pulau Sembilan in the Straits of Malacca in 2008. Shenzhen newspaper reported that a 1.8 meter grouper swallowed a 1.0 meter whitetip reef shark at the Fuzhou Sea World aquarium.

I asked my friend Dr. Anselmo S Cabigan, a fellow biologist. “What is really the sex of a full grown kugtong, such as those I found in Mindoro?”

In my research it is male. The male is larger and wilder than the female, and I use as analogy the bull to the cow, rooster to hen, peacock to peahen, lion to lioness.

Dr Cabigan thinks it otherwise. The female is larger, in fact much larger, that the male is virtually a remora-size creature attached to the female. I imagine the huge size of the queen termite as compared to the tiny king termite. The enigma of the grouper, considering its diversity, and worldwide distribution could yet reveal other amazing facts about the kugtong. Among the institutions working on the kugtong is SEAFDEC, which admits its biology and ecology remain a mystery.

 At least we are sure the kugtong does exist. ~

The KRAKEN exists - do you believe it?

  The KRAKEN exists - do you believe it?

Giant and grotesque creatures of the deep are emerging lately with the series of earthquakes occurring in different parts of the world. People are asking whether their emergence is prediction or aftermath of force majeure. Exobiology is searching and studying life in the cosmic and abyss. Among these mysterious giants known largely in fiction are sunfish, oarfish, and the legendary kraken - monstrous colossal squid or octopus.

Dr Abe V Rotor
Living with Nature - School on Blog [avrotor.blogspot.com]

Author displays rare specimen, giant in size compared to commercial squid.
  
Nearly six kilos, and 1.5 meters long, this giant squid was flushed out of the deep off the coast of Pasacao, Camarines Sur, following a mild earthquake that shook the area. It is one of several others,  some weighing more than ten kilos. Their tough and thick skin protects them from extreme pressure at hundreds of meters on the ocean floor where few creatures can tolerate. Here they prey on deep fish and marine organisms such as crustaceans and other mollusks.  They rid of the sea of aging and injured organisms as sharks do on the surface of the sea. 


In Jules Verne's novel, Twenty Thousand Leagues under the Sea, the giant sea monster is an octopus (left photo)  so huge it nearly wrecked the prototype submarine Nautilus of Captain Nemo. High voltage electricity was applied to release the monster's crushing grip. The other picture is the legendary kraken described by sailors as far back as in ancient Greece. 

In John Steinbeck's less popular book, "Where have all the sardines gone?" there is a photo of a giant squid washed ashore along San Francisco, California.  From the looks of the B and W photograph the creature could weigh half a ton. This is not an isolated case; several specimens were caught or discovered as carcasses in many parts of the world. 

Just after the tsunami that occurred in the Indian Ocean in the early part of this decade, my son, Marlo and I saw two giant squids being sold in a wet market in Fairview, QC. They are twice bigger than the specimen shown in the first photo. 

Indeed monsters lurk in the dark, deep ocean.  And considering the fact that the earth's surface is three-fourth ocean with an average depth of nearly four kilometers, plunging to more than twelve kilometers in Marianas and Philippine Deep, there are indeed countless of unimaginable monsters down there.  They continue to build legends that became part of mythology, fiction stories, and lately, scientific discoveries.~

Corn or Maize – World’s Emerging Number One Crop

 Corn or Maize – World’s Emerging Number One Crop

Dr Abe V Rotor
Living with Nature - School on Blog 

  
Thai corn is exported to the Philippines. Changmai Thailand 

Corn or Maize (Zea mays L) is the most important cereal in the world today, surpassing wheat and rice. It is because corn has a wide range of adaptability, from the tropics to the temperate and high elevation areas. And it comes in many varieties and cultivars - natural, hybrid and genetically modified - thus widening its cultivation and uses, including the production of medicine and biofuel.

What makes corn No.1?  Here are important reasons.  
  1. Yellow corn is the most important feed ingredient for poultry and livestock (up to 80 percent). The yellow pigment - carotene and xanthophyll group is rich in vitamins and it imparts attractive color to meat and eggs. Calories, protein and other nutrients in yellow corn compensate to a large extent for lack of costly feed supplement like fish meal.  
  1. Corn's response to increasing input (fertilizer) is higher than that of wheat or rice, reaching up to 12 MT per hectare, twice or more than either of the two staple crops. This means the ratio of  input and yield (Nitrogen:Grain) is wider, translated into higher productivity and income.  
  1. Inter-cropping of corn with legumes, like peanut and bean (e.g. mungbean, cowpea), is key to sustainable productivity: corn fixes Carbon (C4) which is shared with the companion crop (legume), while the latter being a Nitogen fixer  provides the needed nitrates (NO3) to both crops. After the crop season, the residual fixed compounds are kept in the soil which will be used by the next crop or crops.  
  1. Three Sisters cropping system is a modification of the dual inter-cropping, though practiced since ancient times by Mesoamerican farmers - the Aztecs, Mayans, Incas, Olmecs -  by planting three crops at the same time: corn (C-fixer), bean (N-fixer), and squash which controls weeds and serves as mulch to reduce soil moisture evaporation, and soil nutrient loss due to ultraviolet rays. We can only imagine the ingenuity of these farmers centuries ago, albeit scientific explanation that accompanied their skill and art.   
  1. Corn offers different subspecies, varieties and cultivars to meet cultural preferences, food preparations, and other uses.
    Flour corn — Zea mays var. amylacea
·        Popcorn — Zea mays var. everta
·        Dent corn  — Zea mays var. indentata
·        Flint corn — Zea mays var. indurata
·        Sweet corn — Zea mays var. saccharata and Zea mays var. rugosa
·        Waxy corn — Zea mays var. ceratina
·        Amylomaize — Zea mays
·        Pod corn — Zea mays var. tunicata Larrañaga ex A. St. Hil.
·        Striped maize — Zea mays var. japonica. 

These categories have been modified through DNA analysis into multi-variable classification adopted by many research centers, particularly CIMMYT (Centro Internacional de Mejoramiento del Maiz y Trigo) the world's leading corn center where, like IRRI for rice, keeps a germplasm bank for corn gathered from all over the world. Corn is perhaps one of the most studied crops, genetic studies on its genome has been completed. A Nobel prize was awarded to a certain  Barbara McClintock who discovered knob markers to validate her theory of "jumping genes" which is key to modern genetic taxonomic study of crop. 

6. Genetically modified corn is the most widely cultivated GMO in the world, with the US and Canada planting more than three-fourth of their land area to GM corn.The Philippines has recently joined other countries in GMO research and cultivation in spite of heavy objections.  It is estimated than a third of the world's corn crop is GMO.  Which means that people are eating and indirectly GM corn unaware and without warning. In September 2000, up to $50 million worth of Taco Bell's shells were recalled from its restaurants as well as supermarkets. The shells contained genetically modified corn that was unfit for human consumption by the Food and Drug Administration.(Wikipedia, underscore retained)

7. Corn is a major source of fuel. There is controversy as to whether corn as fuel is more important than human food particularly in developing countries. Whereas, in the US corn, being grown on large commercial scale, is not only the chief feed for the animal industry, but as source of alternative fuel to reduce dependence on fossil fuels.
The US is the world’s top producer of ethanol from corn with a production target of 35 billion US gallons (130,000,000 m3) of biofuels by 2017, ethanol production will grow to 7 billion US gallons (26,000,000 m3) by 2010, up from 4.5 billion in 2006, boosting ethanol's share of maize demand in the U.S. from 22.6 percent to 36.1 percent.

Corn is widely used in Germany as a feedstock for biogas plants. Here the maize is harvested, shredded then placed in silage clamps from which it is fed into the biogas plants. This process makes use of the whole plant rather than simply using the kernels as in the production of fuel ethanol.

In developing countries on the other hand "feed maize" is being used increasingly for heating on specially designed stoves similar to firewood stoves. Corn cobs are also used as a biomass fuel source.

10.There are many other uses of corn such as

·      .o  Corn as alternative medicine is an age long practice.  Water from boiled corn is taken with or without sugar has diuretic properties. It is recommended in folk medicine for kidney problems.  

·         Starch from maize can also be made into plastics, fabrics, adhesives, and many other chemical products.

·         The corn steep liquor, a plentiful watery byproduct of maize wet milling process, is widely used in the biochemical industry and research as a culture medium to grow many kinds of microorganisms.

·         Chrysanthemin is found in purple corn and is used as a food coloring.

·         Corn as green fodder is popular on the farm for working animals, particularly carabao and bullock.  To improve digestibility and palatability corn fodder is first made into silage, rather than fed in dried form. We do not practice silage in the Philippines, unlike other countries where fodder is not available throughout the year.

·         Maize kernels can be used in place of sand in a sandbox  enclosure for children's play.
 Corn cob powder is a substitute of talc in the manufacture of talcum powder for the face, body, and babies. Corn cob powder is safer because it is organic, unlike talc which is a mineral.  Talcum powder is made from talc, a mineral made up mainly of Magnesium and Silicon, and in its natural state may contain asbestos which causes cancer of the lungs - and ovarian cancer in the case of talcum dependent women.
