The documentary "How to Save the World: One man, one cow, one planet" is a terrific introduction on how "The Green Revolution" in India was really chemical warfare on the earth, and how he has dedicated his life to building sustainable farming in India based on the work of Rudolph Steiner and Biodynamics. Biodynamics is really a comprehensive lifestyle that incorporates and sustains communities. This is the kind of future humankind can have.
I was also impressed by a quote by Ghandi that appeared in the film, and it sums up how this kind of farming is also a political act, supporting a democratic future.
Ghandi's view of Democracy
My notion of democracy is that under it the weakest should have the same opportunity as the strongest... No country in the world today shows any but patronising regard for the weak... Western democracy, as it functions today, is diluted fascism... True democracy cannot be worked by twenty men sitting at the centre. It has to be worked from below by the people of every village.
