There are a lot of places that still have Elizabeth as the queen. I think most have just not got around to getting rid of the colonial ties. Why on earth does Canada still have a governer general?
Because it's a perfectly functioning constitutional democracy and changing that constitution will be far, far too difficult. Plus many Canadians wish to keep the Monarchy. I certainly do. It's not like the US is getting rid of its President just because white wigs are no longer in fashion, or some other superfluous reason.
I wonder if anyone has taken into account the population growth question that results and what the impact on poor regions like Africa that suffer most of the deaths?
.... this has the potential to equal millions more people if even a relatively small portion (25%?) go on to produce a family with 4-6 offspring.
It's been repeatedly shown that improved life expectancy and a higher standard of living lowers population growth. If you know your first two children will live relatively healthy and prosperous lives, there is a diminishing incentive to continue to produce children. The less you are sure your kids will live, the more you'd want to make some replacements just in case.

Polymer physicists are into chains.
