     Many solutions we seek with regard to achieving sustainability(可持续性) are within our reach.
That's the lesson our school's Environment Club has learned over the past two years. We've reduced
the amount of our waste at our school by 25 per cent.    1     We have the evidence we need to
suggest we are making a difference. If you are interested in leading your school on a similar journey
of change, here are some tips.

   Examine the garbage can to find out how much of your school's garbage could be picked out from
the waste stream and be reused. We found that more than 80 percent of our waste could have been
reused, recycled or composted(制成堆肥).
    Prepare dustbins there.
      3    You will find you can cover the cost of the purchase of the dustbins within a few months simply
by selling the bottles and other items you collect.
    Compost the waste.
    Start a composting system in your school. You may reduce your waste by as much as 50 percent.
Be sure to talk with your teachers and your cafeteria staff to get them onside.
    Share your success.
   Let your community know what you've accomplished.    4   Ask your teachers if you can talk to
their classes, let your parent group know what you're doing, and present a report to the president of
your school.
