　　c. 我的看法

　　When asked about one of the biggest problems today, many people say that an energy crisis is approaching and is threatening mankind's survival. They are afraid that the world is likely to run out of oil and metals and to run short of food in the near future.

　　To this problem, most countries respond with the demand for more rigid conservation of our natural resources. Indeed, this is urgently needed, for the present waste of energy in industrial and personal consumption is so serious that it has become habitual and traditional. If the natural resources are used economically, we can certainly slow down the present drain on the limited energy supply. However, conservation alone is not the answer. It is obvious that even if we can save much energy, we can only delay the energy crisis, but cannot solve the problem completely. However abundant certain natural resources may be, they cannot reproduce themselves and are bound to be used up ultimately. So in the long run, we must develop new sources of energy instead of merely conserving the known, limited supplies.

　　Man is highly adaptable and creative, and since he is able to tap such resources as oil and metal, why can't he develop and harness solar energy, nuclear energy and other unknown energy resources?
