My girlfriend, A, got me the Living Downstream DVD for Christmas!! I am sooooo excited! Check it out here - http://www.livingdownstream.com/. It's an amazing documentary of biologist/author/cancer survivor Dr. Sandra Steingraber's book by the same title. Steingraber writes articles and books about science in general, but specifically chemicals and the environmental links to cancer. Her writing is beautiful and poetic, even when she's writing about ugly topics, and I highly highly recommend all of her work. You can search for her on YouTube, too, to see clips from her lectures and speeches.
