City living is eco

I've been helping out the caretaker in our apartment building. He digs through the rubbish looking for cardboard and glass, and finally the body corporate has asked everyone to separate those and he will collect. Unfortunately this is purely a cost driven exercise for this bloke, so he isn't interested in anything else of limited value, but I was thinking of starting a compost heap (a friend of mine is organising a worm one in her block). This got me to thinking how it's so much easier to co-operate when you live in close quarters... city living can be eco sometimes. All we need is lift sharing or car sharing and then we're sorted. Hmmm..
