h time reduced sunlight could reduce the amount of evaporation of the ocean water and would then cause the earth to have less rainfall. When there is less rainfall there arent as many plants being grown. Having fewer plants will cause more animals to starve to death. If plant and animal life is destroyed then we will eventually perish too. Another threat is posed by acid rain, a type of air pollution. The burning of fossil fuels causes acid rain. Once these fossil fuels are burned they are released into the air. Once in the air, some acid-forming materials-large particulates-from power plants, industries, and mobile sources fall to the earth just a few miles away or within 18 to 30 miles.(Gay 27) When this occurs these acid materials end up in our water or on the land we live on. Another problem we face is water pollution. Water is our most valuable resource. It is used for a variety of uses. Factories, sewage treatment plants, and oil tankers cause water pollution. If an oil tanker has a leak it covers the ocean with oil. This oil ends up on our beaches and kills animal life and makes our beaches not safe to go to. Farmers runoff water containing pesticides and fertilizers from acres of agricultural land are a major source of water pollution. They spray poisons on crops to prevent insects from infesting the fruit or vegetables. These poisons seep into the ground and then cause water pollution. This pollution is much more difficult to control. The runoff water from the farms accounts for a majority of the contaminants in streams and lakes. For example, just one liter of insecticide killed over 1,000 fish in the River Glaven in Norfolk. During the 1950s, otters in many parts of the country were nearly wiped out by the accumulation of pesticides in our rivers. (www.wildlifetrust) With almost 80 percent of the planet covered by oceans or lakes, people have thought that these bodies of water could serve as a limitless...
