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

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 saving coal, oil and gas before it is too late; and
solar power is the only alternative.

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