Have tasp, will travel.
Pretty much irrelevant unless those countries enact net-ZPG or net-0-migration immigration policies and only partly relevant even then. The half where that is NOT the case are more to the point. Those are the ones whose fecundity is passed on culturally or genetically to a larger fraction of the next generation.good news for the planet - a new study suggests half the countries of the world have birth rates that show a population starting to decline . . .
If, for example, you succeed in suppressing birth rate by persuading people that abstaining from reproduction is the moral course, you are simply breeding for people who can't be persuaded or don't care. Last I checked, we are not being overrun by Skoptsy. Whatever environmental factor you tweak, natural selection will work counter to it.
Much more to the point.World Population Clock: 7.7 Billion People (2018) - Worldometers
71 million more people so far this year, which is more than the entire population of over 90% of nations.
It would if it actually happened. But I fear the opening post is naively optimistic. Kudos for making the point though & keep on preaching. It's the only sermon that can save us from planetary disaster. It apalls me, that even in the SF community, so few recognize how tragic our failure to curb the growth in human population is, how much we've already lost because of it, and how much it still is likely to cost us in the future. I fear it is a crucial part of the complex of developments that will constitute our Great Filter moment. Niven & Barnes' Saturn's Race is a much under-appreciated novel touching on this. In it one of the characters remarks, "The ghost of Asimov haunts us still." Yeah, damn straight.It might give the planet a chance
Of course. What can't survive in its present form are the ridiculous Ponzi schemes politicians have used to buy support from the well-meaning gullible and those who simply don't care about the future. Not only can "a global economy" (actually you can just say "people") "survive" a ZPG regime - they can prosper. On a per capita basis, we should do much better actually.Can a global economy function with a falling or static population?
I presume that's not meant literally, because unless you want to resurrect a Hoylean CC cosmology, then the impossiblility of "perpetual growth with no limits" is so obvious that it is pointless to note it. Nor would the rate of population growth have anything to do with it.No, not on the "perpetual growth with no limits" model...
So I presume you meant that Ponzi schemes reach a limit when you run out of fresh marks (as in children forever outnumbering parents), in which case you are absolutely correct.
But some might interpret that to imply that a rising Net World Product per capita (roughly equivalent to "standard of living") requires a continuously increasing population - but that's hogwash, as even a rudimentary study of economics will reveal.
