No smoking on school campus
As we all know,school campus is a public place where students study.So it should be banned smoking on school campus.Nearly every school has banned smoking at school.This is a good idea though it takes away some of our freedom.
As we know,smoking is harmful not only to our health but also to the environment.Smoking can lead to many diseases,such as lung cancer.Smoking affects non-smokers more than it does smokers.Ratio of passive smokers getting ill is higher than that of smokers.So,many nonsmokers are against smoking.
In public places,the harm of smoking is greater.This is connected with another effect of smoking.That is,smoking pollutes environment by giving much poisonous vapour off into the air.
Therefore,it is very necessary and important to us that smoking should be banned.It is a measure to protect our health and environment.So many people,especially nonsmokers are for the policy.
Some students in colleges say that it take away some of our freedom.I think it is a one-sided view.If one wants to smoke,he may smoke in private,not in the public places.In fact,smokers still have the freedom of smoking.
As far as middle school students and primary schools are concerned,pupils and middle school students are not mature.Smoking will do extra harm to them.So it must be a rule that smoking be banned.
I think,smokers had better give up smoking,not only in private places,but also in the public places,everywhere.It will be beneficial to all of us.
