For many years, we have been told that China is rich in various natural resources so many people take it for granted that they are inexhaustible. People have not considered that one day some of these natural resources will be used up and that we will then be faced with energy crisis.

As a matter of fact, many of the natural resources can't be replaced once used up such as the coal mines or oil fuels, etc. Energy crisis will threaten our existence because of our excessive exploitation and because of the growing population.

Considering the above the government should try to take some action to protect the natural resources and people should be educated not to waste them.

多年以来，我们一直被告知中国是一个资源富饶的国家，于是许多人想当然地认为这些资源是用之不竭的，他们从未想过有一天，有些资源会被用之殆尽，而我们也将面临着能源危机。

实际上，许多自然资源一旦被用尽则无法找到替代物，比如煤矿、油田等等。由于我们的过度开采和人口的不断增长，能源危机将威胁着我们的生存。

综上所述，政府应该采取一定的措施去保护自然资源，并且还要教育人民不要浪费它们。
