　　Limiting the Use of Disposable Plastic Bags

　　1) 一次性塑料袋曾廣為使用

　　2) 由此帶來的問題

　　3) 限制使用一次性塑料袋的意義

　　A serious problem our country has been faced with is the widespread use of disposable plastic bags in the past. These bags could be seen everywhere, from restaurants to department stores, and from university campuses to school children’s playgrounds.

　　It goes without saying that these bags have brought about a wide variety of problems. In the first place, they pollute our environment because, as everyone knows, it takes the bags hundreds of years to disintegrate. Meanwhile, they emit dangerous gases when burned. In the second place, it is a huge waste if we do not use these bags again. This goes against the grains of “sustainable development”. Last but not least, these bags make our cities dirty, which is the reason why they are called “white pollution”.
