No matter where we go, we can see a lot of people cutting down trees, polluting water and air. There is no doubt that it is important for us to develop the habit of protecting the environment. What’s my low-carbon life like in my everyday life? First of all, I walk to school every day. Walking is not only good for the environment, but also for our health. Besides, I save energy by turning off the electrical in time, such as lights and fans, when leaving the classroom. Last but not least, I always make full use of paper and never waste water. Protecting the environment is not only the business of the government, but also the responsibility of each of us. Even a small effort can make a great difference, so let’s take actions from now on to live a low-carbon life. 7 Work in pairs.
