human beings perish. The affected land becomesparched and dry. Nothing grows.
As long as there is life on this planet, water will be here.Without it, life as we know it is impossible. Thus it isimportant for us to know how precious water is. We
ought not to waste it or pollute it by any means. Water isjust too precious.
