one possible version：
Plastic bags are very popular in our daily life, especially they are widely used in free markets, supermarkets or departments.
As we all know, plastic bags are one of the major pollutants and we can see littered plastic bags thrown everywhere. Because plastic bags are not so degradable, it’s easy for them to pollute our environment and even many wild or sea animals may be choked to death by them. What’s worse, “white pollution” does harm to the image of China.
So our government should make law to forbid the use of plastic bags in department stores and supermarkets. Meanwhile, people should be e
ncouraged to replace them with paper bags or cloth bags.
