Can I suggest that you watch the BBC TV series '
The Ascent of Man '
http://www.youtube.com/watch?v=10fWml7Qu7Y (1 of 13 episodes) Yep, TV programs used to be like this before civilization ascended, peaked and declined in to X-Factor territory

!
Then watch a short documentary film about the presenter Dr Jacob Bronowski (his secret life) who died shortly after being interviewed by Michael Parkinson.
http://www.youtube.com/watch?v=BCfJstzPyZQIt may answer the question 'Is civilization artificial?'
It has also been suggested that the fall of the Roman Empire was due in no small part to their plumbing and the intellectual retardation toxic effects of the lead construction. Could there be something similar happening today?
