　　Disposable Plastic Bags

　　Nowadays we may find ourselves surrounded by a sea of disposable plastic bags. And recently the problems of using disposable plastic bags have been brought into people’s focus.

　　First of all, the use of disposable plastic bags causes irreversible harm to our environment. As these bags are not biodegradable, they are blocking the drainage system and causing water pollution.

　　What’s more, customers using disposable plastic bags may think that they are of great convenience. But what they don’t quite realize is that there will be remarkable negative impact on our health. And sometimes careless disposal of these bags may even poison some innocent animals.

　　In view of the severity of this issue, effective measures have been taken in our country. There has been a strict limit on the using of disposable plastic bags in supermarkets, which not only enhances people’s awareness on environmental protection but also cuts down the cost of the running of supermarkets.
