We would need to expand the cropland growing food for humans, yes. But there is a lot of cropland currently growing types of corn and hay that we as humans can’t eat, just so we can feed animals and get a less than 20% return on calories from the ‘food’ we get when we eat animal muscle and organs.
Which is why our total crop land use would go down if we didn’t eat animals: we need less space to grow calories and nutrients for us that we do to feed the animals we eat. So much gets wasted with the current process that it is unsustainable, and we need to start shifting this now to avoid running into severe land and water deficiencies with the changing climate.
about 10% of the energy and nutrients animals consume get passed down into humans (ie for 10kg of feed we get 1kg of meat - i’m actually surprised it’s even this much!)
that means if we get those nutrients from plants directly for every 10kg of plant we get - perhaps not 10kg since there’s still waste, but you don’t waste 90% of the plant to consume
like when cocal cola is stealing the water of whole regions by taking it for basically free, and selling it?
or like when in south spain people have no water, because all those vegtable farms?
even so, we would still probably expand cropland to feed a vegan world

even poore-nemecek doesn’t say this. do you have a source that does?
well that part is just logical
