The other day I was asked to do an interview for a South Korean radio station about the declining-population “crisis”.
Therein lies the rub — there is no crisis.
While I think the interview went well (you can listen to it here), I didn’t have ample time to flesh out my arguments; I’ve decided to put them down in more detail here.

Probably the most important aspect that I didn’t even get a chance to cover is that globally, our economic system is essentially broken because we are forced to exist inside a paradigm that erroneously assumes Earth’s resources are infinite. They are not, as the global ecological footprint clearly shows.
To slow and perhaps even reverse climate change, as well as mitigate the extinction crisis underway, we are obliged to reduce consumption globally. Shrinking human populations will contribute to that goal (provided we simultaneously reduce per-capita consumption).
But that argument, no matter how defensible, is still not even remotely appreciated by most people. It is the aim of only a minority, most of whom have very little political power to engender change.
The oft-touted ‘crisis‘ of ageing populations is founded on the erroneous notion that it will lead to economic crises for the affected countries. Indeed, countries like South Korea and Japan have declining populations, others like Italy are stable and will be declining soon, and others like Australia are only growing because of net immigration.
The reason for the hyped-up panic generally comes down to the overly simplistic ‘dependency ratio‘, which has several different forms but generally compares the number of people in the labour force against those who have retired from it. The idea here is that once the number of people no longer in the labour force exceeds the number of those in the labour force, the latter can no longer support the entirety of the former.
This simplistic 1:1 relationship essentially assumes that you need one person working to support one retired person. Errrh. Right. Let’s look at this in more detail.

The very worn slur of “neo-Malthusian”
7 09 2021After the rather astounding response to our Ghastly Future paper published in January this year (> 443,000 views and counting; 61 citations and counting), we received a Commentary that was rather critical of our article.
We have finally published a Response to the Commentary, which is now available online (accepted version) in Frontiers in Conservation Science. Given that it is published under a Creative Commons Attribution License (CC BY), I can repost the Response here:
In their comment on our paper Underestimating the challenges of avoiding a ghastly future, Bluwstein et al.2 attempt to contravene our exposé of the enormous challenges facing the entire human population from a rapidly degrading global environment. While we broadly agree with the need for multi-disciplinary solutions, and we worry deeply about the inequality of those who pay the costs of biodiversity loss and ecological collapse, we feel obligated to correct misconceptions and incorrect statements that Bluwstein et al.2 made about our original article.
After incorrectly assuming that our message implied the existence of “one science” and a “united scientific community”, the final paragraph of their comment contradicts their own charge by calling for the scientific community to “… stand in solidarity”. Of course, there is no “one science” — we never made such a claim. Science is by its nature necessarily untidy because it is a bottom-up process driven by different individuals, cultures, perspectives, and goals. But it is solid at the core. Scientific confluence is reached by curiosity, rigorous testing of assumptions, and search for contradictions, leading to many — sometimes counter-intuitive or even conflicting — insights about how the world works. There is no one body of scientific knowledge, even though there is good chance that disagreements are eventually resolved by updated, better evidence, although perhaps too slowly. That was, in fact, a main message of our original article — that obligatory specialisation of disparate scientific fields, embedded within a highly unequal and complex socio-cultural-economic framework, reduces the capacity of society to appreciate, measure, and potentially counter the complexity of its interacting existential challenges. We agree that scientists play a role in political struggles, but we never claimed, as Bluwstein et al.2 contended, that such struggles can be “… reduced to science-led processes of positive change”. Indeed, this is exactly the reason our paper emphasized the political impotence surrounding the required responses. We obviously recognize the essential role social scientists play in creating solutions to avoid a ghastly future. Science can only provide the best available evidence that individuals and policymakers can elect to use to inform their decisions.
We certainly recognise that there is no single policy or polity capable of addressing compounding and mounting problems, and we agree that that there is no “universal understanding of the intertwined socio-ecological challenges we face”. Bluwstein et al.2 claimed that we had suggested scientific messaging alone can “… adequately communicate to the public how socio-ecological crises should be addressed”. We did not state or imply such ideas of unilateral scientific power anywhere in our article. Indeed, the point of framing our message as pertaining to a complex adaptive system means that we cannot, and should not, work towards a single goal. Instead, humanity will be more successful tackling challenges simultaneously and from multiple perspectives, by exploiting manifold institutions, technologies, approaches, and governances to match the complexity of the predicament we are attempting to resolve.
