The point is that more people in the same space create more demanding
conditions.

I recall reading some (sociological?) studies years ago done with lab
rats. As I recall, as their population density increased, the rate of
aberrant behavior increased much faster than did the population. Sort
of like the rats were being forced inside each others "fight or
flight" radius.

Wonder if that's why there seems to be so many two-legged vermin these
days.
