Now Hear This - Conscience-in-chief, Michael Pollan puts it all together in one talk

Some may say that Pollan over-dominates the issue but no one articulates the principles of the growing food revolution like he does. KQED aired this talk three days in a row and if you missed it, check in to the Long Now Foundation website where it will soon be available as a podcast. It is amazing that Pollan has such a comprehensive view. My favorite, for the moment, point is that of all the ills in the world today (most of which make mortals like me feel overwhelmed) reforming the food systems is empowering. We are the change we want to see by the choices we make when we procure our food.

Here is the program description and link to Long Now Foundation:
Michael Pollan Deep Agriculture (The Long Now Foundation): Deep Agriculture: Re-solarizing the Food System to Fight Climate Change and the Health Care Crisis -- This special program consists of a seminar on long-term thinking produced by The Long Now Foundation and featuring Michael Pollan. Pollan will describe his program to transform American agriculture as a "sun food agenda." Hes the author of In Defense of Food: An Eater's Manifesto and The Omnivore's Dilemma: A Natural History of Four Meals. Pollan is also the director the Knight Program in Science and Environmental Journalism at UC Berkeley. This seminar about long-term thinking is hosted by Stewart Brand and was recorded at the Herbst Theatre on May 5, 2009.
