While in principle I agree fossil fuels aren't required, in practice it is much more difficult to convert transportation, manufacture and extraction than most realize Also suspect modern agriculture's conviction that the crop is an empty vessel requiring synthetic fertilizer is long overdue for reconsideration. Organic ag can be as productive as industrial ag, at far less energy/materials cost, but it will require much more human effort. While this is a very serious tradeoff to make I would argue it is worthwhile in the long run.
