Carbon sequestration - using cattle herds.

Recently, developments in carbon sequestration and storage have been at the forefront of debates related to energy systems. During the recovery of oil and gas, cavities in the earth's crust are formed. These cavities can be used to pump carbon dioxide back into the crust, eliminating the negative effects of carbon dioxide on the outside environment. Another recent development also shows promise as a significant addition to carbon sequestration. Often, cattle are sourced as the cause of greenhouse gasses. Bovines release quite a bit of methane when consuming grass and feed. However, it seems that there is a delicate balance between animals and grasslands - the details of which we are just starting to understand. This idea has the potential to feed much of the third world, stop the desertification of much of the world's grasslands, and sequester enough carbon to reverse atmospheric carbon trends, let alone offset the affects of the added amounts of grazing animals. 

Triple win. 

Disclaimer: this is not my field of expertise, and I don't know the feasibility of holistic land management. That being said, based on some research which I've done, I'm confident that the idea is plausible.
