Here’s a couple of talks from a pair of heavyweights in their fields at the PopTech conference last year.

Michael Pollan, author of The Omnivore’s Dilemma, has become very famous in foodie circles in the last few years. His talk (Youtube, 15 min) goes deeply into the world food system, how it’s failing us, and what needs to be done.

Will Allen is the founder of Growing Power, one of America’s most impressive community-based organization. He talks (Youtube, 24min) about how hey’ve set up sustainable, organic food production in poor rust-belt communities on a truly impressive scale. Their activities include everything from massive sophisticated composting programs to turning parking lots into gardens. They run greenhouses, aquaponics and other cutting-edge programs, and do it all in the poor communities themselves.
