Contaminating the Environment Humans are able to control nature unlike any other creature here on earth. We are the smartest of all the animals on this planet. This is why we are able to control most of the good or bad effects that happen here on earth. However, we do not always do what is best for the environment. Every year people and animals die from us polluting the earth. Chemicals are becoming one of the main problems with controlling the environment. Humans’ spray poisons on the land we live on and expect that nothing wrong will happen. These poisons eventually end up in our water we drink or shower in. There are many chemicals that cause harm to our environment. “Strontium 90, released through nuclear explosions into the air comes to earth in rain or drifts down as fallout and embeds itself in the soil where it enters into the grass or corn and eventually finds its way into the bones of human beings to remain there until death.” (Carson 513) Every year there are new pr!
oducts that threaten the environment. These products or chemicals can float into the air and are becoming a major source of pollution. Some chemicals we have created are depleting the ozone layer. Humans use dangerous materials to contaminate the air
educe the amount of evaporation of the ocean water and would then cause the earth to have less rainfall. When there is less rainfall there aren’t 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
