In this TED talk, Mark Bittman (a food writer) describes the prevalent approach to food in the US as a direct result of agri-business (and its effective lobbying / control of US agencies), and ascribes to it a level of danger equivalent to the atom bomb. Not so much, interestingly, because of the negative effects of the US diet on our health (although he does discuss that too), but primarily because of its impact on global warming and water supply.This is a talk worth watching.
