Permaculture - Farms of the Future

I just stumbled on this video on permies.com forums and it is pretty good. It focuses on the energy cost and declining world supply and how our food supply is literally in danger. Very nice to see how the host of the show progressed in her understanding of permaculture, and I think we completely underestimate the power of synergy, diversity in plant, animal, insects, and how nature was designed to work. Thinking of the garden of Eden and how God put Adam and Eve there to tend the garden. I just visualize how they must have had a fascinating understanding of these complex systems, and just how stupid we literally have become. Anyway I thought you might enjoy the video.
