The same people that believe we came from apes think we're not supposed to eat meat. So evolution gave us these choppers to eat...grass? I guess if you factor in all the crud they put in the animals feed, all the shots they pump into the animal; then the horrible conditions of the slaughter houses that not eating the meat from American cattle ranchers is probably correct. There is no argument to the contrary if the animal is raised as organic and free range, with no hormones or vaccines. Humans are supposed to eat meat, just not pumped full of crud. And, then theres, pink slime...
