Hah true, wasn't even thinking of that angle, just the general badness of getting to the bump in the first place. Maybe mostly a historical issue by now though, I guess bulk of population is already near or post bump...

What I hadn’t considered before is how making agriculture more intensive helps the environment— higher yields mean that more land can be left for, for example, wildlife and trees. So there’s a lot to be won for everyone in eg sub Saharan Africa.
