不要浪费水(Don't Waste Water)

a man is washing his clothes ,regardless of the notice above as we see ,water is the source of life. but there is very limited available water resources 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.
