Humans have notoriously short memories. Perhaps that's why it is inherent in Human Nature not to do anything 'until after the horse has bolted'. That is what has happened repeatedly in the past.
If history is anything to go by: Both economic and population growth are checked by economic, political and environmental disasters. This seems to cause a natural balancing effect. It happens repeatedly over time: Economic collapse, wars, earthquakes, tsunamis and pandemics, to name a few; regularly check the rise of populations.
We have been 'steaming along' as of late. Looking at history again: A 'steaming along' seems always to be followed by a 'checking' of about the same magnitude. Perhaps it is inevitable. But one thing is for sure: SOMETHING will happen: Humans have never been in control. But we keep trying. Because that's all we can do. In the end, we all die, anyway.

LadyAussieAlone,

"In the end, we all die anyway".

Once Kanck as titular head of the Sustainable Population Lobby is rolled by either the Greens, the Weathermen, poor developing black people or unmedicated schizophrenics (who think she is talking about them), then I will nominate you as President for Life.

You're my kind of lady.
