ontinue to use dirty water, that disease will spread to unimaginable levels. h1 align=center> Air pollution

Pollution itself is a very broad category, and there are many different kinds of pollution. One of those is air pollution. Air pollution is probably the longest lasting type of pollution there is. Because of the Industrial Revolution, factories spewed out smoke and chemicals that had never been in contact with human lungs before. To this day the same problem remains. Air pollution, although regulated, cannot be contained in many cases. In certain areas of the world, air pollution is out of control. p> Air pollution occurs when wastes dirty the make the air dirty. People produce most of the waste that cause air pollution. Such waste can be in the form of gases or be particulates (Particles of solid or liquid manner). These substance result chiefly from burning fuel to power motor vehicles and to heat buildings. industrial processes and the burning of garbage also contribute to air pollution. Natural pollutants include, pollen, soil particulates, dust, and naturally occuring gases. Also more causes of air pollution are forms of transportation such as automobiles, airplanes, ships, and trains. p> It is the immediate effect of air pollution on urban atmospheres that is most noticeable and causes the strongest public reaction. The city of Los Angeles has been noted for both the extent of its air pollution and the actions undertaken for control. Los Angeles lies in a coastal plain, surrounded by mountains that restrict the inward sweep of air and that separate a desert from the coastal climate. Fog moving in from the ocean is normal to the city. Temperature inversions characterized by the establishment of a layer of warm air on top of a layer of cooler air prevent the air near the ground from rising.

Air Pollution has a negative impact on water quality. For the past 30 years, scientists have collected a considerable amount of convincing information demonstrating that air pollutants can be deposited on land and water, sometimes at great distances from their original sources, and can be an important contributor to declining water quality. These air pollutants can have undesirable health and environmental impacts, such as contaminated fish, harmful algal blooms, and unsafe drinking water. Researchers had found the sources of these air pollutants. They have worked diligently to improve the environment. p> Factory and business owners have the ability to prevent air pollution. The government should take action, requiring equipment to cut down on hydrocarbons in the atmosphere. The little spent regulating equipment used in factories can go a long way saving billions on health problems and other related issues. Background Over 150 million people in the United States live in areas where the Environmental Protection Agency considers the air to be unhealthy. Air pollution is the presence in the atmosph...
