Even though we as a nation can prevent some of these Atmospheric Issues it will take time; however, in the mean time Atmospheric Issues are dangerous. If we do not do something soon the effects of Atmospheric Issues well continue to progress. Atmospheric Issues has been the cause of air pollution, global warming, ozone depletion, greenhouse gases, and acid deposition. Stratospheric ozone reduction has been a air pollutant problem for some time. Stratospheric ozone weakening is a threat to our ecosystems, and human health as well. In this paper I will explain the problems, and I will give possible solutions. Air Pollutants & Possible Solutions Air pollutants are substance is the air that can potentially cause harm to humans, and the environment. Pollutants can be in the forum of liquid, solids, and gases. Pollutants can also be natural, or man made. There are two types of pollution; primary pollution which is cased by human activity, and the secondary pollutants that are reactions to primary. According to U.S. Environmental protection agency (2009), “Sulfur dioxide (SO2) is one of a group of highly reactive gasses known as “oxides of sulfur.” The largest sources of SO2 emissions are from fossil fuel combustion at power plants (66%) and other industrial facilities (29%). Smaller sources of SO2 emissions include industrial processes such as extracting metal from ore, and the burning of high sulfur containing fuels by locomotives, 2

large ships, and non-road equipment. SO2 is linked with a number of adverse effects on the respiratory system.” Short-term exposures to SO2 can cause bronchoconstriction, and increased systems of asthma i.e. wheezing, chest tightness and shortness of breath. Sulfur dioxide and nitrogen oxides NO2, forms H2SO4, together forums acid rain. Which are found in stream, lakes, soil, corrosion of buildings and monuments, and anything else that is permanently out doors.) Europe has already lost approximately 22% of its total forest to acid rain. This is a major problem. It is not a potential problem; it is actually happening. In the United Kingdom about 57 % of its forest has been damage. Sulfur Dioxide (SO2) affects some 600 million people living in urban areas. It is said that sulfur dioxide (SO2) levels exceed World Health Organization guidelines in most urban areas. Over 125 million people live in cities, states, and countries with extremely high levels of
