Think what would happen in the nature of your area, if it disappeared altogether water .  Where there is water , there is no life.  If a houseplant is not watered, it withered . Grass, trees, animals can not live without water.And a person dies without water , too . Man needs water not only for drinking and cooking. Water we wash ourselves , it washes clothes . It is necessary to maintain the cleanliness of homes, public buildings , on the streets.  Man moves on the water in boats and steamers , transports products and machines , alloy timber .  Water moves the machines that produce the electric current . She needs factories and railways.A lot of water in nature. It is everywhere in the oceans, seas, lakes and rivers on the land surface , in the bowels of the earth, in the air above the ground.  Think about how you use water in your life, if you spend a lot of it, what about some of the water goes to quenching thirst , and which - for various household needs .
