Environmental pollution is one of the most serious problems faced by humanity today. Air, water and soil-all harmed by pollution are necessary to the survival of all living things. Badly polluted air can cause illness, and even death. Polluted water kills fish and other marine life. Pollution of soil reduces the amount of land available for growing food. Environmental pollution brings ugliness to our naturally beautiful world.
Everyone wants to reduce pollution. But the pollution problem is as complicated as it is serious. It is complicated because much pollution is caused by things that benefit people. For example, exhaust from automobile causes a large percentage of all air pollution. But the automobile provides transportation for millions of people. Factories discharge much of the material that pollutes air and water, but factories provide jobs for people. Too much fertilizer or pesticide can ruin soil, but fertilizers and pesticides are important aids to the growing of crops.
Thus, to end or greatly reduce pollution immediately, people would have to stop using many things that benefit them Most people do not want to do that, of course. But pollution can be gradually reduced in several ways. Scientists and engineers can work to find ways to lessen the amount of pollution that such things as automobiles and factories cause.
Governments can pass and enforce laws that require businesses and individuals to stop or cut
