Interesting link. Of course most of the members are meat eaters. But,
devotees in US could source dwarf breed of cows through these links.

Cows grazing - solution to all climatic problems

"Desertification is a fancy word for land that is turning to desert," begins
Allan Savory in this quietly powerful talk. And 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.

Allan Savory works to promote holistic management in the grasslands of the
world.
