For one thing , environment plays a decisive role in providing man with everything necessary to survive such as air, water, food , and so on. For another, man has also done everything he can to protect environment. ??However, environment has been damaged seriously at present. There are three examples for this. First, the air has been polluted to such a degree that in some places there is no clear sky most of a year ,especially in winter. Second, water has also been polluted so seriously that famine and drought frequently occur in some countries. Third, food has been polluted too. As a result , some endemic diseases are prevalent in certain regions. ?? Some effective measures must be taken to prevent the situation from becoming worse. On the one hand, government of all levels should pass specific laws to stop the damage to the environment. On the other hand, we should pay much attention to increase the public consciousness of the importance of environmental protection. In this way , we can hope to live in a beautiful and clean world .
