Fascinating NASA Study

Report today of a study by NASA on civilizations.

NASA claims: Dozens of advanced ancient civilizations collapsed before us

I know, right? I thought they just studied the stars.

Anyway, they studied why civilizations collapse, what takes them down. You'll find the entire study at the link below.

The study came to the conclusion there are two key social features that contributed to the collapse of every single advanced civilization from the past:

“...the stretching of resources due to the strain placed on the ecological carrying capacity”;

and “the economic stratification of society into Elites [rich] and Masses (or “Commoners”) [poor]”

These social phenomena have played “a central role in the character or in the process of the collapse,” in all such cases over “the last five thousand years.”

So I ask you, does any of this sound familiar, folks?
