Nowadays, China has made laws to stop the use of free plastic bags. When we go shopping, supermarkets,

shops and outlets no longer offer us free plastic bags. This is a great action to reduce pollution and protect the

environment. However, some people find it unnecessary. They think it may cause trouble if they go shopping

with a cloth bag or basket. In my opinion, the only earth is our home. It's our duty to protect and look after it

so that our children and grandchildren can still enjoy a beautiful world.
