I think the solution is somewhere in between. There is a lot more cows today than there was 200 years ago. The negatives get compounded with CO2 and methane being released, plus the water and energy used to make beef over other meats or sources of protein is much higher. Though yes we did evolve to eat some meat. But the average American eats a lot of red meat and the average American has a less than healthy cholesterol level. So let's just eat less red meat. If we all cut down our red meat consumption by 50%, the environment would be much better off, we would be healthier, and we would still be able to get the nutrients we need from meat.
