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.
塑料袋曾被称为20世纪最有用的发明，近几年来在我国是一次性的。
然而，近年来，由于塑料袋的过度使用给我国环境带来了巨大的污染，我国制定并实施了一系列限制塑料袋使用的相关法规。从那时起，大多数超市在我们购物时都没有提供免费的塑料袋。
在我看来，限制一次性塑料袋的使用是减少环境污染和节约社会资源的一项重要而有意义的措施或政策。同时也说明了我国已经认识到环境保护的重要性。因此，继续实施这一措施或政策，使我国乃至全世界都能实现可持续发展，是十分必要和重要的。
