This is all great info. Thank you.

As for land use, are we not comparing apples and oranges? My understanding is that ruminant animals could be raised on land that we wouldn't be able to grow plants (for human consumption) on? Do you know if that's true?

The evolutionary arguments are just hints as to where we need to be careful. I believe there is very much a lack of epistemological humility in the sciences. Scientific papers are often treated like mathematical proofs! When in fact tomorrow's science will refute a significant portion of today's science. So I keep that evolutionary information in mind while skeptically looking through a lot of today's science.

Also, agreed we would need to crunch numbers on deaths and that's it not that simple anyway.

I guess overall we are agreeing there is nuance everywhere here. Thanks again!
