As we know, water is very important to man, we can’t live without water. The amount of water which is suitable to drink is less and less. But some people don’t 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 it’s 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. It’s also a good idea to encourage my friends and family members to join me! Only in this way can we live happily. If we don’t 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。
As humanwe should know it is so important that the water for us.about 70% composition of a person's body is water.and we can leave off food to live for long time(at least 7 days) but not more than 72 hours we will die if we leave the water.
the reality now days is the resources of water lacked day by day .this require us must save in useing water.how to do it? in public bathroomwe shouldn't keep the clean water running without stop in familywe should save water toothe water after washing fruit and vegetables can used in cleanning floor.and the last time of water by washing face also can be used in wash toiletand so on.....
