The following are some small things that may lead to big improvement of the environment.Firstly wash your clothes by hand instead of using washing machines. Secondly don’t take elevators unless it is necessary. Using stairs does good to both your health and the environment. Thirdly remember to bring your own shopping bags when you go to the supermarket. Lastly go to school on foot or by bicycle.we should turn off the tap after we use the running water. If we can make a small change in our way of life, we can make a big difference to the earth!du。

Buses produce carbon too.Let’s take action and be low-carbon people!。
