帮忙写英语作文~假设你是李华,戴维是你的美国朋友,他对中国用环保购物带感兴趣,来信询此事,请回信

Hey David,
I am Li. I have heard that you are interested in the reason why China promotes environmentally friendly shopping bags. Let me explain it to you.
Since 2 years ago,the * tried to limit the usage of plastic bags through charging at least 10 cents for each of them. This policy effectively reduced the number of plastic bags being wasted and encouraged people to use environmentally friendly shopping bags. It directly helps the environment. I believe you will be impressed by this news.
Your friend,
Hua Li
