Mark Shepard is someone who I've followed for a long time. The venue in this video is organic farming, but Mark is best known for his work in Permaculture. In this video, he covers agroforestry, carbon, politics, profits, & so much more. Our politics are exactly the same when it comes to food & the environment. This guy is a proven performer, not some egghead.
