I never fails to puzzle me that a potential rising of the sea level of 50cm by 2050 resulting in 11% loss of land in Bangladesh is seen as a major threat, while at the same time its population growth that will roughly double in the same period is brushed off as nothing. Also, news tell us that in Syria climate change has resulted in food shortage in recent years. But having to feed twice as many people from the same…
A quick googling suggests that Bangladesh's current fertility rate is around 2 births per woman, which is actually just under replacement rate. The birth rate across the globe has been steadily on the decline for some time, there aren't many more places left where rapid doublings are still possible.
Climate change and the loss of species and such is one manifestation of overpopulation. Covid-19 could be viewed as another, in my opinion.
Obviously this is all rich coming from an American living in the suburbs (I don’t really see what my alternatives are), but I can’t help but think we can only sustain around a billion people without destroying the planet (speculation).
We live in a golden age of cheap energy and consumption. People get in gasoline powered cars and drive a mile down the road to get a snack. That’s impossible to maintain. Not only do we have overpopulation, but we built unsustainable cities, predicated on infinite cheap energy ($2.50 gas). Electric cars won’t fix this, although they’ll help.
