Air pollution and global warming essay
Air Pollution Causes, Effects, and Solutions
There is enough evidence of the fast rate at which the environment is getting damaged. Human beings are at the fore front as the major contributors of the causes of environmental concerns. The problem is that every body seems to be talking about the need to conserve our environment, but no one seems to do anything about it. In this paper, I discuss two global environmental concerns- global warming and water pollution, examining their causes and solutions to the problems.

Events like this alerted humans of the threats air pollution poses to human health. In 1963 several federal and state laws were passed including the original Clean Air Act, this produced funding to study the effects and help clean up air pollution. In 1970 Congress passed a stronger Clean Air Act and created the Environmental Protection Agency, known as the EPA. Again in 1990 Congress expanded the Clean Air Act, which gave the EPA more authority to implement regulations lowering pollutant emissions. Worldwide, many countries have taken steps to reduce or limit greenhouse gas emissions to combat global warming. The Kyoto Protocol, first adopted in Kyoto, Japan, in 1997, is an agreement between 183 countries that they will work to reduce their carbon dioxide emissions. The United States has not signed that treaty (National Geographic Education, 1996) . Along with human health, automobiles pose a threat to the environment in ways of global warming, water pollution, and acid rain. Global warming is affected by the greenhouse gases, like carbon dioxide, which are emitted through automobile exhaust. Vehicles require fluids like motor oil, antifreeze, gasoline, and refrigerants.
