Overpopulation and starvation was another one from the 1970s—many “experts” believed mass starvation would be “the big story” worldwide by 2000.
The average person on the street has _much_ more common sense than any of the “experts”.
Instead, the “experts” are now saying the global population will likely peak and then begin to decline around the middle of this century, and that some countries. Some countries, like Italy, Japan, and China, will lose half their population or more by 2100, while the population of sub-Saharan Africa will triple. Populations in the developed world will have aged dramatically, and countries will be competing for immigrants to replace their vanishing workforce.
They’re probably wrong about most of this as well.
