Epigraph:

The sun and the moon run their courses according to a fixed reckoning.

And the stemless plants and the trees humbly submit to His will.

And the heaven He has raised high and set up a measure, that you may not transgress the measure.

So weigh all things in justice and fall not short of the measure. (Al Quran 55:6-10)

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.
