as civilization collapses, we're going to see horrific scarcities, creating massive personal and collective stresses that will break both individuals (to the point of suicide, terrorism and murder) and nations (to the point of insurrection, civil war, and anarchy -- a hundred Afghanistans). We're going to see dreadful pandemic diseases and poverty and famine that will be utterly shattering, like the abject horror the world witnessed during the Irish potato famine where millions simply sat around, hopeless and increasingly gaunt, until they died an agonizing death alongside those they loved and couldn't save. We're going to see the kind of spiritual vacuum and decay that is eating Russia and the former Soviet republics alive today, with population and life expectancy plummeting, drug addiction at epidemic levels, and crime and gang violence out of control. It is nature's last and most reluctant way of restoring to sustainable populations species whose numbers and voraciousness have run amok.
Or, as an alternative, we could be sensible and tackle the problems facing us - climate change, deforestation, overfishing, overpopulation, peak oil, peak water, poverty - seriously, not with political posturing and soundbites, and maybe come out the other side.
