Curb pollution before it's too late

Air pollution has many disastrous effects on society and thus needs to be curbed. Governments, scientists and environmentalists across the world are using or testing a variety of methods aimed at reducing pollution.

There are two main types of pollution control. The first is input control, which involves preventing a problem, or at least limiting the effects the process will have on the atmosphere and people. There are five major input control methods in air pollution management. People could try to restrict population growth, use less energy, improve energy efficiency, reduce waste and/or shift to non-polluting renewable forms of energy production. Also, automobile emissions can be reduced with highly beneficial results.
