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 o
power. According to Professor Marvin Burnharm of the New England Institute of
Technology, we have to start conserving coal, oil and gas before it is too late; and nuclea
power is the only alternative. However, many people do not approve of using nuclear
power because it's very dangerous. What would happen if there was a serious nuclear
accident? Radioactivity causes cancer and may badly affect the future generations.
The most effective thing is that we should use natural resources as economically as
possible.
