After courting controversy with my previous article, I thought it appropriate to perform some experiments on myself, as is the tradition of all the finest Australian troublemakers!

Walking in Bateman’s Bay a couple of years ago a self-confessed ecologist opened his back pack to show me its contents. It was full of rubbish. He pulled out a can and explained that wherever he was in the world, he always carried a bag and picked up any rubbish he came across so as to leave any place he visited in better condition than before he came.
