You can make a difference in your local school! Here are a couple of ideas:
Does your school have recycling? How could they not have recycling?! Campaign in your school to get recycling. If necessary, set up a system for them.
Run a campaign in your school to promote ‘restorative justice’, which is all about a school system that focuses on reconciliation not punishment, honest discussions between parents, teachers and students rather than expulsion or detention. It’s already happening at St Thomas’s school in Christchurch. More info from http://www.restorativeschools.org.nz/networks
