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"?
