Mankind i wating thing every'where and everyday. Wherever we go, we can ee that paper, bottle and can are thrown away; food i wated jut becaue of poor tate; clothe are dicarded imply due to their old fahion. Not only thing and money are wated, but natural reource are abued a well. Tree are cut down merely for fuel; wild animal are killed imply for meat and fur; oil and coal are exploited in a bad way.
The wort example of man' wate i the wate of time. Many people tend to pend their time on worthle thing, uch a wandering about in the treet, goiping in the office, leeping too much during the day. A we know, time i very preciou to u ince it pae by and never return. The wate of time amount to the wate of life.
It i time to call for an end to the wate. On one hand, we mut ave on natural reource and make full ue of them; otherwie human being will be faced with the hortage of natural reource and uffer from the pollution caued by wate. On the other hand, we mut trea ure our time. Only with our time devoted to the tudy and the work for the people, will we never regret the life we have had.
