It may be in the air, in the earth, in the body of living things, even in the driest place. 71 percent of the earth's surface is covered with water .But the water is polluted and wasted seriously. For example, there are many factories pouring waste water into the rivers, a lot of people put litter into the rivers,too.So, it's time for us to do something useful to save water. We should try our best to save every drop of water .
