If you haven’t done so already I really recommend watching the Story Of Stuff. Here’s what the Wikipedia entry has to say about it:
The Story of Stuff is a web-based documentary about the life-cycle of goods and services.
The documentary, released online on 4 December 2007, is narrated by Annie Leonard, who has an undergraduate degree from Barnard College and a graduate degree from Cornell University in city and regional planning. It is sponsored by Tides Foundation and The Funders Workgroup for Sustainable Production and Consumption, with Free Range Studios to produce the film.
