And we’re not talking about just a few years of extra rain. We’re talking about a climate that was so wet for so long that animals and humans alike made themselves at home in the middle of the Sahara.

NOTE: Statements in this talk have been challenged by other scientists working in this field. Read more here: https://blog.ted.com/allan-savorys-how-to-fight-desertification-and-reverse-climate-change-criticisms-updates/ "Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And terrifyingly, it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes -- and his work so far shows -- that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.

As the Gobi Desert expands further south - engulfing an average of 3,000 square kilometres every year - entire communities are forced to relocate, becoming climate refugees. In a bid to combat this phenomenon, Chinese authorities have been erecting a so-called "Great Green Wall" of vegetation. In some areas, positive results are beginning to show.

#AmazonFires In an effort to fight climate change, the Sahara Desert could be going green... literally. Plans are being made to terraform the entire Sahara desert; changing it from a dry, barren landscape to a lush green space. If successful, the transformation could remove 7.6 billion tons of atmospheric carbon yearly. How could we change the nature of such a vast, isolated landscape?

Terraforming Sahara, a new and thought provoking idea that could change the fate of this planet. Of course by doing so we can fight with the climatic changes. Imagine a green Sahara can protect us from the effects of global warming and it can also deal with the carbon dioxide emissions.
