25% is an astonishing figure. I would have guessed in the low single digits. Apparently cattle grazing accounts for much of the deforestation of the Amazon-area rain forests.

One thing that can be done about it is cutting government subsidies. The meat industry is a huge political force in the US, and I suspect everywhere else, and in the US they get loads of government money in one form or another. It goes hand in hand with subsidies to the corn industry, much of which goes to feed. And so we have meat that is incredibly cheap, insanely cheap in the US because the farmers producing the feed and the ranchers raising the cattle are all subsidized by tax dollars.

The first step might be to redirect that public money to more sustainable food production.

Wait... I just realized that this figure is for grazing areas. Most US cattle are penned up and force fed corn, a practice my Canadian cattle farming friends are quick to point out is not used in Canada. So the figure, if you were to include all the area used for feed-based corn production, is actually much greater.
