In an environment club, students work together to reduce pollution and protect the environment.The following is a list of their activities and advice. ●No-garbage lunches: How much garbage do you throw away after lunch? Environment clubs encourage students to bring their lunches in reusable bags and dishes. The class with the least garbage gets a prize. ●No-car days: On a no-car day, nobody comes to school in a car—neither the students nor the teachers! Cars pollute our air, so remember. Walk, skip, bike or run. Use your legs! It’s lots of fun! ●Bring your own shopping bag! Bring your own bag when you go shopping. It's a good way to reduce packaging. ●Save water! Did you know that a leaky toilet can waste 20 to 40 litres of water an hour? In a year, that would fill a large swimming pool! In environment clubs, students fix leaky toilets and sinks. ●Save electricity! Turn off the lights when you leave a room.Turn off the television and shut down the computer when you are not using them. Let's work together to make our environment clean. Could your school do some of these things?
