Dear David ,

      I’m glad that you’ve noticed our efforts directed towards environmental protection. Thanks your concern.

      Although too much use of plastic bags has caused serious white pollution, our government encouraged us to use environmentally–friendly shopping bags. These bags are made of a variety of material that can be easily treated when they become a rubbish. Besides, they can be reused. Realized the advantages of such bags, more and more people have started using it.

     I believe that the widely use of these shopping bags can improve their environment. This is one of the many steps we take to make our country an even clean place.

Sincerely yours,

Li Hua
