What Can Do for the Environment 为题写一篇“低碳生活”的演讲稿

内容包含：1、在购物时用布袋子替代塑料袋2、尽可能地再利用使用过的课本3、离开教室应关灯4、最好走路或骑自行车上学5、简述理由：保护环境，节约能源等

Hello，everyone.I'mZhangLi.It's nice to speak about what we can do for the environment，and I think each of us can do a little bit to help with this problem.

What can we do for the environment?There are many ways.We should use cloth bags when shopping instead of using plastic bags all the time.We should also reuse the books as possible as we can.What's more，we should turn off the lights when we leave the

classroom.And we'd better walk to school or ride our bikes instead of driving cars.All in all，each one of us is responsible to protect the environment，and we should save the energy in our daily lives. In fact，If everyone does something for the environment，I believe the earth will be a better place.Thank yon for yonr listening!

Lower carbon life

Now more and more people get to know it's important to protect our living environment. As a student，it's my duty to do something for the earth.

From now on，I'll go to school by bike or on foot instead of in a car.I'll use fewer plastic bags【少用塑料袋】to reduce white pollution【减少白色污染】.In order to save energy，I'll plant more trees so that the air will be fresher.I'll take less lift and reuse water【循环用水】.At last l will use second-hand books【使用二手书】，so we don't need to cut down more trees. If everyone takes action，our enivronment will be better and better.Our world will be more beautiful.

One possible version：

The diagram shows the weather changes in the global climate. It tells us that the global average temperature has increased by 0.8℃ from 17℃ in 1951 to 17.8℃ in 2001. thus, we can come to a conclusion that our earth is getting warmer and warmer.

As far as we know, the major reason for global warming is due to human activities. Firstly, the use of fossil fuels by industry releases greenhouse gases. Moreover, cutting down forests means that less carbon dioxide can be changed back into oxygen. As a consequence of global warming, the sea level is rising. And people are suffering more extreme weather of global warming, the sea level is rising. And people are suffering more extreme weather. The increase in temperature is also causing much damage to the balance of nature.

It’s high time that we should take measures to protect our earth. Not only can we control the releasing of carbon dioxide, but also we can be encouraged to use new energy, such as solar energy. In a word, only in this way can we make our earth a better place for our human beings.
