I remember some class or textbook reading that told us that if you keep crowding rats in a cage, at some point, they begin exhibiting anti-social, violent behavior.
Got me thinking -- when I was a kid in the 1950's, world population was about 2,556,000,000. World population today is around 7,000,000,000
Quite a population explosion.
Our resources and arable land are finite. Climate change is reducing our natural resources.
There also seems to be sense of futility and hopelessness that our world is on the downslope and things will not improve.
Have you seen any evidence of humans exhibiting anti-social or violent behavior of late (said with tongue firmly n cheek).
How much of this, do you suppose, is caused the press of population??
