Save water at home
We are paying more attention on many environmental problems we made before,one of them is the water emergence.Long time ago,we never noticed that we are in a situation that the water on the earth is less than before,and the consequence is continuing.
Until recently,we have started to acknowledge that we should make the bigger efforts to save water.Therefore,so save water from every single person is important.That is why we should save water at home.If every one of us saves water at home,then the water saved together would be a huge amout.And I have some suggestions following:we could cycle the water we just used them to wash clothes to water the plants or to rush the toilet; when we wash our hands,we could turn the tap off for the moment we put soap on our hands etc.
So if we want to save water sincerely,we could save it at home.
