Breathe and Die Asbestos By Dr. Michael A. Bengwayan, Ph.D. Environmental Science Earth Times





Breathe and Die Asbestos

Subic, Philippines (January 5, 2018) ---Alfonso Tabanyag, 65 has been looking forward to the birth of his first grandson. Donning his favorite Chicago Bulls cap, he stepped out to take a taxicab to the hospital where his daughter gave birth. Suddenly he felt being choked, his lung seemed bursting and he was gasping for air holding his chest.

Brought to the emergency room not far from the ward where his grandson lay sleeping, he was told he was suffering from severe Asbestosis, a killing phenomenon for people who have long been exposed to asbestos or its components.

Tabanyag is one of more than 1,000 worker-victims of Asbestosis in this once-sprawling US military base, who worked for 25 years insulating the facilities from dreaded military attacks that could make the base erupt into an inferno.

For Tabanyag, breathing from now on will be a struggle.

There are thousands more like him, says the International Labor Organization (ILO) who reported in its September labor international updates that cancer-causing asbestos and its particles continue to maim men, women and children alike worldwide.

It is urgently pushing for the adoption of more stringent standards on industrial uses of asbestos.

Fiber-Mineral the Only Kind
Asbestos is a fibrous mineral formerly used a great deal as heat and fire-resistant insulating material. This threadlike mineral fiber has more than 2,000 uses which is why many countries have not totally junked it.

From being fire resistant to good conductor of heat and electricity, ILO said it is probably found in almost 95 percent of all houses worldwide because it is a component of cement.

It is used in housing, fireproofing, and automobile parts especially as brake lining and gaskets, theater curtains, roofing, electrical insulation, caulking, cement pipes, floor tiles, and plastics. In manufacturing firms, it is used to insulate boilers, and as filters that resist chemicals.

As a mineral, asbestos is hydrated silicates from the mineral silica and comes from metamorphic rock. It was discovered in 1774 by Abraham G. Werner, a Mineralogist. It was used till 1931 before doctors noted the ill effects it causes to people.

Russia and Canada remain the biggest producers worldwide.

Asbestosis
In its September 2016 report, the ILO said that asbestos does not only cause Asbestosis, a serious lung disease, but also Bronchial Cancer and Mesothelioma (cancer of the Pleura and Peritoneus) which are fatal.

Asbestosis is a disease that blocks the lungs with thick fibrous tissues. Besides causing difficulty and shortness of breath, it causes swollen fingers and toes.

To those directly working with it like Tabanyag, asbestos causes Bronchogenic Cancer, the cancer of the bronchial tubes.

ILO also announced that cigarette-smoking workers who are exposed to asbestos have high rick to cancer.

People exposed to asbestos such as those working in asbestos mines, industrial facilities, insulation fabrication and military installations are the most likely to develop such diseases, ILO said.

According to Dr. Tony Smith, Deputy Editor of the British Medical Journal, asbestosis causes widespread scarring of the lungs and tends to progress even when exposure to it is discontinued.
The disease causes breathlessness and a dry cough eventually leading to severe disability and death.
Victims usually start experiencing asbestosis symptoms after seven to ten years of exposure.

Smith clarified that, even today, scientists do not know how asbestos causes disease.

Medical researchers though explain that fibers longer than 5 to 10 micrometers increase the risk of illness, he said.

An extremely short period of inhaling large amounts of asbestos fibers may result in Mesethelioma, he added.

Other Asbestos-Induced Diseases
Smith explained that mesothelioma is a result of a malignant tumor of the pleura or the peritoneum.
The Pleura is a membrane that surrounds the lungs while the Peritoneum is a membrane that lines the abdominal cavity and covers the abdominal organs.

He lamented that there is no treatment for the disease which usually leads to death within one or two years.

Another disease that arises from exposure to asbestos, the ILO reported, is Bilateral Diffuse Pleural Thickening wherein the outer and inner layers of the pleura become thickened and become calcified or “bony”. This causes fluid to accumulate in between the cavities and restricts the ability of the lungs to expand resulting in shortness of breath.

The American Society of Plastic and Reconstructive Surgeons bared that asbestos is also the cause of pleural plagues.

These are thickened tissues confined to the outer layer of the pleura. While this does not cause disability, it can develop into an asbestos-related disease.

Jekyll and Hyde
Occupationally, millions are exposed to inhalation of significant amounts of asbestos dust during the ordinary workday. This is because there is still a growing world production of asbestos.

Some 5 million tons were produced last year compared to only 675,000 tons in 1940, added the ILO.
While using asbestos for insulation got abated, the mineral is still vital in production of cement and as ingredient to some 1,000 other industrial products.

No technologically alternative materials can replace asbestos today, ILO admitted as it saves millions of lives when manufactured into fire protection and brake linings. But, it is also a threat especially to the health of industrial workers, thus dubbed “Dr. Jekyll and Mr. Hyde”.

The ILO recommends that governments should prescribe occupational exposure limits with corresponding testing measures, and that an international safety measure standard be adopted. Such measures must include dust control, constant monitoring of workers’ health, and the use of adequate protective clothes and masks.

Ultra Violet Radiation Now Causing World’s Amphibians to Go the Way of the Dodo By Dr. Michael A. Bengwayan, Ph. D., Environmental Science Environment News Network



Ultra Violet Radiation Now Causing  World’s Amphibians to Go the Way of the Dodo
By Dr. Michael A. Bengwayan, Ph. D., Environmental Science
Environment News Network

Baguio City, Philippines (Jan 3, 2018)—Anyone looking for a silver bullet that will explain all the amphibian deaths and declines in Asia and around the world, is going to be disappointed, scientists say.
Fourteen species of amphibians have vanished in Australia recently.  The golden toad is now extinct in Costa Rica, and five amphibians no longer exist in the United States. Amphibians are declining in Europe, Asia, South America and Africa.
Global declines of amphibians refer to the phenomenon of the population declines and even extinctions of amphibian species around the world. Assessments of the world’s amphibians  from 2004  to  2008 found that nearly a third of the known species of amphibians are globally threatened with extinction and that at least 42% of known amphibian species are experiencing population losses.
“This is an incredibly complex problem, a disturbing one and there’s no end in sight”,  scientist Vance T. Vredenburg,  of San Francisco State University, of San Francisco, California said.
It is now certain that multiple causes are contributing to the troubles of amphibians, said Vradenburg, and the lack of a single definite cause does not diminish the seriousness of this alarming ecological phenomenon.
 UV-B radiation, Pathogens Emerging Culprits
“At this point we can say that there are several causes of amphibian declines which include rising levels of UV-B radiation in sunlight, pathogens, pollutants, habitat destruction, introduced predators, pesticides, and most recently, fertilizers,” Vredenburg said.
“But the overall result is that this group of animals which has been around since the time of dinosaurs is now in serious decline around the world.  Ultra-violet rays coupled with pathogens and high nitrate levels are enough to cause amphibian deaths or deformities,” he ddded.
Vredenburg’s colleagues Kellie Whittaker, Michelle S Koo, and David B Wake of the University of California, Berkeley, CA, USA  authors of Global Declines of Amphibians said  the rapidity and extent of these declines, far more dramatic than those described for birds, mammals, or reptiles, forecast impending extinction of numerous amphibian species during the coming decades.
Increase in UV–B has been hypothesized to contribute to increased amphibian decline. Global atmospheric changes caused by anthropogenic activities are well documented and one result is a reduction of stratospheric ozone, leading to an increase in the amount of biologically damaging ultraviolet radiation (UV–B) reaching the Earth’s surface 
Unlike Vredenburg, they say however that the greatest threat is presented by a virulent fungal pathogen that is causing the infectious disease chytridiomycosis, which has decimated entire assemblages of amphibians worldwide. This pathogen, Batrachochytrium dendrobatidis, is responsible for what may well be the greatest disease-caused loss of biodiversity in recorded history, having caused population crashes or extinctions (often within a single year) of at least 200 species of frogs, even in relatively undisturbed, remote habitats, the  herpetologists said.
The American Association  for the Advancement of Sciences (AAAS) say amphibian immune defenses are being adversely being affected because of global warming and pollution. One  group of chytrid fungi that affects amphibians  is a parasite that feeds primarily on algae which often blooms in areas with excess nitrogen from farm runoff.
Extent of Amphibian Decline
The geographic extent of amphibian declines is worldwide.
The international Union for the Conservation of Nature (IUCN) says  the areas most strongly affected are located in Central and South America, the Caribbean, the wet tropics of eastern Australia , and western North America.
 The islands of the Caribbean and Pacific have some of the highest percentages (up to 100%) of endemic species that are threatened or endangered, but have relatively few species. 
Less is known about the status of species in Africa and Asia. But some species-rich countries have alarmingly high percentages of threatened and endangered species (e.g., 70% for Sri Lanka, based on the online resource IUCN 2010).
The authors of Global Declines of Amphibians emphasized the worldwide amphibian decline is multi-pronged. Deforestation, lake and pond draining and farming in amphibian-rich habitats worldwide are worsening the amphibian die-offs, they said.
Frogs  Most Threatened
Esteemed Philippine herpetologist Dr. Angel Alcala  of Silliman University says with the current rapid extermination of animals, plants and other species  the real "sixth mass extinction",  is the amphibian branch of the tree of life that is undergoing the most drastic pruning.
Of the 107 Philippine amphibians,  26 species  are Highly Vulnerable, 48 species  are Moderately Vulnerable, 27 species  are Vulnerable, and 6 species are Least Vulnerable to climate change , Dr. Alcala said.
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 848 endangered amphibian species,  13% of all evaluated amphibian species are listed as endangered.
Frogs are the most threatened, IUCN reported climate change, habitat destruction and disease could drive more than half of all Europe's frogs, toads and newts to extinction within 40 years.
These include water frogs, robber frogs, robust frogs, shrub frogs, forest frogs, rain frogs, cryptic frogs, true frogs, fleshbelly frogs, glass frogs,  litter frogs, screeching frogs, poison dart frogs, hemiprachtids, fork-tongued frogs, narrow-mouthed frogs, hylids, puddle frogs, reed frogs and ground frogs.
Frogs are more sensitive to climate change than other  amphibians because they exhibit habitat and microhabitat specialization and  that they are significantly less vagile. Many of the effects of climate change might be indirect, involving such factors as manifestations of disease or pathogen-host dynamics, and may involve interactions with other stressors.
Saving Frogs
To save some of the world’s frogs, the Declining Amphibian Task Force of the Smithsonian Institute is using methods borrowed from ornithology—including backyard pond observations and frog call counts modeled after breeding bird surveys—to help collect data needed to devise solutions.
Although some biologists view captive breeding as a last-resort conservation action, the IUCN endorses captive breeding as a proactive conservation measure, one that should be initiated while a species is still available. IUCN, through its Amphibian Specialist Group, sponsors the Amphibian Ark, which tracks ex situ captive breeding activities for amphibians around the world. However, captive breeding is costly and involves many problems to hurdle.
But the most practical approach maybe one launched by local environmentalists of Benguet State University  (BSU)in the Philippines. Professors, teachers, students and farmers are constructing frog ponds for them to multiply and educating students on the importance of frogs.
Led by Dr. Grace T. Bengwayan, BSU’s Save the Frogs Project  has taken an interdisciplinary and integrative approach to rescue the prized amphibians. “This project has implications for how you do science”, Grace said.
“In a sense,  it is about defining the whole conceptual focus of ecology, particularly in that to understand the problem, we have to do a better job in integrating humans into ecological and evolutionary theory,” Dr. Grace said.

Learn to Respect Creation and Treat Them as Sacred by Michael A. Bengwayan



Learn to Respect Creation and Treat Them as Sacred
by Michael A. Bengwayan

The world of the 19th and 20th centuries can be considered as the time that Earth was pillaged at its worst. During those centuries, it was not a sacral world. It was a world losing its quality of enchantment because of mechanistic science and spiritless spiritualities.

The captains of the extractive industries rampaged around and inside Earth--taking by force anything that could run their industries and put money in their pockets. Tribes, communities, countries, habitats,forests, lands, lakes fell by the ways of the masters of disasters.

The powers that be and their partners in research laboratories pushed to transpose the workings of nature into precise mathematical language as if they were dealing with a complicated machine. This Cartesian-Newtonian method, domineering and disenchanting brought forth industrial development, wealth and high standards of living.
But it also resulted to grave ecological consequences.
The consequences we all now feel is increasingly hard to sustain. Worse, it is creating a graveyard for the future generations.

As our economic and environmental limitations become more obvious every day, we are obliged to shift to a new framework of thought. We must revise our assumptions about nature and the role of humankind.

We must see ourselves as part of a larger, integrated totality. A part dependent on a whole, just as a whole depends on the perfect functioning of every integral part.

So where do we fit in this whole system?

We fit in it as part of an interdependent component, which someone has planned since the beginning through a deliberate design. A design made by some infinite creative capacity and inexhaustible imagination.

There is no scientific method that can prove God's existence. And there is also no method that can deny God's existence and His presence in this design.

Because there is nothing to prove.

Even one of the great early scientific minds who denied the presence of a Maker accepted before his death-- astronomer and philosopher Sir James Jeans-- "the universe is not a machine. It is the result of a great THOUGHT by someone.
And as part of that great thought, we were created with non-humans in an environment where we are partly matter. And partly spirit.

As part matter, we are able to reach out to other humans. Either with love. Most often, hate.

As part matter, we reached out to other creation as humans. Mostly using, exploiting and destroying.

As part spirit, we are able to reach out to our Designer and Maker who is pure in spirit. Pure in being.

Next year, and as part spirit, we must now start reaching out to other creation with sacred respect and reverence.

Something we have not done so for the past 2,000 years or so when we were told to be "good stewards".

That is, if we want to preserve our vey own home. Becuase there is no other Earth. And time is running out.

For the Designer will not take it lightly to see His other creations destroyed by those He has entrusted these to be protected.

Water Wars Loom in Water-Rich Philippines By MICHAEL A. BENGWAYAN




Water Wars Loom in Water-Rich Philippines
By MICHAEL A. BENGWAYAN

Baguio City, Philippines –  (December 8, 2017) An eerie calm exists over the villages of Fedelisan, Sagada, Dalican of Bontoc, and Saclit of Sadanga of Mountain Province, Philippines. It is because, there is no telling how many killings will again turn the pristine waters red.  Not too long ago, ten people died and scores injured in prolonged tribal war over water.

Water has become a major bone of contention not only in villages  but also nationwide. Water-related conflicts have been increasing lately. The Philippine National Police (PNP) in the  four regions covering 56 provinces, identified 34 areas last year where shooting and killing erupted due to conflicts on water rights, boundaries, use and sharing.

In urban areas, it may not be long before the problem of diminishing water resource goes uncontrolled towards social unrest.  Per capita demands are increasing and per capita water availability is declining due to population growth and trends in economic development.
The country’s capital Manila is the most vulnerable to water scarcity, so  are the major cities Baguio, Cebu,  Bacolod, Iloilo, Olongapo,  Angeles. Cagayan de Oro, Pagadian and Davao city;  the Philippine Center for Water and Sanitation (PCWS) said. These cities are currently experiencing severe water shortages.

Enough Water But Unavailable For All
It may be unthinkable because according to Dr. Peter H. Glieck of the Pacific Institute for Environment (PIE), the country happens to have 323 km^3 per year of total renewable fresh water supply, third most bountiful in Southeast Asia after Indonesia and Malaysia. But think again. Of that amount, the country can only withdraw a total of 29.5 per cent yearly of water.

Dr. Glieck reported in the 2012 edition of the “World Water” says, the Philippines will need some 393 per cent of total withdrawal starting year 2000 until the next ten years. Of the total withdrawable amount, 18 per cent is consumed for domestic use, 21 per cent for industrial purposes and 61 per cent for agricultural irrigation.

Luzon itself is a paradoxical case. Even with the Gran Cordillera, Caraballo and Sierra Madre ranges which cradle three giant river basins; Agno, Angat and Cagayan, water scarcity has not only become a problem in the country’s biggest island. It is also causing sanitation constraints and increasing incidences of water-related diseases and amount of land irrigated is falling as competition for agricultural water is being strained to the limit.

Deforestation and Water Mismanagement Are Culprits
Not surprisingly, massive deforestation  is behind the problem. Deforestation is rampant nationwide. If the country’s deforestation rate pegged at 1,500 hectares a day as of 1995 by the World Resources Institute (WRI) is not scary enough, deforestation rates in several provinces  are more alarming with many provinces falling below the  ideal 60:40 forest-settlement ratio to maintain ecological balance.  The Cordillera Ecological Center, an environmental NGO at least six provinces in the Cordillera region have only between 20 – 30 forest cover, based from LANDSAT estimates, with the province Benguet having the least forest cover.

The country itself has only a little more than 4 million hectares of forests left, 700,000 hectares of which are virgin forests as bared by former Senate committee on environment Sen. Loren Legarda. But it may not be long before these are wiped out, what with the deforestation rate far outstripping reforestation efforts.

According to former director of PCWS Director Rory Villaluna, deforestation is not the only cause for worsening water inadequacy. Rather, water resources like river basins, rivers, creeks, brooks and underground water are inadequately protected, conserved and rehabilitated. She said water levels have not only gone down. These are being polluted at an alarming rate such that it is not fit for domestic or agricultural use.

Such statements only prove Sen. Legarda’s lamentable revelation that only one forester guards and protects every 3,000 hectares of forests in the country.

“We often equate water with forests but actually ill water management and use has only aggravated the sad state of our watersheds—our main sources of water. Much water, if not only polluted and poisoned can be used back for the burgeoning population”, Villaluna says. “We ask what forests can give us, but we don’t do enough to give back to conserve our forests and water”, she added with finality, albeit hinting that water should really be managed..

Dying Rivers
The Agno River of the Philippines is a very good example. While it feeds three dams—San Roque, Ambuklao  and Binga which generate 1,200  megawatts of electricity,  is dying.

From its headwaters in Mount Data and Loo, Buguias, Benguet, now the country’s center of highland vegetable production, toxic pesticides find their way to the river. All along its stretch, vegetable gardens using dangerous broad spectrum pesticides exist. The deadly chemicals eventually find their way to the river through soil and water surface as well as underground run-off.

As the river reaches Itogon municipality, cyanide and mercury from the various mines and hundreds of pocket miners seep to the river. A Japan Integrated Cooperative Agency (JICA) study in 1990 showed that at Lingayen Gulf, Pangasinan, the delta of Agno, shellfishes have trace deposits of cyanide and mercury.

Mercurial and cyanide poisoning cause weakening of the human body,  and these are characterized by symptoms coughing, vomiting, reddening of eyes, nausea and difficulty of breathing, Dr. Charles Cheng, a noted medical researcher and director of the Baguio-based Chinese-Filipino General Hospital said.

Because both have cumulative effects, they may not kill instantly in small deposits in the human body. But when accumulation defeats the tolerable level of the human body, instant death occurs, Dr. Cheng said.

Aside from the two deadly chemicals, an independent assessment team commissioned by the Friends of the Earth (FOE) and the International Rivers Network (IRN) found several more harmful chemicals in Agno’s river. Dr. Sergio Feld of the team identified these as lead, selenium, molybdenum, iron, manganese, zinc, arsenic, copper, nickel and even radioactive compounds like uranium.

The Manila-based Upland NGO Committee (UNAC) say 27 rivers which used to provide household water, irrigation, fishing haven, and washing and swimming grounds are “crying in silence” as they go to die in dams or either run dry. UNAC Committee member and secretary general of the NGO Bantay Mina Nestor Caoli says six of the 27 rivers – Balili, Agno, Baroro, Balincaquin, Bued and Dagupan—are biologically dead due to mining.

Six more rivers are heavily polluted and silted by mining activities. These are Naguillan, Upper Magat, Caraballo, Santa Fe, Amburayan and Pasil. Expanding agricultural operations are pouring pesticide elements into the river, Caoli said. The dead and dying rivers are adversely affecting economic and social activities of people living within and along the rivers’ headwaters and tributaries, UNAC said.

CEC added one river that feeds the country’s vegetable bowl, Balili River is being killed mainly by solid waste pollution including human excrement from Baguio City, a known highland tourism city. An estimated 3,000 tons monthly of human excreta is treated by the Baguio Sewage Plant but still find their way to Balili river.

The Cordillera, it appears, is fast turning out to be the region of not only the “dammed, damned, but also of dying rivers”,CEC said.

The government’s Environmental Management Bureau (EMB) of the DENR came out with a different view but still complements the above-said findings of the NGOs. It says Amburayan and Baroro rivers of La Union are dead, so are Agno and Dagupan of Pangasinan.

Even rivers in Bulacan and Batangas are dying; Balagtas, Bocaue, Guiguinto, Marilao and Meycauayan in Bulacan and Dumaca-a in  the  province of Batangas.

In Luzon’s heart, Metro Manila, nine river sub-basins are may soon have only poisoned water. These are Obando-Malabon-Navotas estuary in Balut and Malabon, Marikina in Payatas, Tullahan in Valenzuela, the three Taguig-Napindan river basins in Taguig and Taguig-Napindan in Fort Bonifacio. These are in the most critical situations among the country’s 18 river basins whose areas total to more than 110,000 square kilometers.

No Water Means Death Of Communities
The dead and silent rivers are now the subject of fierce rhetoric from environmentalists hell-bent on protecting what is left of the country’s water sources. NGOs in Luzon look squarely at logging companies, mines, dams and insensitive farmers as culprits. Forester George Facsoy of the Cordillera Ecological Center,  for instance, sees the death of rivers as the decapitation of communities from the ecosystem that once supported them.

In the Cordillera, “water is looked upon as life itself”, as the Igorot hero Macli-ing Dulag once said. Death of a river means people will suffer deep economic recession. There will be no farms and fishing areas, and people will be marginalized, making them dependent on outside culture difficult for them to adapt to, he said.

The precious water from rivers replenishes the paddies and deposits fertile silt onto thousands of hectares of farms which foster populations along rivers. If and when the rivers run dry, the imprint of many centuries of human civilizations’ cumulative toiling, ethnic culture and identity will be forever lost, he said.

Groundwater Will Be Affected
The extinction of rivers will directly affect underground water resources, the National Water Resources Center (NWRC) warned. Of all the nation’s provinces, only 12 have groundwater resources that are expected to provide water in the near future. Not one of these has a groundwater area of more than 30,000 hectares—meaning—population density will definitely bear hard on water that these sources can provide.

Groundwater, often looked upon as an unreliable resource, is possible of being lost . It is very vulnerable and with the water and sanitation sectors’ poor management of it, like surface water, it may soon be lost to oblivion

If so, biodiversity will be lost too, and economic and social activities will altogether be disrupted, especially in the lower regions.

Waters wars Will be Fought This Millenium
The specter of water crisis will cause communities to fight tooth and nail for possession and use. The politics of water is as difficult as preventing a war. It makes rivers no longer “deep and wide” as the song goes, but the rift between communities.

Sandra Postel of the influential Worldwatch Institute says “in efforts to seek and prevent water as flashpoints of conflict, there is a must for mediators to allocate strategies where communities or nations can agree to equal sharing.” Easier said than done, especially so when no law exists where pressure is put on lower communities to either pay for the water that flows or die without. Moreso, putting water scarcity to the already crowded policy agenda of the government has not yet been done with genuine interest by Philippine law-makers. Even though the challenge to recognize water scarcity as an increasingly powerful cause of political and social instability is so great. In fact, politicians have yet to pass a Code of Conduct for the water and sanitation sector.

“Communities and even counties will go to war”, warned  Facsoy and the government may find it too late to act.” The villages in Mountain Province are not the only volatile places. This year’s drought, the impending long, hot summer and El Nino next year, need not spell these out./MICHAEL A. BENGWAYAN
