Automobile Air PollutionEfforts to improve the standard of quick for humans, through the control of character and the development of new products have also issueed in the pollution of the environment. Much of the worlds air, water, and land is straight partially poisoned by pollution. both(prenominal) places have become uninhabitable. This pollution exposes people all around the globe to new risks from disease. Many species of plants and animals have become endangered or are now extinct. The air pollution comes from lots of sources but the paper will be about air pollution cause by automobiles. As a result of tremendous amount of air pollution, primarily for automobile governments have passed laws to limit or reverse the threat of environmental pollution. There are lots of sources other than the automobile for air pollution. Nature itself is one of the causes. Sometime nature causes the air pollution by activities like a forest fire, volcanic, hurricane. These are temporary dis locations that nature balances and accommodates to modern economic development, however, sometimes disrupts natures delicate balance. The other source is from factories. Factories are release smokes and chemical in the air. In many places smoke from factories and cars combines with naturally occurring haze to form smog and create a midday sky. It had happened in London, London, England, has been subjected to the danger of smog, long recognized as a potential cause of death, especially for cured persons and those with severe respiratory ailments (pollution). Transportation by car though, is the major source of air pollution. Early in the century human invented, internal combustion locomotive, engine that use fuel as gasoline or diesel. Those engines were used to manufacture an automobile for fast travel from one place to another. Because they were not much in use, those few cars were not enough to threat the environment. Those engines were not fast enough so mastermind humans inve nted bigger and faster engines and those take more fuel. When these engines shine fuels they introduce smoke and other, less visible, by products. Once they are released into the air, the products of incomplete combustion, particulate matter (soot, ash, and other solids), unburned hydrocarbons, carbon monoxide, sulfur dioxide, various nitrogen oxides, ozone, and lead, bear with a series of chemical reactions in the presence of sunlight. The result is the dense haze characteristic of smog. Smog may appear brownish in ruse when it contains high concentrations of nitrogen dioxide, or it may look blue-gray when it contains large amounts of ozone (Danger).
