Oh, so populations of animals with low fertility rates don't die out :/ |
Three aspects:
#1>
Results = Reality .. weather that result was 'chosen' or not.
'choose' to have a child .. but fail to conceive .. Result = no child = reality.
Choice has finite influence on result ... Result = Reality .. even if the result is not what one 'chose'.

That low fertility group you describe might die out , or it might not die out at all .. it might thrive , it might not thrive .. it depends on more than just fertility rate ... Survival of the fittest .. fittest does not necessarily mean the most fertile.
There have been numerous species that have died out .. even if they had a higher fertility rate than other species that did not die out.
A high fertility rate is only one contributing factor toward how 'fit' a group / species is in a given environment / context.

Yes Observations to-date (reducing population % growth rate) .. does not agree with your previous hypothetical :
"if we breed out those who choose to self-reduce"
Soo far ... data , to-date .. refutes .. shows that specific hypothetical is not happening.
If that changes in the future .. than it will manifest itself as a increasing % global growth rate.

My take .. major (globally significant) conflict (war) has numerous other destructive / damaging / counter-productive effects ... it doesn't just kill people.
And (My take) this last ~40 years has had a faster and more globally effective negative contributing influence on total global human population ... than any war in history ever has.
WW2 was about ... ~0.6%/yr influence .. around ~14mil/yr .. for all of ~6 yrs.
The ~2Billion .. not born due to reduced % growth rate .. has been about ~0.7%/yr influence .. ~50mil/yr .. on average for ~40 years .. this is larger total , faster , for longer period of time.
