Protection of Environment
　　There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. The polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation（总称  植物，草木） had been greatly reduced with the rapid growth of modern cities.
　　To protect the environment, governments of many countries have done a lot. Legislative （立法的）steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.
In my opinion, to protect the environment, the government must take even more concrete measures. First, it should make people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying the environment means destroying mankind themselves.
