Yeah, maybe not all of the article but it still is. Pro life ass propaganda without scientific merit.

Population is separate to climate change.

They are still talking about it in both articles on the frontpage including this shitty one. wtf is wrong with you all telling me to read the article without reading it yourself?

Birth rate is not a law of nature that can be naively extrapolated. Increased pace of technological development implies an increased pace of societal changes, which will impact birth rate.

Predicting birth rate for 2060 from today might be roughly equivalent to someone in 1850 trying to extrapolate birth rate to 1950. They would have been completely wrong because there was no way they could predict the level of development.

Even ignoring that, shouldn't we expect birth rate to be autocorrelated, as the impact of having children, and therefore people's decisions to do so, would depend on the population count itself?

> Forget About Overpopulation, Soon There Will Be Too Few Humans This can be easily and summarily dismissed if you know anything about minimum population numbers. Humans will never, through simple declining birth rates, reach the low-or-sub-1000s numbers that would result in there being too few humans to maintain genetic diversity. https://www.livescience.com/minimum-people-to-survive-apocal... > how many people woul…

Other than genetic minimum population numbers, there should be civilization minimum population numbers, and I'd suspect modern technology would allow for a few hundred(?) million people to hold up the same standard of living and progress.

The article is heavy on criticism of population decline and light on an argument of why it is so bad. As a parent in the USA I also don’t buy the argument that it is all education and birth control driving these changes. Many of my acquaintances simply cannot afford the costs of multiple children. And for others climate anxiety makes them question the future.

> Many of my acquaintances simply cannot afford the costs of multiple children. I can't speak for your friends. But I think that when someone says "can't afford" what they really mean is "I'd rather spend that money on something else". Some people literally can't afford children. But those in the middle class (or better) in the US certainly can . It would just take money away from other parts of their lifestyle: the…

No, what many of us mean is that "We can't afford to give a child the kind of support and resources and opportunities that a responsible parent knows it is their job to provide."

Many of us grew up poor, and saw people around us who didn't make it out. Many of them are still poor bordering on destitute, some are in prison, a couple I know are dead. Until I can *reasonably guarantee* that I'm not putting my kid in that position, I'm not going to have a kid.

I've spent an awful lot of time in both Croatia and Japan, and the problem looks more or less the same in both places. Croatia has had sub-replacement fertility for decades -- plus the migration of young people to other EU countries that offer higher salaries, or to Zagreb if they can't find a job in Denmark or Germany. Japan has had sub-replacement fertility for decades -- plus the migration of young people from sma…

Transportation revolution. Cars that fly themselves at high speed. Superconducting maglev trains shooting between downtowns and between suburbs. Cutting the distance is the only way to expand and combine low cost of living with economic density.

"The more people there are, the more solutions to problems will be found." Has not been true so far, I wonder at what population amount, will this start working ?

This seems pretty logical to me.

If we assume that distribution of professions scales linearly with population size, a 2x increase in population means there will be twice as many researchers and inventors that can dedicate their life to finding new solutions.

I would assume that the scaling is not linear. Do we need twice the workers in agriculture to feed twice as many people? With our modern agriculture technology that seems unlikely to me.

One could argue that this is counter-balanced by diminishing returns, as in: 2x the amount of researchers won't have 2x the output.

But it's hard for me to see how "more people = more progress" is false.

I had a long conversation with an anthropologist so studied the emergence of agriculture, who argued that it wasn't invented but instead adopted by necessity. He pointed out the huge host of health problems that came with agriculture: hard labor; poor quality food; diseases from living densely. Life expectancy dropped from the adoption of agriculture until well into the industrial revolution, with the adoption of pub…

So what were the necessities that prompted the adoption of agriculture?

The disappearance of the big animals that could sustain hunting.

10 half-starving farmers could beat 1 fat hunter gatherer in a fight.

Why didn't the non-farming population expand to the limits the way the farming one did? Why aren't there two half-starving hunter-gatherers?

It's got some interesting data that I haven't seen before on falling fertility rates and projected future populations. I don't agree fully with the claim that a growing population is all upside. Nutrient density of produce has been falling for decades, so there are some problems that I don't personally see as something that can reasonably be hand-waved off.

But if you are someone terrified about the future and one of your pain points is overpopulation, the argument seems to make the case that populations are likely to begin falling at some point. (Granted I didn't click through to any of the cited links, so I am basically taking their word for it./pedant)
