As it known to all,living things cannot live without water.There has been water since billions of years ago.But today more and more water is polluted,and our enviroment is in danger.We should protect water trying our best.Reuse water is a important way to solve this problem.If all the water were polluted,people cannot live ourselves.For the reason we must protect seas ,rivers and the underground water,otherwise the last drop of water will be a teardrop!
