SAVING ENERGY
Many people still believe that natural resources will never be used up. Actual, the world’s energy resources are limited. Nobody know exactly how much fuel is left. However, we also should use them economically and try finding out alternative sources of power. According for Professor Marvin Burnham of the New England Institute of Technology, we have to start conserving coal, oil and gas before it is very late; and nuclear power is the only alternative.

Radioactivity causes cancer and may bad affect the future generations. The most effective thing is that we should use natural resources as economically as possible.
