Michael Pollan, author of In Defense of Food and The Omnivore's Delimma lectured recently as part of the Authors@Google series.
Here's the video. Really good stuff.
Pollan, a professor Science and Environmental Journalism at UC Berkley, has written extensively about everything from the health implications of the ubiquitousness of corn and high fructose corn syrup to the politics of the way we eat.
There's also an audio interview with him from NPR's Science Friday here.
