They’re talking about pretty important issues, and in a way, each seems like something of a caricature of his side. Grant wants to solve the world’s hunger problems through the magic of (Monsanto) technology, while Pollan argues for many local, sustainable solutions, developed at a grass-roots level, by people so hungry they can barely keep themselves alive. There’s an element of evil corporate suit vs. idealist college professor, but that’s as much a pre-existing stereotype as it is a reality. They’re both pretty astute and articulate.
It’s good viewing, even if few of the world’s problems are solved by the end. Most people don’t want to eat crops that were developed in a lab, nor can they afford grass-fed steaks from New York’s Blue Hill. But at least debates like this get companies like Monsanto out of the backrooms of government, and idealists like Pollan out of the ivory tower.
