Financial blogger Felix Salmon has an essay in Foreign Policy called "How Locavores Can Save the World" -- expanded, by the way, from a wonderful blog post he wrote after attending a panel discussion on world hunger at the Davos World Economic Forum in the company of Blue Hill Farm's Dan Barber. Salmon usually focuses on issues involving economic crises, monetary policy, complex derivatives, macro-economics, and governmental oversight of the financial markets, but here he's talking monocultures, sustainable agriculture, and transgenic seeds.
