This is a really neat project that approximately 1500 Sri Lanken Girl Guides did at a series of eco-camps. They went on a campaign to end the use of 'sili sili' (plastic) bags, and one of the things they did was walk around busy shopping areas and look for people carrying plastic bags. When they found some one, they explained the effect these bags have one the environment and offered to exchange their plastic bag for a cloth bag that the girl guides had made.Their project was amazingly successful, and even though it was a long morning collecting bags, they were very proud at how many bags they had collected. (This sounds like a really good project for the environmental volunteer project, to help earn your Canada Cord). The original artical can be found here:
