Greening the Sahara (means Desert in Arabic)
Here link is an example of what people can do to regreen the Sahara. My dream is to combine the Permaculture and Solar Energy to regreen the Sahara, which is a very good initiative for the climate.
Enjoy this film realized in the lowest land in the world and called the death valley, near to the death sea. You will see that regreen the deserts is not an utopia but a realistic dream.
