The Story of Stuff is a well-made online video highlighting the dubious nature of our consumer-driven economy. I particularly like the third part (distribution), which among other things discusses the externalization of costs & impacts of consumer products.
As much as I agree with the content of this video, however, I wish that it was less filled with rhetoric and instead contained more fact-based discussion. The website contains links to organizations that research many of the claims made in the video, but when a presentation is as one-sided as this it inevitably ends up being a sermon to the choir and failing the more ambitious goal of swaying the opinions of a larger audience.
