From June1, 2008, shops and supermarkets are forbidden from offering free plastic bags to customers, according to a new law. A nation-wide campaign against plastic bags has been launched.

Nowadays, Chinese people use up to three billion plastic bags a day. While being very convenient to shoppers, plastic bags also cause serious white pollution” and waste resources.

Though the ban may cause some inconvenience to shoppers, it can help reduce the use of plastic bags when people have to pay for them. Besides, the ban, in away, can promote public awareness of environmental protection.

So I think it necessary to forbid shops and supermarkets from offering free plastic bags. When shopping, we can use cloth bags or baskets instead of plastic bags as we used to.
