Here is an amazing talk by author Michael Pollan about sustainable agriculture from his April 19th talk at the Minnesota Landscape Arboretum. Over the course of this 53 minutes piece, He discusses “what is organic?” and issues like organic foods being flown in from around the world v. locally grown foods that are not organic. What is actually better environmentally?
Additionally, he gives an absolutely fascinating discussion about a self sustaining cattle/chicken farm. Though you have to wait until he is 2/3 of the way finished with his talk before you hear about this great farm and how it works.
alphamonkey sez: Pollan wrote the excellent ’The Omnivore’s Dilemma‘ (from which a good deal of this speech is adapted), as well as the wonderful ’The Botany of Desire‘. Both are almost certainly required reading for anyone interested not just in organics and sustainable agriculture, but how the plant world has changed to fit our wants over time.
