That's why it's important to use water wisely

Plants, animals and people need water to live
Human beings need about 2 quarts a day to digest food, transport wastes, keep cells alive, make blood and control body temperature. We get some of this water by drinking. Some comes from food -- an apple, for example, is about 3/4 water, and a ripe tomato is mostly water.

Nearly 2/3 of your body is water! Enter your weight (in pounds): This is how many 8-oz glasses it would take to equal the water in you!
People also use water for: cooking bathing cleaning flushing toilets growing food making paper, steel and other products making electricity having fun In too many cases, precious water is wasted in the process.
