A brilliant assessment, by my hero Vandana Shiva, of the magnitude of what we are up against. I highly recommend watching this video below. http://www.youtube.com/watch?v=CGCrbX2vUXc&feature=share
What can we do about it? Create small, sustainable, natural farms with hand tools. If you can't do that yourself, support those who are attempting to do this.
Raise heirloom and heritage vegetables, fruits, and grains; save and share the seed. Raise, and breed out heritage livestock.
Spend as little money as possible, on all the things that support the industries that are destroying the planet. Every dollar you spend, is a vote for what you want more of. "Vote" for the environment every chance you get.
