Snirt writes "A new study (PDF) sponsored by NASA's Goddard Space Flight Center has highlighted the prospect that global industrial civilization could collapse in coming decades due to unsustainable resource exploitation and increasingly unequal wealth distribution. Noting that warnings of 'collapse' are often seen to be fringe or controversial, the study attempts to make sense of compelling historical data showing that 'the process of rise-and-collapse is actually a recurrent cycle found throughout history.' Cases of severe civilizational disruption due to 'precipitous collapse — often lasting centuries — have been quite common.' They say, 'Technological change can raise the efficiency of resource use, but it also tends to raise both per capita resource consumption and the scale of resource extraction, so that, absent policy effects, the increases in consumption often compensate for the increased efficiency of resource use.' After running simulations on the survivability of various types of civilizations, the researchers found that for the type most resembling ours, 'collapse is difficult to avoid.'"
