Many people still believe that natural resources will never be used up. Actually, the world’s energy resources are limited.

Nobody knows exactly how much fuel is left. However, we also should use them economically and try to find out alternative

sources of power. According to Professor Marvin Burnham of the New England Institute of Technology, we have to start conserving

coal, oil and gas before it is too late; and nuclear power is the only alternative. However, many people do not approve of using

nuclear power because it is very dangerous.

The most effective thing is that we should use natural resources as economical as possible.
