If you want to discuss this you’re going to have to get more specific
Which part of this? Marginal land? That's a very specific topic. Why should we bring in 100 different variables unless you can show those variables matter to marginal land.
Or are you sayign there's some prima facie point I'm missing where "nothing but wild animals on marginal land" will produce more sustainable food than "cattle on marginal land"?
Or are you just trying to get me to provide enough information to overspecialize my rebuttal so that your side need only say "ok, everything but that"?
My argument on marginal land is prima facie so far. I picked it because it seems obviously true on the surface, so I can let you provide your points to try to blow it up. I'm referring to the land use problem, which is the often-cited vegan argument that livestock land could be instead used as forests or croplands to sequester carbon.
If you want to contest the 2/3 marginal land number, I'll cite a few references, but it seems an odd number to consider "magic"
