To protect the environment, China has put a ban(禁令) on thin plastic bag (plastic bag thinner than 0.025 mm). From June 1,2008, China stopped the production, sale and use of these plastic bags to the public.

Plastic bags can cause “white pollution”, because they can take 400-1,000 years to break down. They pollute the soil(土壤) and water. Plastic bags also cause a serious danger to animals. Animals often mistake plastic bags for food. Thousands of them die each year after eating plastic bags.

So what kind of bags will be the best to use when we are shopping? Recently some students made their own shopping bags. Most students used old clothes to make their bags. They painted pictures like the Olympic rings on them. But Li Mei had a more traditional way to make her hag. She weaved(编织) a bamboo(竹子) basket. It was not an easy job. With her grandfather’s help, Li Mei spent the whole afternoon making it.

What can we do? Refuse plastic bags and persuade(说服) people to use environmentally friendly(对环境无害的) shopping bags instead of plastic ones. Try to recycle the ones we have.
