I'm not sure I understand. Nowhere did I say anything about actually putting bison back out there in the way the settlers found things when they moved in.

But instead of planting lots of corn and feeding your barn full of cattle with it you can also own that same piece of land and sustainably make grass fed beef. Said beef would keep your soil fertile by trampling and shitting on it.

In addition to this your vet and meds bills will be lower to non existent because you don't get the same disease issues you get in cramped barn quarters.
