WATER POLLUTION: CAUSE, EFFECT, SOLUTIONS
Careless human pollutions affect many areas in the world. The wastes that humans disposed and dumped everywhere come back to them in very undesirable manner.
The oil spill of the Exxon Valdez showed the world how horrible the effects of water pollution could be. Even though the spill barely affects the surface of the problem of water pollution, the spill became the turning point for the government to act upon the reactions of the people, an article discussed.
Oil is just one of many pollutants that people dump into the water. Every year, 14 billions of sewage, sludge and garbage are also dumped into the world’s oceans. Annually, 19 trillion of wastes enter water.
Water pollution affects every nation around the globe. The problem had been intensified as the world continued to industrialized and the population increases.
It is not actually illegal to dump pollutants into bodies of water though restricted. It is the major reason why industries, buildings and factories dumped their wastes into oceans and seas. This results to severe and alarming water pollution.
Across the globe, about half of all sewage is dumped into the sea and other bodies of water in its original form. But no one cared to disinfect and remove the harmful pollutants. Even the wastes are treated, sewage form sludge and often sent out to the sea. People should know that the effects are really dangerous. The effects of the chemicals dumped into the water may also vary and depend on the chemicals.
The toxic waste and sewage kill lives that inhabits on water- based ecosystems. This results to often winding up of dead fish, birds, dolphins, etc. on the beaches.
Pollutants like lead and cadmium are eaten by small animals, and then consumed by the fishes and shellfish. The food chain continued to be disrupted at all levels. Eventually, humans are affected. The people get diseases like hepatitis because of eating poisoned seafood.
These events come to the point of restricting the industries from dumping materials into bodies of water. Non- governmental projects and organizations as well as environmental groups help each other in their clean up efforts to maintain the healthy bodies of water.
Industries also cooperate through reducing the amount of chemicals they dumped into seas and oceans. The plastic industry also helped through making their product degradable.
The public has been very influential to the government in implementing environmental laws. Their reactions upon the harmful effects of water pollution became the turning point for the governments to intervene. Somehow, it should not be just the government who should take actions. The public as well should do their part as citizens of the country and as stewards of God.

EARTHLY TRUE
“The phrase "conquest of nature" is certainly one of the most
objectionable and misleading expressions of Western languages.
It reflects the illusion that all natural forces can be entirely
controlled, and it expresses the criminal conceit that nature
is to be considered primarily as a source of raw materials
and energy for human purposes." From A God within by René Dubos

The Earth
- The Earth has been around for 4.6 billion years. Scaling this time down to 46 years we have been around for 4 hours and our Industrial Revolution began just 1 minute ago. During this short time period we have ransacked the planet for ways to get fuels and raw materials, have been the cause of extinction of an unthinkable amount of plants and animals, and have multiplied our population to that of a plague.
- Despite all of the damage we have caused the environment most of it is reversible. We can restore habitats and return species to them; clean rivers; renovate buildings; replenish the topsoil, replant forests. However, these activities do not relieve the worst symptoms of the damage. We still have to fix the source of these problems, us and our vision that we must progress.

REDUCE, REUSE, AND RECYCLE: SUGGESTIONS FOR CHILDREN
REDUCE
* When you go shopping, take along a bag and tell the cashier that you won't need a new one.
* Avoid buying fast food unless it is served in recyclable packages.
* Boycott products that are over packaged. Choose items packaged in containers that are recyclable or made of recycled materials. Write to companies and tell them why you are making these choices.
* Don't buy or use disposable products. Switch to cloth napkins, carry drinks in refillable thermos bottles, and carry your lunch in washable, reusable containers. Instead of paper towels, use a cloth or sponge to clean up.
* Don't buy aerosol cans. They can't be recycled, and they contain ingredients which cause air pollution. Instead look for spray bottles or other alternatives.
* Try to avoid creating hazardous wastes. Many household cleaning products can be replaced with simpler, less hazardous materials.
* Reduce your use of batteries. They contain heavy metals that are toxic. Try to use mechanical objects, ones that plug in, or rechargeable batteries.
REUSE
* Donate outgrown toys and clothing to a worthy cause, rather than throwing them away. Even worn-out clothing can be used as rags for cleaning, car polishing, etc., rather than using disposable paper towels.
* Create a compost pile. With very little effort, yard wastes and food scraps can be made into compost, which will help your garden or yard to grow.
* Learn to fix things rather than throwing them away. When buying new objects, look for sturdy ones that will last for a long time.
* If you or your family has old magazines or books you want to get rid of, donate them to a hospital, nursing home, or waiting room rather than throwing them away. Share a subscription with a friend.
RECYCLE
* Find out what is recyclable in your community, and help your family to make whatever changes are necessary to recycle everything possible.
* Ask your parents to buy drinks in glass or aluminum containers instead of plastic, since glass and aluminum are easier to recycle. Avoid buying drinks in unrecyclable containers.
* Whenever possible, choose products made from recycled materials. Unless people want to buy recycled products, companies will not produce them.

PRECYCLING
image from http://thedesigninspiration.com/fonts/eco-environment/
It is easy to blame others for abusing the environment, but in just one year the New Yorkers created more than 21 million tons of solid waste. Americans are more wasteful than people in any other country. Recycling is one solution, but not the only one. PRECYCLING and WASTE REDUCTION mean making less garbage. Precycling is the easiest and cheapest way to deal with the garbage glut and help our environment. See how many of the following ideas you can try:
1. Choose reusable alternatives to disposable products:
a. A sponge instead of a paper towel
b. A reusable razor blade instead of disposable shavers
c. A mug instead of disposable (plastic or paper) cups
d. Washable plates or china instead of paper plates
e. Cloth napkins instead of paper ones
f. Cloth diapers or diaper service instead of disposable diapers
2. Be an environmental shopper:
a. Don't buy things that are over packaged. Ask yourself, "Is this packaging really necessary?"
b. Avoid single serving packages
c. Use a soap bar instead of liquid soap dispensers
d. Buy toothpaste in large tubes instead of other, more wasteful containers.
3. Buy in bulk to reduce packaging waste that is thrown away:
a. Buy concentrates of products like detergents, cleaners, and juices
b. Buy large sizes of products c. Buy fruits and snacks loose instead of in packages
4. Bring your own bags to the grocery store. When you're asked "paper or plastic," say "No thanks, I have my own bag." If you buy only one or two items, don't use a bag.
5. Use both sides of a sheet of paper when making copies or writing. Reuse glass, plastic and metal containers to hold small items such as bulk purchases, sewing supplies, crayons, hardware, etc. Cardboard boxes can also be used again.
6. Invest in a battery charger and use rechargeable batteries, or better yet, avoid using batteries whenever possible.
7. Share your magazines and newspapers with your friends. Bring recent magazines to hospitals, nursing homes, doctors and dentist offices.
8. Cut down on junk mail by writing to:
Direct Marketing Association 6 East 43rd Street New York, NY 10017-4601
Ask them to take your name off unwanted mailing lists.
9. Donate reusable clothes, toys and other items to charity. Make old clothing into new by painting or decorating or remodeling in some way. Make rags out of unusable clothes.
10. Get your nickel back. Return used soda and beer containers to the store to redeem your deposits. Yes, the big plastic bottles too.
11. Repair appliances and furniture instead of throwing them out. It's usually less expensive.
12. Write to manufacturers about excessive packaging. They'll listen.
13. Compost grass, leaves and other yard waste in your backyard.
14. Tell your friends, family and neighbors that precycling is here.

I WRITE. . .I DO. . .
We could be able to work on saving our destroyed environment. We should start it to ourselves. Writing articles will not be able to help if actions aren't taken.The stories we wrote are only guides for the readers to do such things that would generate good effect to the society.
We all know how bad the present condition of our environment is. But, instead of helping in making it sound and healthy, many people just loved to make it worse than ever.
Our national hero, Dr. Jose P. Rizal thought that the youths are the hope of our Father Land. But it seemed that the youths are the ghosts of our society.
Our parents sent us to school to learn, to acquire knowledge which we can use for the betterment of our self as well as the others. Everything we've learned must be put into actions ---- desirable and helpful actions that would make yourself proud of you.
We all learn in school ---- through the books, lectures and experience. All those learning must be done well and properly for a good outcome. High grades in our class cards era not enough to say that we excel.
2015 is approaching but it seemed that the Millennium Development Goals are still flying in the air. Or we are not just aware of the developments? But why?
It is one of the MDG's that the environmental sustainability of every nation in the globe must be ensured. But, in every day that I woke up, it seemed that no one cares about it.
More issues about the environment come out, more articles are published, more problems are viewed in the television, still no one seemed to care. Even though many laws are passed in the congress, if the people do not follow them, nothing will happen.
Do not say that you can nothing. Everyone has the potential to help in achieving at least the MDG No. 7 ---- Ensure Environmental Sustainability. By simply planting trees, cleaning your grounds, dumping the right kind of waste in a right place and following orders of the government, you can be a great help to Mother Earth.
Being aware may help. Be one of the people who encourage everyone to restore our environment. Be the voice of our Mother Earth.

SAVE ENVIRONMENT-SAVE EARTH
Environment is our surrounding which includes everything from a non-living to a living being. There are two kinds namely the natural environment and Built environment.
The natural atmosphere is being polluted due to the unnatural factors. While natural causes like volcano's have its own turn in causing pollution it is the man made ones that are more rampant. It is the reckless and the caustic human nature that is primarily responsible for the environmental pollution. It is the self centered humans that are causing more destruction to the environment.
It is natural for every human being to live in the circumstances they are born and any changes to it causes a lot of trouble. Built environment, which lacks natural components, has become quite significant in today's era. There is a lot of environmental peril that has been responsible for the problems associated with mother earth like Global warming Land degradation pollution etc.
Global Warming is defined as the increase in the average temperature of the earth near surface air and ocean since the mid 20th century and its projected continuation. There is a lot of heat caused to the earth due to the green house gases that get rapt in the suns rays thereby causing global warming.
It is the growth in population and also the economic advancement that has added to pollution as well. Every living and non living thing is being affected by this so one must understand that biophysical environment is meant for all and understand the importance of ecological balance.
The consumption of petroleum has to be brought down by one and all. The first step towards reducing our dependence on petroleum is to understand what products are made from petroleum. It is necessary that one takes sufficient measures to reduce the environmental degradation. It is better that we look for natural solutions like shift to a more fuel efficient vehicle make use of paper bags try to economize by using the car pool or public transport, go by walk or use a bicycle, recycle things etc.
It is the responsibility of every person in checking the causes that affect the environmental disaster and play a positive role in improving it and these things have also got to be mentioned. One must realize the importance of a healthy environment and that it is for his/her own benefit to protect it and to take measures to make the world clean and green because as the proverb says "We won't have a society if we destroy the environment".

CONSERVING THE ENVIRONMENT
The condition of the environment is a worldwide issue. Air and water pollution do not recognize borders; poor soil conditions in one nation may reduce another country’s food supply. At the same time, different regions do face different problems. One key distinction is between the environmental threats faced by developed nations, such as the United States and western European countries, and developing nations, such as India and Mexico. Most agree that these nations may have dissimilar crises, but debate remains over whether the solutions to their problems are unique as well.
The environmental problems faced by developed nations are largely the result of their economic strength and higher standards of living. Overconsumption is cited by many observers as a cause of resource depletion in the First World. Americans, and to a lesser extent western Europeans, Japanese, and other residents of developed nations, are more likely to own one or more cars, purchase more food and clothes than subsistence levels require, and use considerable amounts of electricity. Americans consume a disproportionate amount of the planet’s resources. The United States is home to 5 percent of the world’s population but uses 25 percent of its resources. Overall, the developed world has 23 percent of Earth’s population but consumes two-thirds of the resources. Environmentalists contend that this high level of consumption will ultimately lead to the depletion of the planet’s resources, resulting in adverse consequences for human populations.
Developed nations have reduced their rate of population growth, so overpopulation is not as great a problem as it was previously considered to be; however, because of the high level of consumption, each new person in a developed nation will use three times as much water and ten times as much energy as a child born in a developing country. The industries needed to create products for consumption also affect the environment through the emission of greenhouse gases and other wastes.
In contrast, the environmental crises faced by developing nations are the result of poverty. For example, Third World countries often lack the resources and sanitation facilities to provide the public with clean water. Tropical deforestation, caused by the slash-and-burn techniques of poor farmers, is another dilemma. However, as Rice University president Malcolm Gillis has observed, agriculture is not the only manifestation of the effects of poverty on deforestation. In most, but not all, poor nations, the role of poverty in deforestation is magnified by the ever-more-desperate search for fuelwood by impoverished people.” This search for wood is exacerbated by the key environmental problem in developing nations—overpopulation. Third World nations may consume vastly less than America and Europe but their population growth rates are much higher. These nations lack the natural resources and social services that will be needed in order to provide their burgeoning populations with adequate food, shelter, and employment in the coming years. As developing nations move closer to First World status, the accompanying growth in industry could also affect the environment, especially through the emission of greenhouse gases. The global warming agreement reached in Kyoto, Japan, in December 1997 exempted developing nations such as China, India, and Mexico from requirements to reduce their emissions. But according to the United Nations, countries exempted from the agreement will create 76 percent of total greenhouse gas emissions over the next 50 years.
The exemptions in the Kyoto agreement (which must be approved by 55 nations but as of this writing has not been submitted to the U.S. Senate for ratification) raise the question of whether developed and developing nations should utilize the same methods in order to conserve the environment. If the environment truly is a worldwide issue, then the solutions may also be universal. However, international agreement on environmental issues is often difficult to achieve because countries are not at equivalent stages of social and economic development.
Developed nations rely significantly on government regulations to protect and restore the environment; however, many analysts—particularly Americans— believe that the same economic forces that create the wealth of developed countries can solve their environmental troubles. Industry, capitalism, and the freemarket system might create overconsumption, but they can also solve its ill effects, these commentators maintain. John Hood, the president of the John Locke Foundation, a policy institute that advocates the free market and limited government, writes, “Corporate America’s unique contribution to solving real environmental problems will come from innovation—finding new ways to produce goods and services, package and deliver them to consumers, and dispose of or recycle the wastes generated by their own production or by consumption.” In contrast, a system in which the government owns all the land or imposes strict command-and-control regulations on people and businesses is seen as ineffective. The poor environmental condition of communist nations is often cited by these observers as evidence of the inability of government regulations to conserve the environment.
As developing nations grow and become more economically self-sufficient, industrial solutions may become more viable in those countries. However, many commentators assert that Third World and post-communist countries should not follow the United States’ lead. These observers see industry as the planet’s foe rather than its savior; they believe companies are more likely to be motivated by the quest for profit than a desire to preserve the environment. A better way to improve the environment is to rely on a country’s indigenous values, many people maintain. For example, some environmentalists believe that the religious traditions of India promote ecologically friendly values, including vegetarianism and a moderate use of resources. They also prefer traditional agricultural methods, which do not rely on pesticides and chemical fertilizers and therefore do not cause groundwater pollution. Frances Cairncross, a senior editor at the Economist, is among those who argue that if industry is to be relied upon, it should be as environmentally advanced as possible: “Industry in the developing countries has a special opportunity. Because it is making new, ‘greenfield’ investments [investing in undeveloped and often unpolluted land], it can leap a stage and go straight to the best modern practice.”
As noted earlier, the Kyoto global warming agreement reveals the difficulty of finding universal solutions to environmental problems. Developing nations would not consider even voluntary participation in emission reduction, arguing that such measures would impede their efforts to improve their economies and industries. Even within developed nations, the response to the treaty has varied. In June 1998, the European Union reached an agreement that will reduce their greenhouse gas emissions by 8 percent. However, many people in the United States have more negative attitudes toward the agreement; they assert that achieving the reduced emission levels could hurt the nation’s economy. For example, some American analysts contend, companies might move their plants to developing nations, causing job losses in the United States. Moreover, they argue, emission controls could cause U.S. oil and gas prices to rise. Although the Clinton administration played a key role in reaching an agreement in Kyoto, President Bill Clinton is among those who believe developing countries need to limit their own greenhouse gases before the United States can ratify the treaty. Without the participation of the United States—the world’s leading polluter— the treaty might not succeed.
As the Kyoto controversy suggests, international agreement over solutions to global environmental problems is not easily attained. The debate over environmental issues in the United States is also divisive. These global and national debates are the subject of Conserving the Environment: Current Controversies. In this book, the authors examine such topics as the state of the environment, the preservation of biodiversity, methods for reducing pollution, and whether the free-market system can solve environmental problems.

OZONE DEPLETION: CAUSE, EFFECT, SOLUTIONS
If the ozone layer will be destroyed, the ultraviolet rays sent down by the sun will enter the earth and ruin the life of human and the environment the ozone layer protects both plants and animal life from the ultraviolet rays of the sun. And its destruction could give catastrophic effects that would lead to the extinction of the next generations.
Ozone is bluish gas a very dangerous pollutant responsible for producing the greenhouse effect. It is present in the stratosphere that absorbs the suns rays.
In the mid 1980’s, the depletion of the ozone layer was discovered. A massive hole in the ozone layer was seen by experts in 1984 right above Antarctica. It does not only threaten the continent but also others that could be victims of Antarctica’s melting ice caps.
The production and the emission of CFC’s (chlorofluorocarbons) is the leading cause for this environmental problem. CFC’s are used by industries in a variety ways and inventions of many products. That is why industries that use the CFC do not want to discontinue the usage of the highly valuable industrial chemical.
Chlorofluorocarbon was discovered by an American chemist Thomas Midgley in 1930’s. Since then, people did not realize the disaster caused by the use of CFC in the Stratosphere.
Chlorofluorocarbon was discovered by an American chemist Thomas Midgley in 1930’s. Since then, people did not realize the disaster caused by the use of CFC in the Stratosphere.
CFC’s are used in refrigerators, home inculcation, and plastic foam and throw away food containers. As CFC entered the stratosphere, the chlorine atom is removed from them then attacks one of the three oxygen atoms of the ozone molecule. A single chlorine atom destroys over 100, 000 molecules of ozone.
In every 1%of the ozone layer that is depleted, 2% more of UV-B is able to reach the surface of the planet. UV-B can cause skin cancer.
Research shows that as ozone layer decreases, malaria and other infectious diseases increases in rate.
In the environment, the life cycle of the plats will change, the food chain will be disrupted and the effects on the animals will be severe.
Oceans forest and deserts will also be harmed. The most basic micro organisms such as plankton may not able to survive that would result of death of all other animals that depends on the existence of the other animals above plankton in the food chain.
Wind patterns would also change that would result to climatic changes throughout the world. Thus, the problem with the production and emission of the CFC would be difficult if not impossible. It is hard to solve because a great quantity of CFC is in the environment already. And even if is again produced, CFC would remain in the stratosphere for another 100 years.
Despite the difficulties, international actions are taken into the limit CFC production, reduce usage of CFC usage and star encouraging other Countries to sign treaties and write laws in restricting the use of CFC.
People’s awareness towards the danger of ozone depletion could be a great advantage in achieving the goal of the world’s action in combating the disaster.

Note:
Ultraviolet B: One of the three types of invisible light rays (together with ultraviolet A and ultraviolet C) given off by the sun.
Although ultraviolet C is the most dangerous type of ultraviolet light in terms of its potential to harm life on earth, it cannot penetrate earth's protective ozone layer. Therefore, it poses no threat to human, animal or plant life on earth.
Ultraviolet A and ultraviolet B, on the other hand, do penetrate the ozone layer in attenuated form and reach the surface of the planet. Because ultraviolet A is weaker than ultraviolet B, scientists long blamed ultraviolet B as the sole culprit in causing skin cancer in persons with a history of sunburn and repeated overexposure to ultraviolet radiation. Recent research, however, has also implicated ultraviolet A as a possible cause of skin cancer. In addition to natural light from the sun, artificial light from tanning lamps contains ultraviolet A and ultraviolet B. Electric arc lamps can also generate ultraviolet light to heat furnaces for melting and to enable motion-picture projectors to show movies.
Though ultraviolet light can damage health, it can also maintain or improve health. When ultraviolet light strikes human skin, it triggers the production of vitamin D, which promotes the growth of bones and teeth.
SMOG: CAUSE EFFECT SOLUTIONS
Smog is a combination of the worlds smoke and fog which was invented by a Glasgow public health official, Des Voeux.
Smog causes a smoky dark atmosphere that decreases the visibility and creates the haze throughout the area. In many areas of the worlds dirtiest cities, millions of inhabitants are threatened by smog.
Smog is caused by different factors and enters the atmosphere with over 100 chemicals. It includes carbon monoxide, dirt, soot, dust, and ozone. As the sunlight, hydrocarbons and nitrogen oxides mix together, the smog’s effect was created.
Automobiles, fires, waste treatment, oil production, industrial solvents, paints and coatings are major producers of smog. There are huge contributors of particles and chemicals tat produces smog.
The areas that are highly covered with smog severely affect the people. It immediately creates harmful health effects like lung cancer. In cause minor pains like chest pains, cough and throat irritation, because smog irritates and inflames the pulmonary membranes. Even minor exposure of the asthma patients to smog may cause asthma attacks.
Agriculture is also harmed by smog where soybeans, wheat, tomatoes, peanuts, lettuce and cotton are infected when exposed.
As smog levels increase, wind could carry it to far areas and harm the people and the ecosystem. But, it could be decreased by limiting the processes that create it.
Laws could encourage procedure of automobiles to develop cars that produce less smog, watch over chemical companies and restrict them from producing harmful substances and products such as barbecues house paint and kitchen cleaners.
In United States, the government of Denver Colorado, requested people not use their cars at least once a week, encourage the use of oxygenated fuels and experimented fuels with less smog production.
Also in Los Angeles the City Council required carpooling offered free bus services and created many environmental friendly regulations for homes.
Scientists and corporations are testing new fuels from new sources and try to replace other products that creates problems.
In the future, cities and countries have to acquire the ways in combating smog, hopefully before it create the worst problem that it can bring in the areas.

HAZARDOUS WASTE: CAUSE, EFFECTS AND SOLUTIONS
Waste creation is something people do not often think about. Human produce them and dumped them on the environment. Sometimes, these wastes are hazardous and dangerous.
The levels of the hazardous wastes all over the world continue to grow. It is for a reason that humans continue to multiply. Even if the problem is actually seen by the naked eyes, many people and industries who are the main contributors of the wastes seemed to unnoticed its effects. Except if someone had already die or became complicated because of it.
Humans failed to prevent the creation of hazardous waste or limit its negative effects. It is often assumed that wastes end by simply removing them and dumping or sending them to landfills. These wastes that are risky to both humans and animals could always find their way into the ground and eventually into our bodies.
Based on an article, over 80,000 different chemicals are used in industries worldwide. It is difficult and expensive to get rid of these chemicals that cause hazardous wastes because more areas around the world began t industrialize.
Health problems starts to increase yet people seemed to be unwilling to prevent and decrease the amount of hazardous wastes. Usually, the children are the most prone individuals to the effects of these problems. Just like in 1989, a school on New Jersey had to close. Students suffered from excessive exposure to chromium.
Some successful solutions to the problems had been suggested and used. Like the problem in air pollution, wastes can also be controlled through input and output control.
Policies and regulations made by the governments are initiated. Like the increase regulation on the disposal of hazardous waste and limiting industries in producing big amounts of waste or provide them incentives to create less waste.
Humans as the major contributor of waste should put in mind the effects of the hazardous throw away. Individuals could help by choosing not to buy products which requires the production of hazardous waste, influence the policy makers and produce less hazardous waste themselves.
In achieving a goal, everyone must get involved. Like this one, the production of hazardous waste can be at least decreased if not eliminated if the people will be educated and informed about it.
