How to save our world?Now the environment is worse and worse. The environmental problems influence our work, life and study. And our work, life and study also make the pollution worse and worse. Much water is polluted and the air pollution is more and more serious. People cut down many trees in order to build houses or factories. You can see white rubbish every where. So what should we do to stop pollution? First we should stop people polluting rivers and lakes. Second we should plant more tress in order to make the air cleaner and clearer. Third we should turn off lights when we leave the house. Finally everyone should pay more attention to saving water and energy. In this way, the environment will be better and better.
