I’m only comfortable with more humans if we make serious efforts to increase the percent of vegans/vegetarians, or reduce the amount of meat needed by human, given how wasteful meat is to land use.
[limited hunting of deer/pigeons/waterfowl could be ok, but people would still need to eat way less meat than they do now]
maybe, just maybe, cultured meat will come just enough time to save us. But the probability range of this is still too high for comfort.
I very strongly believe any pro-fertility incentives must be coupled with incentives to decrease meat consumption/increase vegetarianism (or increase % of power from nuclear, given that excess solar energy will also destroy habitat).
EO Wilson once advocated that 50% of the world is set aside for wilderness. Maybe that’s a bit too ambitious, but I think 35% would be good enough to preserve enough biodiversity. Taiwan/Hong Kong/Japan are all densely populated and have roughly that % of wilderness/forest (they also rely a lot on seafood, which does not destroy wilderness , but is still inherently a limited resource given overfishing). People get huge health/happiness benefits from nature exposure too, esp when the nature is close to where they live
“If everyone agreed to become vegetarian, leaving little or nothing for livestock, the present 1.4 billion hectares of arable land (3.5 billion acres) would support about 10 billion people”—EO Wilson
