Plastic bag was once called as the most useful invention in the 20th century and it was disposable in our country in the past few years.
However, in recent years, as the excessive use of plastic bag has brought a great pollution to our environment, our country has established and carried out a series of relevant regulations to limit the use of it. Since then most supermarkets have not provided free plastic bags when we are shopping.
In my opinion, limiting the use of disposable plastic bags is a significant and meaningful measure or policy to decrease environmental pollution as well as save social resources. And it also illustrates that our nation have realized the importance of environmental protection. Hence, it is really necessary and important to keep carrying out this measure or policy so that our nation and even the whole world can achieve sustainable development.
