ACID RAIN
1. Acid rain is rainfall created by pollution in the atmosphere. When the rainfall occurs, it almost always causes harm to the environment. 2. Acid rain is caused by the release of certain compounds into the air, including sulfur dioxide and nitrogen oxides. These compounds mix and react with chemicals such as oxygen and water and form acid rain. 3. Acid rain can harm the environment by acidifying lakes and streams, which greatly affects the water life. It also causes damaged to tall trees and soil. 4. Acid rain makes buildings affected decay quicker in their materials and paints. 5. Acid rain has the most effect in areas where sulfur dioxide and nitrogen oxides are present in the atmosphere. Some of these areas with high pollution are China, Europe and Russia. 6. In order to reduce acid rain, environmental programs are encouraging more efficient functioning in coal-burning power plants, more uses of alternative energy and the use of more environmentally-conscious vehicles. 7. www.epa.gov

OZONE DEPLETION
1. Ozone is a toxic gas with powerful oxidizing properties.
2. Ozone is composed by oxygen affected by electricity or ultraviolet light. This created the chemical compound of O3 3. Ozone is present in the stratosphere of the Earth.
4. In the atmosphere, ozone works to absorb UV-B from the Sun. 5. Ozone depletion can cause harm to the health of humans, causing skin conditions and disease. Also, the increased level of UV-B resulting from ozone depletion harms many major world crops, as well as certain marine and domestic animal species. 6. Certain stratospheric phenomena and springtime polar tropospheric events can result in further depletion of the ozone layer. 7. When ozone becomes in contact with photocatalysts it is broken down and converts back to oxygen. 8. CFCs are man-made Chlorofluorocarbons that cause ozone depletion. They are found in common items...
