I love our environment,and I make less pollution. Let's clean up the world and the school yard.In North America,students join "Environment Club" to make less pollution.In a club,people work together.And in an environment club,the student work together to stop pollution.They do the following things to make our environment clean.1.No-garbage Lunch.How much do you throw away at lunch? Environment club encourage students to use the ruzable bag and dishes.2.No-car Day.On the No-car Day,nobody comes to school in a car——Not students,Not teachers! Cars pollut our air, so remember:Walk,skil,bike and run.Use your legs,It's lots of fun!3.Turn off the water.Do you know that a leaking toilit can swate twenty to forty litres of water an hour. In a year, it would fill a big swimming pool.So the students in environment club often fix the leaky toilit and sinks. If you see the tap is leaking,do you turn off it?Do your school do the same things for stopping the school yard?Each one makes less pollution,our environment will be very clean!
