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’s too late; and nuclear 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 were 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.
1. We can use natural resources as much as possible. 
2. The alternative sources of power are very important for future use. 
3. We can easily find kinds of alternative sources of power in nature.
