Might as well say it: 8 billion is too many, and it’s a good thing that population growth is levelling off. A decline down to ~1 billion would be fine. If we have to change retirement planning, so be it.
No other species can grow its population exponentially indefinitely. Population growth in every other species is kept in check by conflict and starvation. We have an opportunity to voluntarily limit our footprint to avoid that check.
