I think the idea is that if you used the land to grow food for humans, you could feed more humans than if you used the land to grow feed for livestock and then eat that livestock. I forget what the numbers are, but they are pretty compelling. This isn't just an opinion, it's a verifiable fact. I just don't know the numbers off the top of my head.

Here are some numbers.
