Here’s one:
quoted from https://www.smithsonianmag.com/science-nature/why-didnt-first-earth-days-predictions-come-true-its-complicated-180958820/
World population in 1970 was 3.7 billion, and is 8.0 billion now. Ehrlich predicted that the carrying capacity of the planet had been met, and yet the population has more than doubled without the mass starvation his model predicted.
Yeah, they also thought birth rate would stay steady. It's dropped like a rock instead.
It is true that agriculture got better in that time. It probably will again. There's no hard limit being suggested here, though.
