The only way to control population growth (and a quite reliable one) is
to enable a population to have enough food to eat, shelter, education,
employment and health care to feel secure.


The only one?


Yeah,, thats mad.


Off the top of my head...


War,


Even WW1 and WW2 didnt have much effect on that.


Or even the Vietnam war on the population of vietnam
https://en.wikipedia.org/wiki/Demographics_of_Vietnam.


Pestilence,


Its only the black death that has much of an effect
like that, presumably because people keep ****ing.


Famine


Ditto.


OK, famine, war, pestilence are the mechanisms that have controlled human
populations over the vast majority of human existence.


But clearly dont much anymore given that even HIV/AIDS
hasnt has much effect on population even in africa.

All animal populations tend to reach a point where further expansion is
stopped by lack of resources, this may be a steady equilibrium or a crash.


Humans work differently to that.

In (very) recent times expansion of resources has exceeded the rate of
population growth. But this is only in the last few hundred years, in the
first world, much less in the third world.


Thats not really true now the third world.

If population growth were to continue to grow


Its already dropping EVERYWHERE now except where
the birth rate is right down in the noise already,.
https://en.wikipedia.org/wiki/List_o...#1950_and_2015

And the TOTAL of India and China, by far the two most
populous countrys isnt even self replacing now.

we could reasonably expect limiting pressure from resource limitation to
reassert itself.


Not anymore.

Indeed, you might already consider that the green movements are the start
of this pressure.


They dont have any effect on populations.

If you are to interpret these answers in the context of the question how
to limit population growth in the immediate future (30 years or so) I
grant you they are weak. Although, Thermonuclear war is still a very real
danger,


No its not. It was never going to happen.

which might reduce both population and resources.


Not going to with resources.
