That is certainly true, but livestock is often eating row crops. A significant chunk of soybean meal and corn goes to feed livestock [1] [2]. If those row crops were consumed directly by humans instead, it would require a lot less land. [3]

You need more than just raw calories, though. How much plant food would it take to match this in terms of protein and B-vitamins?

So that's just 1 pound of beef.

You could get about 500 pounds of that raising a cow for a couple of years and slaughtering it.

What inputs would you need? Not too much, if you have grass, which a lot of the earth does. Let the cow graze, find it water. Optionally fatten it up at the end w/ some grain -- probably a better use than making ethanol out of it, at least.

We used to have millions of wild buffalo roaming North America. They were a dietary stable for many Native American tribes.

Were they really living in a less sustainable way than modern vegans picking up Impossible Burgers from Whole Foods?
