Mankind is wasting things every'where and everyday. Wherever we go, we can see that paper, bottles and cans are thrown away; food is wasted just because of poor taste; clothes are discarded simply due to their old fashion. Not only things and money are wasted, but natural resources are abused as well. Trees are cut down merely for fuel; wild animals are killed simply for meat and fur; oil and coal are exploited in a bad way.

The worst example of man's waste is the waste of time. Many people tend to spend their time on worthless things, such as wandering about in the street, gossiping in the office, sleeping too much during the day. As we know, time is very precious to us since it passes by and never returns. The waste of time amounts to the waste of life.

It is time to call for an end to the waste. On one hand, we must save on natural resources and make full use of them; otherwise human beings will be faced with the shortage of natural resources and suffer from the pollution caused by waste. On the other hand, we must trea sure our time. Only with our time devoted to the study and the work for the people, will we never regret the life we have had.
