Jared_Diamond_on_why_societies_collapse

http://www.ted.com/talks/jared_diamond_on_why_societies_collapse.html

Why do societies fail? With lessons from the Norse of Iron Age Greenland, deforested Easter Island and present-day Montana, Jared Diamond talks about the signs that collapse is near, and how — if we see it in time — we can prevent it.

I will add to it : if societies are collapsing we must use this fact. Collapse is an immense release of energy, we can foster this energy to generate the “next society”. 

But I really think societies do not collapse, they transform. “Collapse” is a scholar adjective, transformation is what people do to survive, they adapt and this is continuously happening.
