When cattle ranchers clear rain forests to raise beef to sell to fast-food chains that make hamburgers to sell to Americans, who have the highest rate of heart disease in the world (and spend the most money per GNP on health care), we can say easily that business is no longer developing the world. We have become its predator.
Animals raised on corn produce fattier meat, but it's not just that it's fattier, it's the kinds of fats. Corn-fed beef produces lots of saturated fats. So that the heart disease we associate with eating meat is really a problem with corn-fed meat. If you eat grass-fed beef, it has much more of the nutritional profile of the wild meat.
