Water resources on earth are limited. But maybe some people dont know, because they waste water casually. Some people turn on the tap and forget to turn it off so that the water keeps running; others forget to turn it off because they are doing something else. This little thing is a waste of water caused by carelessness, but it is not necessary.

Here, I suggest that we must close the tap, turn off the water in time when we leave, recycle the water, such as: floor water can be used to flush toilets, rice water can be used to wash dishes and so on.

Lets start now!
