"Why is it that an industrialized system, deeply dependent on fossil fuels and chemical treatments, is promoted as viable, while a much less damaging one is rubbished and condemned as unfit?"

The sustainable farming movement, cradled in Northern California, has gone mainstream, challenging the industrial model that has ruled American farming for more than half a century.
