That was going on even in the 1960s.
I remember being taught in elementary and middle school about the coming Malthusian Crisis of over-population. The Population Bomb was The Crisis back then.
Then came global cooling, we were headed for a new Ice Age. What would your arcology look like?
When I was in HS, The Crisis was nuclear winter.
I was out of college by the time Global Warming became The Crisis.
Now The Crisis is ‘Anthropogenic Global Climate Disruption’ so they can blame everything on it.
None of that until Senior year when science teach said we were headed into a mini Ice Age but not what it would cause.
