Yes. A cow is a machine that turns vegan food into beef at a low efficiency ratio. Most of that vegan food is edible to humans. If it’s not being eaten by cows, it could feed many times as many humans. So we will always have the resources to feed more vegans than we currently have carnists.

To answer a common counterargument: yes, I’m sure your uncle and aunt raise their cows on grass, but when it comes to big business, it’s corn, grains, and other human edible crops. Big businesses are so much huger than your uncle’s farm that the math still works out the way I said it does.
