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
Mentioned by the web page of Understanding Acid Rain, ( acid rain is a result when sulphur dioxides and nitrogen oxides are carried by the wind and deposited on the earths surface. As The Environment A Global Challenge explains ( In London, street lights were turned on by noon because smog darkened the midday sky. About 1 million of these people will die. Air pollution has been increasing since the Industrial Revolution . At this point , intense ultraviolet radiation (UV-rays) breaks the CFC molecules apart, releasing the chlorine atoms they contain. Although the effects of future climate change are unknown, some predict that exaggerated weather conditions may translate into better agricultural yields. Global warming is another effect from air pollution . Global warming is also known as the greenhouse effect . ) Other gases such as methane, nitrous oxide, and chlorofluorocarbons , admit the sun's light but tend to reflect back downward the heat that is radiated from the ground below, trapping heat in the earth's atmosphere . For the very young, the very old, and people who suffer from asthma or heart disease, the effects of smog are even worse . Many of the worlds animal life may become extinct, because of shifting of their habitat.
