Presentation
In North America, many students join environment clubs.
In an environment club, students work together to reduce pollution and protect the environment. The following is a list of their activities and advice.
I’m a member of an environment club.
·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.
