A HUGE area of the land on our planet is becoming desert, which contributes to climate change, wars, etc. This man (a biologist and professional ecologist) has a new theory of desertification, and how to reverse it. Supported by compelling research, and the approach is being applied on five continents. He has project results and comparative photographs to show in this talk - takes about 20 minutes to watch.
Very hopeful.
