AIR POLLUTION

What causes air pollution? Air pollution results mainly from the incomplete combustion of several fuels, such as coal, petrol and wood. The primary sources of pollution from combustion are furnaces in factories, engines in vehicles and burning of trash, in the form of particles or gases. Air Pollution is a harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life. One of many forms of air pollution occurs inside homes, schools, offices, in cities , across continents and even globally. Air pollution causes damage to the environment. Air pollution cause depletion of the ozone layer, which allows a greater amount of ultraviolet rays to earth, that can be harmful for humans. Some air pollutants return to earth in the form of acid rain , which it can corrode statues and buildings, damage crops, forests, makes lakes, and streams unsuitable for fish and other plant and animal life .Smog is another result from air pollutant which is in the form of fog that is harmful to humans. Global warming can also be a cause by air pollutants, which causes the earth temperatures to increase. This effects the whole earth as one , and leading to a rise in global average temperatures. Air pollution is changing the earth’s environment , if we continue polluting we can have serious consequences that can change the earth and health of humans. Ozone is a gas made up of three oxygen’s which produces O3 . The ozone layer is found in the stratosphere found about 30 miles above the earth. According to the website The Environment A Global Challenge “ The highest regions of the stratosphere contain about 90% of all ozone.” (n.p.) The suns rays are absorbed by these ozone molecules, which keeps the rays from reaching the earth. . The main pollutant is chlorofluorocarbons (CFCs) which is the major cause of depletion of the ozone layer.
