In most parts of the world, many students help their schools make less pollution. They join" environment club". In an environment club, people work together to make our environment clean.
Here are some things students often do:
No-garbage (无垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will select the class that makes the least garbage and commend (表扬) it to the whole school！
No car day. On a no-car day, nobody comes to school in a car, neither the students nor the teachers！Cars give pollution to our air, so remember:
Walk, jump, bike or run.
Use your legs！It's lots of fun！
Turn off the water！Do you know that toilets can waste twenty to forty tons of water an hour? In a year, that would fill a small river！In environment clubs, students mend those broken toilets.
We love our environment. Let's work together to make it clean.
