Model Test Five White Pollution

Outline: 1. 白色污染的含義及其產(chǎn)生的原因2. 列舉白色污染所帶來的危害 3. 我們應(yīng)該怎么辦

Good morning, honored professors and fellow students. It’s my pleasure to stand here to give the speech. The topic of my speech is White Pollution.

White pollution refers to plastic pollutions, which is caused by the abandoned plastic products. Plastic products release toxic gas into the air, and also will pollute the water. Those plastic products which cannot be decomposed will cover large areas of ground for a long time, for instance, 100 to 200 years.

To reduce white pollution, we must use plastic products, especially plastic bags as few as possible. We can use baskets and cloth bags to take the place of plastic bags. Also, we can reuse plastic products, for example, we can use the plastic bags from the supermarkets for the rubbish, rather than throw these bags away immediately.

White pollution is just around us, and the responsibility to reduce white pollution is rightly on our own shoulders. Let’s take actions.

That’s all, thank you.
