If you haven't checked this out yet, I highly recommend you do:
It is a 20 minute video put together by a woman by the name of Annie Leonard about consumerism and how it is hurting our natural resources--and so much more. I can't do it justice. You just have to go watch it for yourself. It is jam-packed with facts and very well-written. She packs a lot into such a short video. After watching the video, if you click around the website--she provides the full script of the video complete with references so that you can see how she has proof to back up what she says. I think it is a brilliant video.
