Geoff Lawton Ted Talk on Permaculture

This is a powerful TEDx talk where Geoff Lawton explains about how permaculture can build fertility and have a positive impact on climate change now with what humans can do and society has to offer.  He talks about how education centers teaching permaculture with demonstration sites in both urban and rural centers are the key to make this happen and that the Middle East is a prime opportunity to demonstrate this and has the potential to re-green the desert.
Geoff Lawton is an internationally renowned permaculture expert, consultant, and practioner who studied under Bill Mollison.
