Simon Beard and Lauren Holt of the BBC have written an interesting article on what might pose the biggest threat to humanity.
Obviously climate change features, as do volcanoes, diseases, asteroid strikes, AI and similar.
However, I think they’ve forgotten a big one: overpopulation. We simply cannot support the population we have on the planet already and it it is increasing rapidly. When I say we cannot support the population, I mean we do not. Wealth spread evenly may well be able to do so but anyone who thinks that might ever happen is seriously overestimating human nature.
Even if that were to happen there would come a point, with current rates of population increase, where we’d just have too many people to feed and provide for.
We need a turnover of population of course. Put bluntly the old pay for the young until they leave home and then the young pay for the old when the young are working: pensions, medical care and such.
It’s not just the rising population but the rate at which it is rising has gone off the scale in the last few hundred years and, I believe, it’s unsustainable.
But I guess woe betide any government who tries to restrict breeding. The Chinese did it for a while but then again they’ve got a grip on their people that Western governments simply don’t have.
It is noticeable even between the 1970s and now. There are just far more people around and it just can’t go on unchecked.
