We need water to drink,take a shower or bath, water plants and so on. So without water, life can’t go on. Most part of the Earth is coverd by oceans. But people are always wasting（浪费；waste）water. They often leave the tap on when they brush their teeth. We should try our best to save water. For example, we can take a shower instead of a bath. That can save a lot of water.Protecking Our Environment The environment is everything around us, such as plants, animals, air, water and land. And environment is different in different parts of the world. The earth is the home of all plants, animals, and man. But man has polluted both air and water and killed animals for food. Many animals are dying out. Now many people are afraid that。
