Sound Familiar?

A NASA funded research paper says that our unsustainable consumption of resources, our excessively large population and the increasing levels of inequality will lead to “irreversible collapse.” This is not exactly a fringe group of doomster conspiracy nuts. The authors cite compelling historical data showing that "precipitous collapse - often lasting centuries - have been quite common” throughout history. The main factors leading to civilizational collapse have been excess population, changing climate, high levels of economic stratification, water shortages, agricultural failure and failing energy sources. Sound familiar?
