Dear Sir,
Nowadays,there exists an increasingly serious environmental problem. White pollution has e mon concern of the public.   According to a survey,in some areas the ban on the use of plastic bags are not very essful,so white pollution continues
In my humble opinion,you would be wise to take the following actions. The first action is that,your newspaper would strengthen to report the problem about the bad of plastic bags. The second action is that ,your newspaper should persuade people not to use plastic bags. The last action is that your newspaper should allow the Government to formulate some policies to ban on the use of plastic bags.
I hope you will find these proposals useful,and I would be ready to discuss this matter with you to further details.
Yours sincerely
