I just went to a lecture by Annie Leonard, author of the "Story of Stuff". What an amazing and awesome public speaker with a strong message as well. The Story of Stuff is a short animation that examines how things are produced and our patterns of consumption.
Have a look at their website: http://www.storyofstuff.com/ and if you have 20 mins have a look at the actual animation explaining where things come from.
Very inspiring and brings some reality to our western consumptive and obsessive behaviour!
