Water is very important to us,we can't live without r pollution is a serious problem,it causes our drinking water becomes less .I think we should protect the water and reuse them,such as don't pour the waste water into the river,remember not to spit into the river and don't throw rubbish into the river and so shoule save water . If we do these well,the water will be we don't save water,the last drop of water will be our tear.I really hope the government can do something useful to protect the water.
