I don't have an exact answer to that but let's say it does. It is a fact that it creates a product of incomparable nutritional quality when it comes to protein. Just look up bioavailability and nutritional data comparing animal vs. vegetable protein.

That being said, animal farming doesn't have to take up any resources that aren't renewable.

It's nonsense that it's inherently unsustainable and that critique is more applicable to industrial agriculture, which vegetable proteins will also demand.

You have to try and make it as apples-to-apples as possible for a proper comparison, i.e. land yields, energy input, nutrition quality, etc.

We'd be all healthier if silage was fed to farm animals instead of humans.
