Introduction:-
I'm going to talk about pollution. I choose this subject because I want to know more about pollution. So in my report I will talk about four things:-

[IMG]file:///C:/Users/rr/AppData/Local/Temp/msohtmlclip1/01/clip_image001.gif[/IMG] What is pollution.
[IMG]file:///C:/Users/rr/AppData/Local/Temp/msohtmlclip1/01/clip_image001.gif[/IMG] Air pollution.
[IMG]file:///C:/Users/rr/AppData/Local/Temp/msohtmlclip1/01/clip_image001.gif[/IMG] Land pollution.
[IMG]file:///C:/Users/rr/AppData/Local/Temp/msohtmlclip1/01/clip_image001.gif[/IMG] Water pollution.
What is pollution:
Pollution is when water, air or land becomes very dirty. Pollution can come in 4 different types effecting different types of areas in the world. Air pollution effects the air, water pollution effects the water and marine life, land pollution effects the land destroying life and the environment and there is also noise pollution that can effect our hearing. We all contribute to pollution in some way or another. Whether it be with a large amount or small amount we can still cause major damage to our health and the environment. Although we all contribute to help stop the increase of pollution. Very little people realize that pollution is very harmful because they don't think of the environment, themselves and other people and what it can do. Pollution is an important factor to our lives. It involves our society and all other animals. Pollution is gradually destroying our planet and is gradually killing ourselves too. Like air pollution, smog and acid rain is a killer to all of us. It destroys marine life, our own health and destroys historical monuments and statues.








Air pollution:
Air pollution is a major problem effecting the entire world especially when we start burning forests which are the main source to oxygen (O2). Air pollution is very harmful it is destructive to living organs. The air is made of mainly of oxygen and nitrogen but it also contains tiny amounts of other gasses such as carbon dioxide, hydrogen and helium. most of it is nitrogen.
We all contribute to air pollution in some way or another. Whether it be with a large amount or small amount we can still cause major damage to our health and the environment. Although we all contribute to help stop the increase of air pollution.
Land Pollution:
Mismanagement of the land will cause is becoming a big problem. The pollution it causes are soil erosion, degradation and Stalinization are just a few other problems facing the state of our land. The causes are losing 6 hectares of land every year and losing 24 billion tons of top soil. Globally we are losing a minimum of 15 million acres of prime agricultural land to overuse and mismanagement every year.
Desertification is threatening about one third (sixteen million square miles) of the world’s land surface.

Water Pollution:
Water covers 70% of the earth and only 3% of fresh water. 1% of fresh water and 2% of frozen fresh water. Pollution is a major cause to life. It impacts on marine life and is a major impact to life in the whole world.
Subsequently, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate. In addition to innocent organisms


dying off, our drinking water has become greatly affected as is our ability to use water for recreational purposes. In order to combat water pollution, we must understand the problems and become part of the solution.
Causes of water pollution
Many causes of water pollution including sewage and fertilizers contain nutrients such as nitrates and phosphates. In excess levels, nutrients over stimulate the growth of aquatic plants and algae. Excessive growth of these types of organisms consequently clogs our waterways, use up dissolved oxygen as they decompose, and block light to deeper waters.

The pollution is also caused when silt and other suspended solids, such as soil, wash off plowed fields, construction and logging sites, urban areas, and eroded river banks when it rains. Under natural conditions, lakes, rivers, and other water bodies undergo Eutrophication, an aging process that slowly fills in the water body with sediment and organic matter. When the sediments various bodies of water, fish and other marine life respiration becomes impaired. Pollution in the form of organic
material enters waterways in many different forms as sewage, as leaves and grass clippings, or as runoff from livestock feedlots and pastures.

When natural bacteria and protozoan in the water break down this organic material, they begin to use up the oxygen dissolved in the water. Many fish or other marine life can not survive when oxygen levels drop below two to five parts per million. When this occurs, the fish will gradually die and the food chain will get disrupted meaning the marine life will gradually disappear.
