"Ours, a water planet. The ocean covers 71 percent of the surface of the globe, and it constitutes over 90 percent of all habitable space on Earth. It's total volume is around 300 million cubic miles and its weight is approximately 1.3 million million million tons. No wonder that Arthur C. Clarke, scientist and writer, once remarked that it was 'inappropriate to call this planet Earth, when clearly it is ocean.* * (Mulvaney 28). Ocean pollution is growing out of control, and the clean up of our world's oceans is critical.
Ocean pollution is now a big problem facing us in everyday life. For years we have been trying to stop the dumping of trash, chemicals, and toxic waste into our oceans but the people who do it,...show more content...
It Is also said, that at any given time, the ocean contains over 280,000 tons of tar balls. All kinds of garbage, ranging from fishing nets to trash, from cargo ships to litter on the beaches, finds its way into coastal waters and the ocean. Here, it traps, ensnares, and entangles marine wildlife such as many different species of marine mammals, sea turtles, and seabirds. Plastic pellets have been found on the surface of the Pacific at concentrations of 21,000 per square mile; a cleanup exercise on the coast of Texas yielded 15,600 six–pack rings along 1.8 miles of coastline; and a National Academy of Sciences review once estimated that over 14 billion pounds of garbage enters the ocean from sea–based sources alone. In the 1980's, it was reckoned that 30,000 northern fur seals died each year after becoming entangled in marine debris, principally lost or abandoned fishing gear. Heavy metals––mercury and lead, for example––and organochlorine compounds such as PCBs and DDT, have been associated with a wide variety of impacts on marine wildlife(Mulvaney 29–30). A serious form of ocean pollution might be heading to the coast of New Jersey starting in October. The conflict is that the New York Port Authority wants to dredge New York Harbor, which is full of contaminates such as mercury and other toxic and harmful substances, off of Sandy Hook,
Pollution is Destroying Our Planet Essay
The Earth is a beautiful place to live in, it's amazing how many things we take for granted.
When you can't be bothered leaving your bed, you don't think about the experiences you can have in this world. You don't take notice of the true beauty it brings, instead you overlook it and all you see is cold mornings and school. But what if one day you wake up and it's all gone? Then you would have wished you appreciated it more. You never realise how much you take for granted until you've lost it. Pollution is destroying our planet, through our air, water and land. When will you realise how much your planet does for you?
Above all, air pollution is threatening all life on earth. Most of air pollution we cause results from the burning of...show more content...
Waterways are in serious danger of environmental catastrophe as a result of industrial waste and domestic rubbish. Everything living thing depends on water for life.
Pollution affects marine life and freshwater animals. Factories built on the banks of estuaries have been found dumping residue and waste in waterways. Poisons and other toxins have leaked into the banks destroying species of native and endangered flora and causing outbreaks of disease within these plants. Similar to this has been the impact on the habitats of waterborne creatures interrupting delicate ecosystems and leading to the starvation and death of fish species. The flow on the effect of diseased estuaries can be found in oceans where the food sources of large fish species are being depleted. The impact of waste is compounded by the dumping of domestic rubbish. Plastic bags, aluminium, tin and other rubbish that is an eyesore, becomes an ideal breeding ground for dangerous bacteria that can cause disease. Did you know there is such thing as a pacific garbage patch?
In late 1997 there was a discovery of a new continent that exists between the Hawaiian
Islands and the coast of California. This continent which is approximately two times the size of Texas is not one that is comprised by land. Disturbingly it is a result of an estimated 3.5 million tons of floating plastic garbage that continuously circles in

Pollution
Pollution is the introduction of harmful substances or products into the environment. It is a major problem in America and as well as the world. Pollution not only damages the environment, but damages us also. It has cause many problems ranging from lung cancer to the greenhouse effect. It is all among us but we continue to live in our own filth. What is the reason behind this flawed logic? In this paper I will examine the problems and solutions for this issue.
Automobiles are undeniable the greatest source of pollution. The noise pollution created by cars is immense. Another polluting effect of cars is the heat it creates. This heat makes it unpleasant to be near the car while its running. And of course the most famous...show more content...
American citizens throw away millions of tons of garbage each year, and this trash has to go somewhere. While there are projects underway to clean and reuse this refuse most of it gets dumped into huge landfills. These landfills are disgusting festering blisters on our country's landscape. But people continue to consume and throw away more and more in the name of convenience. As they see it, when things get old, throw it away and get a new one. They blame the government for the trash problem, but the truth blame should be placed on themselves.
The last great source of pollution lays in the businesses. Although not common, businesses have been known to dump their waste products into streams, lakes, and rivers. This may seem like a relatively small occurrence that really is not your concern, but you're wrong. Each time one of these companies pollutes there are horrible consequences to pay. Mutations, destroyed ecosystems, and human death have all occurred as a direct result of illegal dumping. It contaminates our drinking water and soil. It causes entire communities of humans (not to mention animals) to move on to new places not to return for at least a century. The pollutants dumped by industry are so concentrated that a single barrel can destroy an entire lake's ecosystem. Not only do companies dump chemicals, but also hot water. This hot water kills most life it comes into contact with, but also causes an overgrowth
Pollution Essay
Pollution is a nationwide habit that has caused distress among the environment and its inhabitants. This is a serious complication that we as people need to take a stand to develop solutions to prevent contaminating the our water systems, environments, air, and soil. Everyday we witness pollution or participate in polluting our country with our daily tasks. Pollution causes unexpected and devastating changes in our land, river and sea environments("Reduce Pollution"). Pollution got my attention because of how extremely devastating it is to our world. Its effects include deliberately impressing our country with diseases, birth youth defects, and destroying the ecosystem. What actions can citizens of the United States take to prevent the...show more content...
"The United States Congress passed the Clean Air Act in 1963 in an effort to limit the amount of pollutants released into the atmosphere. Since that time there have been several amendments to the act that have served to strengthen it and make it more detailed"(Audet). "The group's annual "State of the Air" report finds 47 percent of Americans live in counties with frequently unhealthy levels of either ozone or particulate pollution"(Roppolo). The high percentage of affected communities shows that pollution is a genuine and demanding issue that we need to recognize and focus on preventing before it gets worse. If the problem is allowed to get worse it may become irreversible.
After discovering that pollution is dangerous to the human body because of its possible effects internally and externally I now believe it is our responsibility to fix the problem. As individuals we need to adopt new new ways to actively prevent pollution such as altering the way we perform our daily tasks so that we emit less pollution. We can all start helping by doing simple things like not littering and beginning to use natural fertilizers (Radcliff). We should not litter especially near water sources and we should use manure instead of chemical fertilizers (Radcliff). We can improve conditions by disposing of hazardous materials such as paint, motor oil, antifreeze and lawn

Automobiles like these are around the world everyday, and their exhaust destroys our air everyday.
Our environment is a major aspect of our life today. Many of us don't take our
Earth seriously and think that as long as pollution doesn't hurt them they can go ahead and throw garbage on the ground or spill oil down the drain. Well to many people have that theory and they are killing off our Earth and also physically harming themselves from the air they breath and the water they swim in. Our Earth is fragile like a human and people don't know. There are many different types of environmental pollution (e.g. Water, air, atmospheric.)

If this depletion opens up dangerous and deadly UV Rays from the sun will come into Earth. Air pollution causes global warming which scientist believe is making the Earth warmer and melting ice up in the South and North
Pole. The country Holland has had water from the ocean got too high for them and flooded into towns. Holland spent millions of dollars to put up "dikes" which are big barriers in the water to prevent their town to be completely submerged.
With the ocean getting deeper coastal cites all around the world could flood, billions of dollars would be spent to try to prevent it, but in a while it could not be stopped. Instead of waiting and having to spend all this money why don't we put it together today and try different ways of preventing air pollution, it would be much easier than all the trouble of stopping flooding.
Water pollution is another major aspect of environmental pollution.
Water pollution is scary because over 75% of our Earth is covered by the ocean.
Water pollution comes from many different sources around the world. One major pollutant that destroys the ocean is oil spills. The oil from an oil spill kills hundreds of sea animals from fish, to whales, to birds. Below is a small list of just some of the major oil spills. Notice how many tons were spilled into our ocean...

Pollution in the World A vast area under discussion, mostly in this day and age, pollution is a poisonous or harmful contamination of the biosphere.
There are many different forms of pollution including litter, industrial effluent, domestic waste, nuclear waste, toxic waste, water pollution, agricultural pollution, noise pollution and air pollution.
Air pollution, being the main area of concern due to its threatening symptoms, comes from a range of various sources such as factories, power plants, dry cleaners, motor vehicles and even windblown dust and wildfires.

Taken from an article by Paul Phillips and Pam Pickering in School Science Review, March 1991.
The main sources of pollution in the lower atmosphere caused by the use of motor vehicles come from three major pollutants generated by vehicles, – hydrocarbons, nitrogen oxides, and carbon monoxide.
Hydrocarbons are an alarm because combined with nitrogen oxides they can produce a brutal chemical concoction. The actual crisis occurs when the sun shines. Chemical reactions can lead to the formation of photochemical smog, a horrible haze that often hangs over urban areas. Nitrogen oxides assist the formation of acid rain. Carbon monoxide, a colourless, odourless and deadly gas can blight mental functions and visual observation and in extreme cases lead to death.
These pollutants are released into the earths atmosphere when –
– Fuel is burned in the internal combustion engine and the gasoline residuals are emitted through the tailpipe.
– Heat causes fuel to

There are many kinds of pollution, but one that has the most impact on humans would be air pollution. In order to live, we must breathe air and surprisingly some things that we breathe takes a toll on our health. Air pollution occurs when pollutants are released into the atmosphere. It has both chronic and acute effects on human health which effects a number of different systems and organsFossil fuel combustion such as diesel fuel, coal, gasoline and natural gas is the main source of air pollution. Most of this air pollution is created by us humans. We realize that the action of one has the potential to affect many others.

There are some long–term and short–term effects that some people do tend to face. Some long–term effects from air pollution include heart disease, lung cancer and emphysema, which is a respiratory disease. These long–term effects can last for some years or maybe even a lifetime. It can get so severe to where it may even lead to a person's death. Also, air pollution may cause some long–term damage to people's nerves, brain, kidneys, liver and other organisms. Nearly 2.5 million people die worldwide each year due to the cause of outdoor and indoor pollution (National Geographic Society, 2012). Interestingly, it can eve cause some birth defects which is a physical disorder present at a child's birth and not developed until later.
Short–term effects of air pollution are only temporary meaning that they come and go. Most will last up to a few days or maybe even a couple of weeks. Illnesses such as bronchitis and pneumonia are examples of some short–term effects. Bad odors from sewer systems, garbage and factories are also considered as air pollutants. This can cause someone to have headaches, nausea and
Abstract On Environmental Pollution
Abstract
Environmental pollution is anything that can cause harm to the environment. Pollution is any undesired alteration of the environment and is often caused by human activities (Mader, 2016, pg. 552). Types of human pollution would be air, water, soil, radioactive, thermal, noise, and light. Each of these forms of pollution has been known to cause the enormous amount of concern for the environment. There are laws in place now that are limiting pollution and to help control the issue. Environmental pollution is a serious problem we are facing globally. It is the debate concerning pollution, which we have been pondering for the past century. Prior to the industrial revolution, scientists thought that the atmosphere was untouched by man–made pollutants until they found air bubbles hidden in the core of Greenland's ice shelf (Stromberg). After finding this essential development, scientist began to reconsider the initial cause of pollution and how to decrease the lasting effects of it. With this discovery, pollution was traced back to Ancient Rome and it was decided that globally we needed a new approach for dealing with this problem. There are numerous types of pollution and they each have a devastating effect on the global climate. A scientist has been working on ways to re–direct the negative effects of pollution and at the same time encourage people to try to find ways to do that part to help with this effort. We all can find some way to improve the world and decrease pollution.
The problems with air pollution seem to be one of the largest most discussed situations. The Natural Resource Defense Council (NRDC) air pollution is the release of pollutants into the air that is damaging human health and world. There are many forms of air pollution and smog and soot are two of them. These two are discussed more when dissecting this problem due to them being the most common forms of air position, which are also the most detrimental of them all. When the sunlight and emissions from fossil fuels interact that is how smog is created. The creation of soot formed from smoke, dust, allergens and other particles are spread throughout the air in gas or solid form. Methane is also a huge component of the
Essay On Air Pollution
Air is an indispensable part of human, animal and plant lives. Without it, no organisms would be able to survive on Earth (Reference, 2017). Due to excessive human activities, air pollution has become a detrimental worldwide issue in current days (Sciencing, 2017). However, scientists have found new chemicals that can assist in improving the air quality (Phys.org, 2017). Moreover, humans are able to adopt many methods to help decrease the severity of contamination released into the earth's atmosphere. This investigation is linked to 'application and limitation' in 'science as a Human Endeavour'.
Chemical Background and Link to SHE
Oxygen is a part of the air and it is responsible for aerobic respiration in humans, animals and some microorganisms to produce energy and to function. Air also contains carbon dioxide, and it is a crucial part of photosynthesis in primary producers, such as plants, for the production of chemical energy (Reference, 2017).
The article 'New Green Solvent Could Help Clean Our Air' has clearly demonstrated the application and limitation of using chemicals to filter the contaminated air that affects human health. In the second paragraph, the author mentioned the shortcomings of existing methods that can clean contaminated air were toxic and expensive. This suggests that scientists understood these limitations and were able to gain new opportunities to develop solutions to polluted air (Phys.org, 2017).
The following paragraph has explained the

Pollution has become a major issue over the years because it contaminates the Earth's environment and affects human health. While some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities. The increase of various types of pollution has made cancer pollutant more prevalent among the people, raising the risk of getting cancer. After being exposed to theses pollutants, the effects may be immediate or delayed. Some of the delayed effects, due to the exposure, can go unnoticed for many years. Another major issue that pollution creates is the tremendous cost for preventing and cleaning it up. However, we can not regulate the pollutants to the extent where there are no more possible...show more content...
One possible way to control the carcinogenic pollutant is to get a bill passed by Congress, which makes it mandatory for industrial places to reduce the amount of pollution they create. By reducing the amount of pollution production, the exposure level of the carcinogenic pollutant will decrease. This law enforces the industrial companies to establish new methods and strategies to create their products with less pollution distribution in the end. As another preventive measure, there are products available to the population that contains carcinogenic elements that can be taken off the market until they are redesigned and approved by the government. One last effort to regulate the cancer pollutant is to increase the funds for research so that we can have a better understanding of cancer and how to cure it. Consequently, we can create better drugs available to the population, which can decrease the chances of people, with cancer, from dying.
Now that we have the regulations into effect, the next thing to do is determine appropriate levels of exposure and the risk level. However, this raises the question of how do determine what a human life is worth. There is no conclusive answer to this question, so we have to take risks. If we take the total number of deaths that occur every year in the world or a particular country and divide that by the number deaths

Pollution occurs when harmful substances or products are introduced into the environment. It is a major problem in America, as well as the rest of the world. Pollution damages the environment and does harm to humans and other animals. It creates many problems, from lung cancer to the greenhouse effect. Oblivious to the damage they cause, rednecks continue to throw trash out of the window instead of walking two feet to a garbage can. The laziness of these types of people creates problems for the entire planet. People must realize that something needs to change. Why does our world continue to become more polluted year after year?

In today's society when something gets the slightest bit old, it must be thrown away and a new one replaces it. The citizens blame the government for their trash problem. The over consumers must take the blame for this situation. The last major source of pollution is in the businesses. In a few rare instances, businesses dumped their waste products into streams, lakes, or rivers. This may seem like a relatively small occurrence that does not affect most people. However, horrible consequences result every time a company pollutes a water system. Mutations and human death have occurred as a direct result of illegal dumping. Illegal dumping contaminates our drinking water and soil. The pollutants dumped by industry are so concentrated that a single barrel can destroy an entire lake's ecosystem.
Despite the severity of the pollution problem, it can be solved. Individuals can do a lot to save the environment. Instead of driving, carpool with a friend or take a bus. This will not only cut down on the pollution due to cars each year, but will also save money on gas. Taking the time to sort your trash and placing it in the appropriate recycling bins can also do a lot for the environment. Recycling reduces the amount of waste piled into landfills. Also, pay attention to the products you buy and how they are packaged. Do not buy items that will be thrown away due to lack of use.

Environmental pollution is the key concern for the humanity. It does not have any borders each member of our planet is affected by its devastating effects. Air pollution is the main factor contributing to general environmental problems. It is the emission of particulates, harmful materials, and biological molecules in the Earth's atmosphere and is caused by both human and natural factors. The effects of air pollution are shocking. It causes numerous diseases in human organisms, animals, natural crops, ruins the balance of the environmental system, and even causes deaths. Air pollution is the largest environmental pollution risk factor. According to the research of World Health Organization,...show more content...
The negative effect on human health also affects the central nervous system. The studies confirmed that an early exposure of children to the higher levels of air pollution have the same negative effects on the central nervous system as autism spectrum disorder and schizophrenia. Low and middle income countries in the South East Asia and Western Pacific Regions have the highest mortality rate due to air contamination problems. Specifically in this region, World Health Organization attributes approximately 3.3 million deaths to indoor and 2.6 million deaths to outdoor air pollution annually. "The most polluted country is India. It has the highest mortality rate due to air pollution. Most deaths in India are caused by asthma. Another seriously affected country is China." The report of World Health Organization states that air pollution killed more than 500,000 people in China in 2014. The calculations performed by the European Commission show that polluted air reduces the life expectancy in EU by more than nine months. The worst situation is in Benelux and Italy.
The research of the Johns Hopkins Bloomberg School of Public Health revealed that even a small exposure to the polluted air during pregnancy results in pregnancy complications. And long term health problems of the future children. The fetus is extremely sensitive to environmental factors. "The study concluded that the greater the exposure of the pregnant woman to the air pollution is, the higher

Introduction
From my studying in this unit, I understand that air pollution transpires in various patterns, however, it can generally be thought of as gaseous and particulate contaminants that are existing in the earth's atmosphere.
Chemicals discharged into the air that has a direct impact on the environment are called primary pollutants. These primary pollutants sometimes react with other chemicals in the air to produce secondary pollutants.
Air pollution has become a very high–priced environmental predicament when one views it in line with human lives and looking at it from the perspective of repairing damages in humans the money spent on health care and also crop damage.

Cause And Effect Essay On Air Pollution
Pollution has become a prevalent issue worldwide and has begun to affect the air used to breathe, the soil used to grow food, and the water used to drink. All of these effects result in commonly occurring destruction of health and wildlife that one may have seen on the news or heard from peers. In order to live, one needs food, water, clothing, and shelter. If the water and food that society consumes gets contaminated, a major component of life has been eradicated, which can only have negative consequences. If more people are educated as to what effects the environment, the world has a chance to counteract the effects of pollution. The main causes of pollution are the burning of fossil fuels such as with car exhausts, littering as a result of societal norms and laziness, and factory waste as a result of lax waste regulation, and can result in mass destruction of the environment and catastrophic effects on the everyday lives of contemporary people.
The amount of factories and industries has grown immensely through the previous years which has resulted in an expansion in the consumption of petroleum products. Innovation has begun to increase and has promoted the expansion of the production of cars. As stated by the Air Quality Research Center, "Air pollution is one of the most dangerous environmental problems, causing many adverse health effects and responsible for 50,000 deaths in the U.S. each year" (Air Pollution and Health – Air Quality Research Center.).

Essay On Environmental Pollution
The environmental issue I choose is pollution. There is different types of pollution. There is water pollution, air pollution, soil pollution, thermal pollution, radioactive pollution, noise pollution, and light pollution. Every type of pollution is bad and it is causing health issues and even worst, deaths. Pollution is A very serious subject that is harmful to people and the environment. It is killing A lot of people. 4.6 million people die each year from pollution. Each year 1.2 trillion gallons of untreated sewage, stormwater, and industrial waste are dumped into US water.Pollution is one of the most biggest global killers affecting over 100 million people. Over 1 million seabirds and 100,000 sea mammals are killed by pollution every year. Approximately 40% of lakes in America are too polluted for fishing, aquatic life, or swimming. Pollution occurs when pollutants contaminate the natural surroundings. Pollution disturbs our ecosystem. Air Pollution is the most dangerous forms of pollution. It occurs due to many of reasons, excessive burning of fuel, cooking, driving and other types of activities that are similar. They release A huge amount of chemical substances in the air everyday; these pollute the air. Also smoke from chimneys, factories, vehicles or burning basically occurs due to coal burning. Air pollution is breaking down our ozone layer. There is different types of pollution but environmental pollution has been around for centuries and it is affecting the environment. People should care about this topic because pollution is a serious problem and it causes many deaths and illnesses.
The worst types of pollution are air pollution and water pollution, they don't only harm our environment but also our health. It's really scary to think about because around 15,000 people in the world each day die because of water pollution and 2.4 million people in the world die each year because of air pollution. So this is a big environmental issue. The causes of water pollution is water and sewage waste. World population is increasing each year. This is causing huge environmental and health damage. Most water pollution doesn't begin in the water it starts with what stuff filters and enters through the water.
Persuasive Essay On Pollution
Your day has been great so far. You went on vacation, you found a dollar bill on the floor, you ate your favorite dish, nothing can be better than this. As soon as you walk on the boardwalk you are hoping to see big waves and fish in the sea, instead, you see dead fish and some animals floating in the water next to old car tires, trash, and fertilizer. Now you feel terrible and want to go home. Pollution is devastating. The reason why I researched this topic is that I do not want my family nor my planet to get sick. Pollution can be stopped very easily, it's just that people "don't know" how to stop or they just don't care, which is a serious problem. I want people to see that pollution is mainly caused by humans, and also for them to see that it is a horrible thing that is happening. Some kids litter because they see their parents and their whole family doing it. When I was researching this topic, I noticed that I needed to find out more information, so I asked questions to myself. When did pollution get so bad? How many animals have gone extinct because of pollution? How many people die each year because of pollution? How much does everyone on the planet pollute each year? What is the best way to stop pollution? Can just one person make a difference? After a lot of research, I found out lots of ways that we can stop pollution, so it is possible to end it. Or at least improve the air. Pollution is caused by people littering, throwing their trash everywhere, wasting energy, and burning fuel from vehicles. Pollution effects all animals and plants from around the world. It can harm them and kill them. Some animals have gone extinct because of pollution, thanks to humans. To be exact, over 11 species of animals have gone extinct because of pollution, Not to mention people have died too! How much? Well, about 6.5 million people have mainly because of respiratory problems (lung cancer caused by air pollution) . Yea, its really bad. Pollution has been around for a long time in the U.S since the mid–19 centuries. It got worse because of the industrial revolution. This caused the air and water to become polluted because of all of the manufacturing factories, which uses coal for their factories and threw their waste

Pollution has become a major issue over the years. It has caused death, disease, and many health problems. It is a major concern of our world today and not much is being done to prevent it. If not all, a lot of pollution is caused by humans. There are different types like industrial, agricultural, etc. Many people are realizing now the threat that pollution poses to humans.
There are three main types of pollution. They are land, air, and water pollution. Land pollution deals with dumps or other harmful substances. Strip mining, digging, and irrigation are types of land pollution also. They aren't as harmful to us but they scar and hurt the land. Landfills are a major source of...show more content...
Air pollution occurs when pollutants are released into the air and cannot be taken out by its natural process. This upsets the balance of the atmospheres natural cycle.
There are two types of air pollution: indoor and outdoor. Outdoor pollution is the most harmful. Most of it is caused by motor vehicles. Some air pollution also comes from business and industrial processes. For example, many dry cleaning plants remove dirt from clothing with a chemical called perchloroethylene, a hazardous air pollutant. The burning of garbage may discharge smoke and heavy metals, such as lead and mercury, into the atmosphere. Most heavy metals are highly poisonous.
One of the most common types of outdoor air pollution is smog. Smog is a brown, hazy mixture of gases and particles. It develops when certain gases released by the combustion of gasoline and other petroleum products react with sunlight in the atmosphere. This reaction creates hundreds of harmful chemicals that make up smog.
Acid rain is another type of air pollution. It forms when the gases sulfur dioxide and nitrogen oxides react with water vapor in the air. These harmful gasses come from the burning of natural resources. Acid rain is involved in all three types of pollution. It harms plant growth and vegetation, kills marine life, and

Solid waste such as tires, diapers and plastics are buried in landfills each year. It takes generations for them to decompose. Today, there are laws that penalize manufacturing plants that dispose hazardous wastes. These plants dump these hazardous materials in nearby woods or dump them into streams (this practice was common fifty years ago). We need rain forests for survival. Rain forests pump fresh oxygen into the atmosphere, protect soil from erosion and absorb carbon dioxide. Rain forests cover 4.5 billion acres and accounts for 7 percent of the earth's land. The Amazon in Brazil is the largest rain forest (2 million acres). The fate of today's rain forest is in trouble. A process called deforestation is the leading problem. Deforestation is the process of cutting down forests to use the land for farming and grazing cattle. Farmers "slash and burn" forest turning them into desert land. Brazil promised to implement laws that were tougher to protect the Amazon. These laws cut deforestation in half. By 1994, the burning started again and in 1996 the burning was at it's worst. The ozone layer blocks harmful ultraviolet rays, that comes from the sun. Chemicals released from the earth are depleting the ozone layer. Skin cancer is on the rise as a result of the depletion of the ozone layer. Scientist states that every 1 percent of depletion of the ozone layer, the rate of skin cancer will rise 5

INTRODUCTION OF AIR POLLUTION
The chemical composition of the atmosphere today is so different as compared to the atmosphere that existed before the Industrial Revolution, 1760 – 1830. To define air pollution, we should first consider all those sources that release harmful chemicals into the atmosphere and alter its chemical composition. First of all, all anthropogenic (man–made) emissions are air pollutants. Next, is the natural emission which can be divided into biogenic and geogenic. Biogenic emissions result from the living world such as volatile organic compound emissions from forests and CH4 emissions from swamp. On the other hand, geogenic emissions are from the non–living world, such as volcanic emissions, sea–salt emissions, and...show more content...
