As we know,smoking is harmful not only to our health but also to the environment.And we should not take blind eyes when it comes to cars tail gas pollution.By no means ought we to ignore.
Therefore,it is very necessary and important to us that the government ban smoking .It is a measure to protect our health and environment.So many people,especially nonsmokers,are for the policy.Besides,the elimination of air pollution needs the collective efforts from the government,the public and the environmentalists.the increasing number of car should also be
controlled.
In summary,forced with the serious situation of air pollution,all of us should take efforts to handle it.I firmly believe that we are heading for environment disaster unless we fundamentally
change the way we live.
