It’s a match made for the ECW: John Mackey, co-founder of Whole Foods, versus Michael Pollan, author of The Omnivore’s Dilemma, the best-selling critical overview of modern industrial foodways that reveals Whole Foods to be … just another big supermarket chain! In an open letter, Mackey has accused the writer of not doing his research, but this afternoon they will meet face-to-face and finally resolve the question of who’s handier with a folding chair. Actually, they’re just going to debate, after Mackey gives a presentation modestly called “The Past, Present, and Future of Food.” It’s happening at the University of California, Berkeley, at 10 p.m. our time; you can see it Webcast live here — or wait for our breathless take on the proceedings tomorrow.
