I. INTRODUCTION

Pollution is a major global concern because of its harmful effects on the person’s health and on the environment. Everyone is affected as we are all inhabitants of this one and only place we call home, our planet Earth. Each person has something to contribute to prevent its further deterioration, to help ourselves, the children and ensuring a sustainable future for generations to come. We can help combat pollution in our own immediate environment if we are aware of the nature and form of pollutions and its effects on us and the environment.

A pollutant is a waste material that pollutes air, water or soil. Three factors determine the severity of a pollutant, its chemical nature, the concentration and the persistence. There are two main categories of pollutants. Biodegradable pollutants are materials, such as sewage, that rapidly decompose by natural processes. These pollutants become a problem when added to the environment faster than they can decompose. Non-degradable pollutants are materials that either do not decompose or decompose slowly in the natural environment. Once contamination occurs, it is difficult or impossible to remove these pollutants from the environment.

SMOG OVER SANTIAGO

Set in an enclosed valley between the coastal range and the Andes Mountains, Santiago, Chile, experiences high levels of air pollution. Vehicular and industrial emissions, street dust, thermal inversions and the city’s location all contribute to the problem. Since 1993 the Chilean government has been working with an agency in the United States to improve air quality in Santiago.

...years the problem of pollution has become very acute. It is the industrialized west which takes it seriously, because it is suffering from its injurious effects. In India, sufficient attention has not been paid to it so far. If we do not tackle this problem now, future generations will suffer from the harmful effects of pollution. This problem assumes different forms such as Air pollution, Water pollution, Soil pollution, Noise pollution and Paper pollution. All this pollution results from the greed of man for getting more and more money. Trees have been cut down, on an unprecedented scale and large production by industrialization has assumed gigantic proportions. So the main cause of air and water pollution is unbalanced industrial growth and urbanization and deforestation. The owners of industries dump waste material on the surface of the earth or in rivers. So, water is polluted and the waste on the earth produces different poisonous gases which pollute the air. On the other hand, forests where purity air have been cut down and new cities and industries have been established in their place. The cutting of the forests causes what is called "The Green House Effects". It results in the heating of the earth's surface which has serious consequences for life on this planet. As a result, generations to come are likely to suffer from a number of incurable diseases. Timely measures must be taken to prevent the 'Green House Effect'. Paper pollution of public life and......

...countries of the world. Often, these countries have extremely poor environmental situations. In many Third World nations, pollution is unrestricted. Countless other environmental problems are also not addressed by the government. Usually, creating and enforcing environmental regulations would be economically disastrous for a poor country. As a result, it is forced to choose between buying food and having a clean environment. Often, rich Western countries take advantage of the dilemma of Third World countries. They dump garbage and hazardous waste in developing countries. First World companies might also build plants, which emit considerable pollution, in Third World nations to avoid the regulations these companies would face at home. Some transnational corporations that produce chemicals deemed overly dangerous in the First World find a market in the Third World. There, governments cannot restrict usage of these chemicals because it would be too costly to citizens trying to make a living. Countries in Latin America, Eastern Europe, Africa, and Asia are the greatest victims of this environmental inequality. In addition to problems created by development and industrialization, poorer nations also suffer environmental difficulties caused by poverty and war, among other causes. Many environmental problems arise in the Third World. Air pollution, water pollution , deforestation, desertification, soil erosion, and poisoning of the environment are among the largest of these.......

This includes land, water, and air. Of all the First World countries, the United States is the most polluting nation on Earth. The United States is ranked seventh on pollution control, by only spending 60% of its Gross National Product to help the environment. As a nation we have spent over 120 billions of dollars a year on research and development. The majority of the cost incurred has come from Environmental Quality, our country has consumed over 98 quadrillion Btu of energy in the year 2000 alone. Americans generate five pounds of solid waste every day, creating one ton of solid waste each year. In an average day in the United States, we throw out 200,000 tons of edible food and have thrown 1 million bushels of litter out of our automobiles. The main human contributor for pollution are landfills. It is possible that land pollution can contaminate the air and/or the water. Water pollution is the action of environment......

...for Help Pollution is caused by many day to day activities that we don’t even notice. There are also different types of pollution, but they all result in the same thing, earth is slowly dying. Pollution is harmful to both the environment and the creatures that inhabit it, including humans. If you are wondering what the most harmful causes of pollution are, look no further, because you should consider the terrible causes of air pollution, sewage, and oil spills, as well as the effects that they have on the environment. Air pollution is one of the most common ways that the earth is polluted. Air pollution is caused by many things including exhaust fumes from cars, manufacturing factories and the household and farming chemicals. The fuel that is used in cars includes fossil fuels, which emit carbon dioxide into the air, causing global warming. Power plants also burn oil and coal, which releases poisonous gases into the air, which may result in acid rain. Air pollution effects many people across the world as well as the environment. “Health experts have known for years that air pollution increases the risk of a wide range of ailments, including respiratory problems and heart disease. Some compounds in the air we breathe, such as diesel exhaust, have already been deemed cancer-causing.” (Barboza). It is not only a major risk to health, it’s also a leading environmental cause of cancer death. There were 220,000 people that died of lung cancer due to air pollution in......

...There are two types of the cause of pollution, natural and man-made. Natural pollution occurs naturally and won't cause excessive harm to our lives due to its regeneration ability. While the man-made pollution is caused by human activities, and hard to get rid of. The backbones of man-made pollution are human population and technology. Naturally human needs contact to the environment, we get resources from nature. This is for the sake of living. By the increase of human population, the contact is getting more intensive, because needs are increasing. And by the findings and development of new technologies, human can apply them to get the resources. And it's common that new technologies would bring their respective side effects besides their advantages. Water Pollution Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives (in) it. When humans drink polluted water it often has serious effects on their health. Water pollution can also make water unsuited for the desired use. Water pollution is usually caused by human activities. Different human sources add to the pollution of water. There are two sorts of sources, point and nonpoint sources. Point sources discharge pollutants at specific locations through pipelines or sewers into the surface water. Nonpoint sources are sources that cannot be traced to a single site of discharge. Examples of point......

...Nowhere on Earth is free from environmental pollution. It has been becoming more and more serious these days. This makes us think a lot. So what is the cause of this terrible matter? And what is the bad consequence it led to? Let’s try to find out. There’re many kinds of pollution such as air pollution, water pollution... that should be tackled as soon as possible. In Ho Chi Minh City, air tests show that air brings many high risk of health problems for people living here. Dust floats in the air is the top actor that pollutes the air seriously. Many lakes, rivers are getting polluted by the toxic waste from factories as well as daily activities, which has not been treated properly. The results of recent surveys have showed that the amount of heavy metal in soil has been increasing in recent years. Not only that but people also find out that the soil contains a large amount of redundant pesticide in many places. So what is the cause of these current situations? First of all, it’s the lack of common sense of protecting the environment. The bad condition of environment has been due to the poor awareness of many people. Some people think protecting environment is the responsbility of government, not theirs. Others think what they have done is so small that it’s not enough to harm the environment. Another cause of pollution is business’s lack of responsbility. Because of profits, many businesses have offenced the production process, that contributes to cause the pollution.......

...Pollution is a major problem in the world. Many people don’t understand that what they are doing has consequences. Throwing your plastic water bottles away? Try recycling them. If it goes to a landfill, it will take it nearly a decade to decay. If it is incinerated, harmful pollutants will enter our atmosphere. However, if it is recycled, it can be reused and help to save the planet. Trash enters waterways as well. This trash kills and destroys aquatic ecosystems. Animals eat the trash and die. Water is polluted and aquatic species and effected. What we need is a worldwide effort to prevent pollution. Our trees are being cut down rapidly. Our earth is becoming warmer. If pollution continues, the day is not far when our earth will be a boiling pan and become a desert. Or it will be covered with sea water causing the death of all mankind. Pure air is always needed for inhaling. If we take pure air, our health improves. On the other hand impure air causes diseases and impairs our health and causes our death. Smoke pollutes the air. It is the root of air pollution. The smoke which is discharged from industries, automobiles and kitchens is the mixture of carbon monoxide, carbon dioxide, methane, and other poisonous gases. These cause lung-cancer, tuberculosis, and other diseases which take a heavy toll of human life. We need to fight alongside one another to make a difference and save our beautiful planet. Together, we can and we will save the world. I recommend we create strict......

...INTRODUCTION Environment, encompasses all living and non living things occurring on Earth or some region thereof and the interaction of all living species. Types of Environment: (i) Natural environment: It includes air, water, light, soil, forests, plants, and animals etc. (ii) Artificial environment: The objects of our surrounding which are manmade are artificial environment. (iii) Biological environment: It includes all living organisms that surround us. ENVIRONMENTAL POLLUTION Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem. Pollution leads to depletion of the ozone layer, global warming and climate change. Pollution can take many forms. The air we breathe, the water we drink, the ground where we grow our food, and even the increasing noise we hear every day—all contribute to health problems and a lower quality of life. TYPES OF POLLUTION WATER POLLUTION NOISE POLLUTION LAND POLLUTION AIR POLLUTION AIR POLLUTION It is defined as the presence in the atmosphere of one or more contaminants in such quality and for such duration as is injurious, or tends to be injurious, to human health or welfare, animal or plant life. Industries, vehicles, increase in the population, and urbanization are some of the major factors responsible for air pollution.

...Markquice Carson 11-27-12 Portfolio Report Indu/Agri/Mun Pollution Dr. Buckner There are a bundle of problems in America today involving pollution in every from, and this bring about solutions to solving these problems. There are several technologies to manage waste pollution. These technologies include recycling, incineration, and sanitary landfills. This will strictly discuss the problem, Methods/Technology, and Beneficial aspects of Incineration. Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash, flue gas, and heat. The ash is mostly formed by the inorganic constituents of the waste, and may take the form of solid lumps or particulates carried by the flue gas. The flue gases must be cleaned of gaseous and particulate pollutants before they are dispersed into the atmosphere. In some cases, the heat generated by incineration can be used to generate electric power. There are several types of incineration technologies: Rotary-kiln, Burn Barrels, Fixed grates the typical amount of net energy that can be produced per ton municipal waste is about 2/3 MWh of electricity and 2 MWh of district heating. Thus, incinerating about 600 metric tons (660 short tons) per day of waste will produce about 400 MWh of electrical energy per day (17 MW of......

...Environment pollution is the mixing of harmful pollutants into the environment causing disturbance to the natural processes and cycles. Various types of environmental pollution are categorized as the water pollution, air pollution, land pollution and noise pollution. Production of solid and liquid wastes on large scale from the industries, emissions of hazardous gases, deforestation, global warming, and many more problems originated by the human beings are the main reasons of increasing the environmental pollution. In the last one decade, there is a great increase in the level of environmental pollution and scenario has become worse than earlier. In the whole universe, there is only one planet named earth provides facility of all basic elements required for the life existence. It gives us life and what we give it, pollution. However, it was much better that if we give it nothing but we give it pollution and contamination regularly. As we all live on this planet, we all are highly responsible for the maintenance of the earth. However, we all forget our responsibility and busy in our daily routine and competitions to just fulfil our needs in anyways. Fresh air and clean water are two most basic needs to sustain life but nothing of both is possible in the modern time. It seems that, after some decades here would be no man, no plants, no animals and no life. All the natural gases in the environment make their balance by reacting each other. Some of them are used as a food by......

...Activities such as bathing and washing clothes near lakes, ponds or rivers add nutrients like nitrogen into the water bodies. Land Pollution These chemicals come from industrial activities and from bad waste disposal. Soil pollution may cause health risks. They include the sound of vehicles, loud speakers, etc. Noise pollution can cause ear problems or even permanent deafness. Noise Pollution Air Pollution Water Pollution Pollution Pollution Facts & Types of Pollution by Alina Bradford, Live Science Contributor   |   March 10, 2015 10:05pm ET Pollution is the process of making land, water, air or other parts of the environment dirty and unsafe or unsuitable to use. This can be done through the introduction of a contaminant into a natural environment, but the contaminant doesn't need to be tangible. Things as simple as light, sound and temperature can be considered pollutants when introduced artificially into an environment.  Toxic pollution affects more than 200 million people worldwide, according to Pure Earth, a non-profit environmental organization. In some of the world’s worst polluted places, babies are born with birth defects, children have lost 30 to 40 IQ points, and life expectancy may be as low as 45 years because of cancers and other diseases. Read on to find out more about specific types of pollution. Land pollution Land can become polluted by household garbage and by industrial waste.

...Pollution in Its Many FormsOne of the most serious problems facing the world today is pollution, that is the contamination of air, land and water by all kinds of chemicals such as poisonous gases, waste materials and insecticides. Pollution has upset the balance of nature, destroyed many forms of wildlife and caused a variety of illnesses. It occurs in every country on Earth but is most prominent in industrial countries.Breathing polluted air is very common to most people, especially those living in cities. In heavily industrialized areas, fumes from car exhausts and thick smoke from factory chimneys can be seen darkening the atmosphere. This would reduce visibility and make the air unpleasant to breathe. Large scale burning of fossil fuels, such as coal, gas and oil, in homes and industries also produces a wide range of pollutants. This includes sulfur dioxide which damages plants, destroys buildings and affects health. Other known pollutants are carbon monoxide, nitrogen dioxide and dirt particles. The fumes produced by car exhausts and factories would normally disperse in the air, but sometimes they are trapped by air layers of different temperatures. The result is a fog-like haze known as smog.The motor car is a major source of pollution. In densely populated cities where there are millions of cars on the roads, the level of carbon monoxide in the air is dangerously high. On windless days, the fumes settle near ground level. Fumes from car exhausts also pour out lead and......

...ENVIROMENTAL POLLUTION Environmental pollution is the biggest menace to the human race on this planet today. It means adding impurity to environment. The environment consists of earth, water, air, plants and animals. If we pollute them, then the existence of man and nature will be hampered. It is true that trees are being cut down rapidly. Our earth is becoming warmer. If pollution continues, the day is not far when our earth will be a boiling pan and become a desert. Or it will be covered with sea water causing destruction of mankind. Pure air is always needed for inhaling. If we take pure air, our health improves. On the other hand impure air causes diseases and impairs our health and causes our death. Smoke pollutes the air. It is the root of air pollution. The smoke which is discharged from industries, automobiles and kitchens is the mixture of carbon monoxide, carbon dioxide, methane etc. These are all poisonous gases. These cause lung-cancer, tuberculosis etc. which take a heavy toll of life. The glaring incident is the Bhopal gas leak in December 1984. Thousands of the residents of Bhopal died due to lungs problem which was caused by methylamine gas from the Union Carbide Plant. The garbage emitting foul smell, the decaying plants and animals also cause air pollution. Hence the doctors advise the patients having lungs trouble to settle in some rural places because the air of villages is pure and free from population. Then comes sound pollution. The harsh sounds of...
