If you ever want to feel really old, go to Population.io [1], enter your date of birth and country (fake it a bit if you wish), and look at how many people in the world are currently younger than you. This is both fascinating and shocking even if you enter the information for any smaller children you know (from the last decade or so).

If there are heritable traits that lead to people having more kids in a developed world environment then at some point evolution will take over and we'll start to see exponential growth again.

I... what?

Earlier quoted context omitted.

If they have their way then Nestle's bottled water will really be a luxury item you can't live without. Most likely quite literally.

In much of Asia most of the population already buys potable water in bottles. Current prices (China) are about USD$0.10/L (delivered).

Same here in bangalore, India. Price is USD 0.052/L delivered.

You are expected to live 40.1 years as a citizen of India

Well that is depressing.

Not really. You're expected to die in childhood. Survive that, you'll likely live about as long as anybody anywhere else.

One thing that is a little bit off in the analysis is the statement "China, India and Africa are (and have been for a long time) the most populous regions in the world" Actually, according to that data, Africa only overtook Europe in population between 1980 and 1990. I remember when that happened, because I'd always assumed Africa had far more people. They will, but it hasn't been for 'a long time'. It was quite rece…

Until extremely recently Africa has (with the exception of the Nile delta) been very under-populated.

Even today it's regions do not rank amongst the most populated regions https://en.wikipedia.org/wiki/Population_density (with the exception of the Nile delta)

Historically Africa had very little population growth compared to the tiny population that survived the "out-of-africa" exit.

I would speculate: part of the reasoning for this would be the lack of domesticable livestock, and why that would occur in the place where humans had evolved from simple inefficient sapiens.

With the Sahara and Kalahari, Africa will be desperately overpopulated long before it matches Europe or China for total density. There's simply a vast and growing uninhabitable fraction of land in Africa.

Increasing population pressure is actually already causing desertification that make it worse.

All I can say is, if you want to maintain that standard of living in western democracies, you'd better get used to immigration.

Maybe you would elaborate this?

I would rather say that the population growth that is only taking place outside of western democracies (with some minor exemptions), is the main reason behind the loss in living quality, as the explosion of the world wide population living below acceptable western standards puts the pressure on the wages all over the globe.

Being it through imported goods made in a country with much lower wage standards, or through stagnating wages of low skilled jobs due to immigration (please note that I just state that somebody new in some society is most of the time in more difficult position and is more willing to accept an offer considered not acceptable for longer time residents).

I understand that many societies value highly a human life but as irony had made the human life less valuable around the globe though this worldview.
