In most parts of the world, many students help their schools make less pollution. They join "environment clubs".
In an environment club,  people work together to make our environment clean.
     Here are some things students often do.
     No-rubbish lunches.  How much do you throw away after lunch? Environment clubs ask students to bring their
lunches in boxes that can be used again.  Every week they will choose the classes that make the Ieast rubbish and
report them to the whole school!
     No-car day.  On a no-car day,  nobody comes to school in a car,  not the students and not the te'achers! Cars give
pollution to our air, so remember:
     Walk, jump, bike or run.
     Use your legsl It's lots of fun!
     Turn off the water! Do you know.that some toilets can waste twenty to forty tons of water a half hour? In a year,
that will fill a small river! In environment clubs, students mend those broken toilets.
     We lovc our enyironment.  Let's work together to make it clean.
