Air Pollution is an addition of harmful substances to the atmosphere resulting in disablement to the environment, human health, and quality of life. One of many forms of contaminant, air taint occurs inside homes, schools, and offices; in cities; across continents; and even sphericly. Air pollution makes people sick, it causes breathing problems and promotes cancer, and it harms adjusts, animals, and the ecosystems in which they live. Some air pollutants submit to earth in the form of acid rain and snow, which deplete statues and buildings, damage crops and woodwind instruments, and make lakes and streams unsuitable for fish and other plant and animal life.
Pollution is changing the earths atmosphere so that it lets in more harmful radiation from the sun. Scientists predict that the temperature increase, referred to as global warming, will affect world food supply, alter sea level, make weather more extreme, and increase the spread of equatorial disease (Wikipedia, 2007).
Most air pollution comes from human activities: hot fossil fuels, natural gas, coal, and oil to power in make cleanrial processes and aim vehicles. Among the harmful chemical compounds this burning puts into the atmosphere are degree Celsius dioxide, carbon monoxide, nitrogen oxides, sulfur dioxide, and tiny solid particles including twist from gasoline additives called particulates (Wikipedia, 2007).
Between 1900 and 1970, motor vehicle use quickly expanded, and emissions of nitrogen oxides, some of the most damaging pollutants in vehicle exhaust, increased 690 percent. When fuels are incompletely burned, various chemicals called volatile perfect chemicals also enter the air. Pollutants also come from other sources. For example, forest fires emit particulates and Volatile organic chemicals into the atmosphere. Ultra fine dust particles, dislodged by soil erosion when water and weather free layers of soil, increase airborne particulate levels. A big volcanic eruption can darken the sky over a wide...
