Pollution

2013-11-13 来源: 类别: 更多范文

Pollution Pollution is any substance or form of energy in sufficient concentration to harm living things or the environment. Pollution is created by individuals, communities and by industries that collect and dispose of pollutants improperly. Four types of pollutants are air, water, ground and energy. Air pollution can be caused by cigarette smoke, carbon dioxide, automobile exhaust, combustion products from heating, power plants, radioactive particles, improper solid waste disposal, fires and chlorofluorocarbons (CFC’s). Polluting the environment is destroying the ozone. The ozone protects us from harmful ultra violet rays and radiation that kills us. Too much air pollution on earth is slowing down the ozone’s ability to re-build itself. A solution to minimizing air pollution is to ban CFC’s from being made or used and finding other chemicals to replace CFC’s. If an air conditioner breaks, the CFC’s have to be taken out very carefully and either stored or recycled so they don’t leak out into the air. People should stop smoking. Smoking is bad for your health and the smoke pollutes the air. So even if you make a healthy choice by not smoking, u will still be harmed by second hand smoke.
