As we know, water is very important to man, we cant live without water. The amount of water which is suitable to drink is less and less. But some people dont care about it. They waste a lot of water in their daily life. Even worse, they pour dirty water into rivers. They throw rubbish into rivers, too. Many rivers and lakes are seriously polluted. Something must be done to stop the pollution. And I think its a great shame to waste while millions are in great need of water. I think what we can do is that we have to save every drop of water as possible as we can. For example, we must turn off the tap immediately after we use it. We can use a basin to wash our hands and faces. Its also a good idea to encourage my friends and family members to join me! Only in this way can we live happily. If we dont save water, the last drop of water will be a tear-drop of us. I believe if everyone makes a little effort, we can make a big difference.
