Humans are wasting things all the time. Wherever we go, we can see paper, bottles and cans being thrown away; Food is wasted just because it tastes bad; Clothes are discarded simply because they are out of date. Not only things and money are wasted, but also natural resources are abused. Trees are cut down only for fuel; Wild animals are killed only for meat and fur; Oil and coal are mined in a poor way.

The worst example of human waste is wasting time. Many people tend to spend their time on worthless things, such as loitering in the street, chatting in the office and sleeping too much during the day. As we all know, time is very precious to us, because it is gone forever. A waste of time is a waste of life.

It's time to call for an end to waste. On the one hand, we must save and make full use of natural resources; Otherwise, mankind will face the shortage of natural resources and suffer from the pollution caused by waste. On the other hand, we must cherish time. Only by spending our time studying and working for the people can we not regret our life.
