> What Is Our Global Limit?
- that, methinks, would depend HUGELY (i.e. by orderS of magnitude) on
0) the starting point: do we start our model at some fictional (healthy) steady-state "equilibrium", or do we start in, for example, a seriously me$$ed up, instable, "chaotic" (near-singularity) situation like Earth is currently in
1) in what state we want to sustain Earth (like with polar bears left? tigers, clouded leopards, lampreys, ... .. . .. ... left? how much (if any) of the Wild left?) and for how long: centuries, millennia, or to the next quarterly financial report ?
2) on the neuroticity of humankind, as e.g. defined as the ratio of resources (material and effort) wasted+spent totally / resources spent to fulfill human needs (which measure seems to be (sharply) increasing)

as f*d up as Earth currently is, rule of thumb: the less humans the better. Gaia will take care of that (unless we manage to do it by means of our choice (which would be a lot less cruel), and pretty soon)

If the statistics from the article are correct then we have reached our upward limits and modern society and awareness are holding the population static. That is actually very good news, it means the global population is not growing.

"By the early 1970s, fertility rates around the world had begun dropping faster than anyone had anticipated. Since then, even though the population growth continued, the population growth rate has fallen by more than 40 percent."

Yes, this all good news Kit, now, how to simply feed the starving has become nothing short of a NASA plan.
Somehow, the verb "to give" has become a major social, economic and political mountain.

Population growth needs an EVENLY DISTRIBUTED trend! People in parts of the world which CANNOT sustain growth are still growing. Education and contraceptives are the answers.

Something to think about that Iread on another site -

Question: With birth rates, fertility rates, and growth rates all falling, how can our population keep on steadily rising?

Answer: Momentum. Although couples are creating fewer of us, there are more couples creating those new people, which makes more of us. For example, China’s 1.5 TFR is way below “replacement level fertility,” and yet their natural increase is 6.6 million per year (2011 estimate—down from 8.8 in 2010). Growth is projected to continue until 2030, 50 years after implementing their one-child policy.

There are too many people on our planet, and some religions are still against contraceptives.

Humanity thinks it has the right to overpopulate, so we'll find out about sustainability when it's too late.

Noted. Too many children born is one side of the coin of overpopulation, increase of life expectancy is the other. While we may be able to evenly distribute the lowering birthrates, this may be cancelled out by an even distribution of high life-expectancies and a continuing increase. Birth control is perhaps much easier to address than everyone growing very old.

I am a non-practicing Catholic, and frankly I don't understand the Church's position in respect of the use of contraceptives, both for married couples and for those who is not. We are not breeding cows, when you give birth to a child you must be fully responsible and who is not should be helped to make the right decision. What sense does it make a hell of a child who dies of hunger before the second year of life??

Good article. An important issue that needs public discussion.

Thanks for posting.

If population growth in the next 37 years is the same as the last 37 years world population will be 9.85 billion by 2050.

Bearing in mind that 51% of the present world population are under 30....
