suggestion letter 2 Dear Sir or Madam, As an undergraduate of local university,I'd like to put forward some suggestions concerning the "white pollution"problem for your consideration. My first suggestion is,the awareness of environmental protection of people should be enhanced,which plays an important role in solving this trouble.In the second place,markets must ban customers from using plastic bags when shopping,and tell them bring cloth bags next time by themselves. I hope you will take my suggestions into account.Thank you. Yours faithfully, Li Ming
