Almost all of us have a biological need to procreate.
This exceeds any thought of consequences.
I doubt people ever think of over-population as they set about generating offspring.
But the world is just so big.
There is a limit to the number of people it can support.

Fortunately, there are natural occurrences which limit population.
Lack of food, and disease, are two examples.
However, we do our very best to defeat these.
So the population grows and ages.
And the world is full of older, less productive, persons.

But it won't go on forever.
Eventually, there must be a major contraction in numbers.
The swathe of humans will shrink.
Balance will be restored.
Whether it is the mentally or the physically fit who then predominate will be significant?

I agree that population is a key problem- but the authors of this article appear to be all "Eco-Socialists" perhaps Communists- so we should be careful "not to" follow their suggestions for the solution.

Patrick Deneen writes in his book "Why Liberalism Failed"- because it was based on the fallacious assumption of the unlimited bounty of the Earth.

Population is mainly a problem in non-western nations. The west consumes more resources because we are higher in the hierarchy of nations- linked to production and value. There will always be dominants in the hierarchy pray that they are at least as sane as in stable times of history. The wider the base of the pyramid the higher it is.

Write to you MP. Write to Ministers.

An alternative to actually doing something and writing to your MP and Ministers - just shut up. A handful of people ruminating here are not go to change anything.

The wider the base of the pyramid the higher it is.
Canem Malum,
Great analogy ! And, when one considers the makers vs the takers situation it’s even more poignant in the inverted example !
