Research: Project Pollution/ Go Green  Pollution - contaminants being released into an environment causing harm  `  Kenyatta Easter There are many different chemical substances that contribute to air pollution. These chemicals come from a variety of sources. Among the many types of air pollutants are nitrogen oxides, carbon monoxides, and organic compounds that can evaporate and enter the atmosphere. There are nine basic types of environmental pollution, and each one has detrimental affects on wildlife, human habitation, and the quality of life in the affected area. Air Pollution [|Air pollution] is defined as any of the atmosphere that disturbs the natural composition and chemistry of the air. This can be in the form of particulate matter such as dust or excessive gases like carbon dioxide or other vapors that cannot be effectively removed through natural cycles, such as the [|carbon cycle] or the nitrogen cycle. Water Pollution [|Water pollution] involves any contaminated water, whether from chemical, particulate, or bacterial matter that degrades the water’s quality and purity. Water pollution can occur in __oceans__, rivers, lakes, and underground reservoirs, and as different water sources flow together the pollution can spread. []  In my personal opinion I think the cause of most of the pollution in Derry township is all of the things that we have such as the chocolate factory the Reese's factory and Hershey park. **  Kayla Ashlea Williams:   **  One of Hershey's biggest Pollution Sources is the Chocolate Factory. I think that this is one of Hershey Biggest Pollutants because our Factory's are polluting the air. Global Warming People! Yes, Hershey in some area's are good about cleaning up litter that is placed on the ground. Mean while the other area's that are being more polluted need Trashcan's and Recycling bins placed in this area's. If there are still pollution problems then I think that we should have clean up groups to help to clean up area's around Hershey. Some websites that I think that you should check out to see what I am talking about ( THE HERSHEY POLLUTION PROBLEMS) meaning evidence that the Hershey Factory's are causing pollution in the air.: []**  David Sickler  ****__Indoor air pollution__**There are many sources of indoor air pollution. Tobacco smoke, cooking and heating appliances, and vapors from building materials, paints, furniture, etc. cause pollution inside buildings. //Radon// is a natural radioactive gas released from the earth, and it can be found concentrated in basements in some parts of the United States. **__Outdoor Air Pollution__** is a type of large-scale outdoor pollution. It is caused by chemical reactions between pollutants derived from different sources, primarily automobile exhaust and industrial emissions. Cities are often centers of these types of activities, and many suffer from the effects of smog, especially during the warm months of the year. Another consequence of outdoor air pollution is. When a pollutant, such as sulfuric acid combines with droplets of water in the air, the water (or snow) can become //acidified//. The effects of acid rain on the environment can be very serious. It damages plants by destroying their leaves, it poisons the soil, and it changes the chemistry of lakes and streams. Damage due to acid rain kills trees and harms animals, fish, and other wildlife.

The **Greenhouse Effect,** also referred to as global warming, is generally believed to come from the build up of carbon dioxide gas in the atmosphere. //Carbon dioxide// is produced when fuels are burned. Plants convert carbon dioxide back to oxygen, but the release of carbon dioxide from human activities is higher than the world's plants can process. The situation is made worse since many of the earth's forests are being removed, and plant life is being damaged by acid rain. Thus, the amount of carbon dioxide in the air is continuing to increase. This buildup acts like a blanket and //traps heat// close to the surface of our earth. Changes of even a few degrees will affect us all through changes in the climate and even the possibility that the polar ice caps may melt. (One of the consequences of polar ice cap melting would be a rise in global sea level, resulting in widespread coastal flooding.)
 * Ozone depletion** is another result of pollution. Chemicals released by our activities affect the //stratosphere//, one of the atmospheric layers surrounding earth. The ozone layer in the stratosphere protects the earth from harmful //ultraviolet radiation// from the sun. Release of //chlorofluorocarbons// (CFC's) from aerosol cans, cooling systems and refrigerator equipment removes some of the ozone, causing "holes"; to open up in this layer and allowing the radiation to reach the earth. Ultraviolet radiation is known to cause skin cancer and has damaging effects on plants and wildlife. **__Black Carbon Pollution__**Black carbon pollution is the release of tiny **particles** into the air from burning fuel for energy. Air pollution caused by such particulates has been a major problem since the beginning of the //industrial revolution// and the development of the //internal combustion engine// . Scientific publications dealing with the analysis of soot and smoke date back as early as 1896. Mankind has become so dependent on the burning of **fossil fuels** (petroleum products, coal, and natural gas) that the sum total of all combustion-related emissions now constitutes a serious and widespread problem, not only to human health, but also to the entire global environment.  //Lawrence Berkley national Laboratory//.
