A fascinating Ted talk by Allan Savory, How to fight desertification and reverse climate change, suggests we should introduce large herds of cattle to the vast areas of bare ground across the world.
In the US it is estimated there were between 30 - 200 million bison on the prairies (American Buffalo: Spirit of a Nation). Makes me wonder if we might reintroduce buffalo, in a big way, to our prairie regions that have become barren.
It seems that there is some interest by hunters in Montana to reintroducing wild herds of bison, Bringing back bison, but this movement is facing opposition by ranchers.
