A man is washing his clothes, regardless of the notice above "Save the Water Please."
As we see ,water is the source of life. But there is a very limited available water resource in our world. So we shouldn't waste it. Of course, we have to use it to drink, cook, wash, clean and etc. But we must remember not to use it extravagantly. If we didn't stop such wasteful habits, we would cut off the development of the world and the human life.
