What overpopulation?

Visit Jakarta

The kind you'd find in any place with a housing or food shortage, (or a job shortage if you are the sort of person who has #firstworldproblems) or really any other shortage where some public demand cannot be met by limited supply.

We don't see a lot of food shortages these days, but with climate change fucking with agriculture sufficiently, regular famines in the global south might make a comeback... Or might not, if population growth and degrowth projections solve that problem before crop yields are seriously impacted.
