If you are in one of the cars rushing by on the freeway, your efforts are just as important as mine as a farmer to develop post-fossil fuel agriculture. Part of the solution is political. To a large extent, the present rural landscape in much of America is the result of federal policy that subsidizes massive production of just a few, easily industrialized crops — corn, soybeans, wheat. This policy has caused the loss of soil, biodiversity, localized food markets and farmers, resulting in a fragile system dependent on increasingly tight and insecure supplies of petroleum.
