China has decided to stop the use of free plastic bags. Supermarkets, shops and outlets (经销店) in China can't offer plastic bags any more. Every year, people use too many plastic bags. They throw them here and there after they have used them. The government has done its best to deal with them but failed. While we offer quick service (服务) to customers, the plastic bags pollute water, earth and air, and they waste the oil. The government asks people to go back to carry cloth bags and use baskets when they go to buy something. The cloth bags and the baskets can be used again and again. Many months have passed. The environment has been improved a lot.
