For 50 years the birthrate per woman is <2. This hardly is a time scale where you can say people did not realise something. I don't see the trend you are describing at all. And this is not isolated. Afaik all developed countries have this trajectory. The solution to overpopulation seems rather simple then. Just make the world developed.
- bookofsand 5y agoConsider that Germany, given its technological headstart, has reached its carrying capacity a few decades ago. Lo and behold: Germany is slightly under 100% food self-sufficiency. Now throw in a 20k times increase in farming output... https://en.wikipedia.org/wiki/List_of_countries_by_food_self-sufficiency_rate https://en.wikipedia.org/wiki/List_of_countries_by_food_self...
- rowanG077 5y ago100% food self-sufficiency is a useless measure of whether a country has reached it's carrying capacity. As long as you can trivially import food it doesn't matter. Which is easily possible for Germany. Now take the Netherlands for example. It has a self-sufficiency ratio of 54%. By your logic it should have a MUCH lower birth rate as Germany. Yet the number is almost the same (Germany 1.540 vs Netherlands 1.570). This also doesn't square with the population growth due to immigration Germany has.
