What caught my eye this week.

For some people, news that the population time bomb may be spluttering gives hope we can halt – or even reverse – environmental calamity.

For others, it’s the harbinger of a demographic shift that will hole portfolios below the line and lead to a great deflation.

Given the huge numbers involved – billions of lives, trillions of dollars – there’s naturally some debate about exactly when Facebook will have to start reporting shrinking user numbers.

This graph from Bloomberg plots several schools of thought:

(Click to enlarge the population projection!)

I argue quite often with friends – some whom I’d never expect to have such a debate with – about the desirability of a radical reduction in the human population.

I’m all for it. Presuming it happens slowly, and without plague, nuclear bombs, or grey goo.

But many friends are perturbed by the idea.

Some are parents who tell me their kids will pay my pension, and theirs. A handful are religious. But unexpected friends fear it, too. Determinedly childless singletons, and one who otherwise seems a confirmed misanthrope.

Our two million-year-old family tree was populated by those with genes that willed them to spread far and wide (and trimmed the likes of me) so I shouldn’t be surprised.

I suspect it’s a also cultural thing. The very idea is alien.

I have daydreams of half a billion people living in beautiful megalopolises, serviced by robots, surrounded by wilderness, and connected by Hyperloops and electric helicopters.

They see a lack of consumers. And, I suspect – though it’s unspoken – a lack of Europeans.

Bye bye birdies

Whether a plateauing population can save the planet is as debatable as whether capitalism could withstand it.

From the Bloomberg piece:

Let’s assume that their lowest population projection is correct, and global population will peak in 2045. That’s still a quarter-century from now, and population wouldn’t return to current levels until the 2090s — more than enough time for us to drive hundreds of thousands of plant and animal species extinct and perhaps boost global average temperatures enough to bring polar-ice-cap-melting chaos.

The “rapid development” scenario behind that population forecast also requires that poorer countries, well, develop more rapidly, which in the past has meant rising per-person environmental stress.

If India’s population were to stop growing tomorrow but its per-capita carbon emissions kept rising to current U.S. levels (a nearly tenfold increase), that would lead to a 59 percent rise in global carbon emissions, all else being equal.

Before anyone types it, yes I’ve read stuff by Hans Rosling and Bjorn Lomberg. The former is great but very anthrocentric. The latter was weak on biodiversity, as I recall.

Personally, about the only reason I have for not wishing I was 20 years younger – apart from genuine gratitude at the life I’ve had along the way – is the mess we’re making of the planet.

(Oh I know, I know, you wouldn’t change a thing… but think of the compound interest!)

And finally…

“I’d tell men and women in their mid-twenties not to settle for a job or a profession or even a career. Seek a calling. Even if you don’t know what that means, seek it. If you’re following your calling, the fatigue will be easier to bear, the disappointments will be fuel, the highs will be like nothing you’ve ever felt.”
– Phil Knight, Shoe Dog: A memoir by the creator of Nike
