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 the burning of trash in the form of particles or gases. Air Pollution is a harmful substance 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 causes depletion of the ozone layer, which allows a greater amount of ultraviolet rays to earth, which can be harmful to humans. Some air pollutants return to earth in the form of acid rain, which can corrode statues and buildings, damage crops, forests, make lakes, and streams unsuitable for fish and other plant and animal life. Smog is another result of air pollutants in the form of fog that is harmful to humans. Global warming can also be caused by air pollutants, which cause the earth's temperatures to increase. This affects 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 the 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 Environment A Global Challenge, " The highest regions of the stratosphere contain about 90% of all ozone." (n.p.) The sun's 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. Some countries stop the usage of CFCs others continues to use this hazardous chemical.
