高一英语作文演讲稿关于环境

　　If the human race never stops, then the vengeance of nature will not cease until the end of the human race. Because only human beings can stop what they do. Is it only when the last tree in the world is cut down and the world's last animal is hunted?

　　The absence of loud human slaughter and deforestation is nothing compared to the horror of natural vengeance. In the heart of human tears of despair and they vaguely recall game in the forest, when he was a child in the forest and animal close contact, loggers to logging hunters to hunt animals he had stepped in. In tears of regret and despair, the earthquake stopped suddenly, and the flood slowly faded away, leaving only the ruins of man.

　　We live in the world every day. We eat food, drink water, wear clothes, watch TV, use computers and so on. We are producing waste every moment.

　　Generally speaking, there are four sorts of waste. They are material waste, organic waste, inorganic waste and poisonous & harmful waste. Now, we are going to talk about each sort of waste one by one.

　　Material waste: it means the waste of substance or things from which something else can be made. For example, people throw away the used metal products and buy a new one, so the old metal waste accumulates. At last, they become waste. For example, when people finish reading newspaper, the paper will become waste. When the glass is broken, it also becomes waste. Nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. Once it is broken, it becomes waste. The rate of using plastics is increasing day by day. People use plastic bags because they are convenient. When they get home, they throw the plastics way, paying no attention to the environment. The more convenience plastics brings to us, the more plastic waste is produced. This is called “white pollution” as most plastics are white. Some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes. It’s true that rubber plays an important role in our life. However, it also brings us some trouble when it has been used for a long time and becomes old. The old tyres become waste because it can’t break down by nature. This is really a big problem.

　　We have only one earth. But now,the environment becomes worse and worse.

　　As you know,there's no enough clean water for people. So many of them lose their lives because of water. In a lot of countries, people have to cut trees for living. So there's nothing to keep water from running away. Also we have polluted the land, the river and the air. So we have to face more and more floods and droughts .

　　It's time that we must do something useful to protect our environment. We can plant trees and take good care of them. We can save the water and ask our parents to do so. We can't throw any litter onto the ground and we should collect them for recycling.

　　If we take good care of our earth today,it will be more beautiful tomorrow.
