All the people
There are still many problems of recent years. The pollution of air, water and soil(土壤)is considered to be one of the most serious problems . The polluted air does great harm（危害） to people’s health. The polluted water causes illness and death. To protect the environment, Chinese government has taken many steps to stop pollution. So we will develop and improve a new management system（管理系统） to save the city environment. The government must pay more attention to the environmental pollution . First, it should let all the people fully realize the importance of it by education. Second, much more efforts(努力) will be made to put the policy(政策) into practice, because more people means more pollution. Finally, those who destroy the environment will be seriously punished(惩罚). We should let them know that destroying environment means destroying human beings(人类) themselves. The government encourages people to do something to protect the environment .
