spread pollution - research Paper ExampleCurrently, automobiles are the largest contributor to the formation of ground level ozone therefore there is a need to increase usage of alternative sources of transportation in order to reduce levels of O3 air pollution.Air pollution has become a major environmental health problem affecting both true and developing countries throughout the world (Nadakavukaren, 2006). The consequence has been that air pollution is causing human health problems as well as damage to vegetation, crops, wildlife, materials, buildings and even the climate. In the U.S., the largest sources of air pollution, in order of importance, are 1) transportation, principally automobiles and trucks 2) electric power plants that bum coal or oil and 3) industry, for which the major sources include steel mills, admixture smelters, oil refineries, and paper mills (Nadakavukaren, 2006). The most common air pollution problem resulting from these emission sources is ground-leve l ozone (O3), accord to the United States Environmental Protection Agency (EPA), non-attainment of EPA requirements for O3 is the most common air pollution problem confront large cities in the U.S (Crpc-La.org, 2011). It is estimated that, 160 million people in the U.S. lived in areas that are in non-attainment of good O3 levels (Organization for Economic Co-operation and Development OECD, 2005).In the past, efforts to reduce air pollution have consisted primarily of command and cover programs that involve enforcement of government regulations designed to reduce toxic emissions. Such programs have proven highly powerful in reducing industrial, point source pollution and causing auto manufacturers to produce cleaner vehement automobiles (Environmental Protection Agency EPA, 2011a). While these government controls continue to effectively lower industrial emissions and reduce pollutants emitted from vehicles, O3 precursor, NOx, continues to be emitted into the air at increasing l evels.
