China has decided to take actions to stop the use of free plastic bags. Supermarkets and shops in China aren’t allowed to offer free plastic bags.
Every year, people use too many plastic bags and fail to deal with them in a right way. While we offer quick and useful service to customers, the plastic bags cause serious pollution as well. For example, people will throw away plastic bags after they use them. The waste plastic bags may fly with the wind and make the environment ugly. Worse still, animals may eat them by mistake and die. Besides, It’s difficult to find new land to put the waste plastic bags in, so plastic bags are burned. The burning plastic bags give out harmful gas.
So the government encourages people to go back to carry cloth bags and use baskets for their shopping things.
