I just finished viewing this documentary produced by the wife of the late Jerry Garcia. I knew some of what was contained in this video already, but did not connect some of the practices to one another until viewing this vid. This documentary discusses Genetically Modified foods, Monsanto's questionable practices concerning patenting seed and plant life, "terminator seed" technology, and more.
I highly recommend this movie. You can also learn more at their website: http://www.thefutureoffood.com
