Check out this award winning video called The Story of Stuff . It is narrated and written by Annie Leonard who tells the story of where our stuff comes from, what happens to it when we throw it away and who really benefits from our crazy consumption obsession (THE MAN! no surprise there)
It is sort of depressing but if you stick with it til the end, you're left feeling optimistic about the future. Maybe we will all think twice before we buy our tenth pair of shoes this season.
