unrivalled of the biggest threats to human health and the surround is caused by the build up of ozone gas at ground level. This buildup of ozone gas is known as photochemical or summer smog. It is called summer smog because it is worse in summer because sunlight plays a role in the creation of ozone gas. Ozone is created when "car and industry emissions such as azotic oxides and organic compounds react with oxygen under strong sunlight" (AirWatch, 2003, 1).
Acid rain is another major threat to the environment and human health. Acid rain is formed by a chemical reception that involves chemicals that all come from the generation of electric power that use fossils fuels; sulfur dioxide and nitrogen oxides. This chemical reaction occurs when such gases react in the atmosphere with water, oxygen, and other chemicals to get ahead acidic compounds, forming a mild sulfuric acid and nitric acid solution (Acid, 200
3, 2). there are then dry and wet forms of this acid solution. Winds splay both forms distances that often range hundreds of miles. Both forms are risky to plants and animals, including humans. The wet form is deposited through acid rain, fog, and snow. The dry form is deposited through gases and particles into water, soil, and onto cars, homes, and plants.
Acid rain pollutes our soils and water sources. It destroys our forests and it causes human health damage. It also has a negative impact on our look for and wildlife. Efforts to reduce Acid Rain include the Acid Rain Program which caps sulfur dioxide emissions from power plants at 8.
95 million lots annually, allows plants to trade S02 allowances, and reduces nitrogen oxide emission rates (Acid, 2003, 3). Many authorities efforts have been made to reduce other forms of air pollution like photochemical smog. Many of these efforts have fallen utter nearly short of targets. For example, in some of China's cities, particulate levels are more than six times higher than World health organic fair play Guidelines (Rising, 1998-99, 1).

One of the most significant pieces of legislation in the U.S. that is designed to maintain close air quality standards is known as The Clean Air Act (1977). The Clean Air Act was signed into law to control air pollution. It sets air quality standards and emissions caps. It provides ozone layer protections and involves measures to prevent significant deterioration of air quality. The Act also calls for abstemious fuel vehicles a
