Plastics are man-made materials with new properties. They are anywhere in our daily lives. They are very light but they can hold heavy things. That’s why they’re so popular all around the world.

Plastics have found their widest applications. They can be used for almost everything from food coverings to automobiles¹ bodies. Thousands of different products are now made entirely² or partially³ from plastics. Of course more and more plastics will be made in the future.

However, because the plastics are not rusting⁴, they have negative effects on the global environment. The plastics bags are not easily to break down. If you’re burning them, they gas will pollute the environment. If you throw them into the river, the fish will die because they’re contain toxic⁵. If you bury them, the land will not grow any crops. Most of the plastics are white, thus people call it “white pollution”.

In order to protect the environment, we should not use plastics if we could. We should use some cloths bags instead. Only in this way, we can have a good environment.

塑料袋是人们用新型材料制作的物品。在日常生活中，他们随处可见。塑料袋质地轻盈，却能承重。这就是为什么它们在全球都如此受欢迎的原因。

塑料袋有着广泛的用途。从食品包装到汽车部件，塑料都可以起到自己的作用。成千上万的物体完全或是部分由塑料构成。当然，未来越来越多的塑料制品会应用到生活中去。

然而，因为塑料袋不能分解，这给全球环境造成了很大的污染。它们很难分解。如果你烧它们，它们排放的气体会污染环境，如果你把它们丢进河流，鱼会因为塑料分解的有毒物质而死亡。如果把它们埋进土里，就会导致庄稼无法存活。因为大多数的塑料袋是白色的，所以又称为“白色污染”。

为了保护环境，我们应该尽量不使用垃圾袋。我们应该用布袋来代替垃圾袋。只有这样，我们才能有个好的环境。
