That talking point died decades ago. We have a clear path to reducing our population. Well-off people with access to contraceptives don’t have high birth rates. We can roll back the human birth rate to sub-replacement levels and over time, reduce it.
There will be a problem with increasing population in 2250 or so, but we can cross that bridge when we come to it.
The moral thing to do is to ensure that all humans have access to clean water and food, contraceptives, and comfortable lives. The population will naturally go down and we can stabilize it over time.

The new estimated global peak population is 10.3B in 2084. But now, looking at the break down by region, you may be talking about North America? That graph looks wildly 3rd world… If you edit the graph to show US and Nigeria’s 2024 projections side by side it’s samepicture.jpg
