Difficult at best

After that, check out how close we are to collapse due to an interesting mix of self inflicted conditions that must be changed or we become toast if NASA's Goddard Space Flight Center's model of collapse proves to be true.

These factors can lead to collapse when they converge to generate two crucial social features: "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."

Modeling a range of different scenarios, Motesharri and his colleagues conclude that under conditions "closely reflecting the reality of the world today... we find that collapse is difficult to avoid." In the first of these scenarios, civilisation:

".... appears to be on a sustainable path for quite a long time, but even using an optimal depletion rate and starting with a very small number of Elites, the Elites eventually consume too much, resulting in a famine among Commoners that eventually causes the collapse of society. It is important to note that this Type-L collapse is due to an inequality-induced famine that causes a loss of workers, rather than a collapse of Nature."

Another scenario focuses on the role of continued resource exploitation, finding that "with a larger depletion rate, the decline of the Commoners occurs faster, while the Elites are still thriving, but eventually the Commoners collapse completely, followed by the Elites."

Overshoot, Greed, & GW, the troika of collapse, looms.
