June 8 Dear David, Thank you for your concerning that Chinese are encouraged to use the environment-friendly shopping bags instead of the plastic ones.Actually in the past ten years,Chinese people have used too much plastic shopping bags.Though convenient it is,it also does great harm to our healths as well as our farm lands.So in order to deal with this great white pollution,our government encourages us to use the enviornment-friendly shopping bag when going shopping.As a member of our earth,at the point of my view,we everyone should try our best to reduce the pollution and protect our environment. Yours, Li Hua
