Bob,

I disagree that the UK is manifestly in population overshoot. Bear in mind that it has a temperate climate, and huge areas of fertile farmland that have been exploited largely sustainably for hundreds/thousands of years. Obviously the future is not energy-rich, probably not economically rich, but probably one of the better places on earth to survive in.

... Unless the icecaps melt of course!

Peak oil is not scary; global warming is, especially given the prospects for another Atlantis. All these decreases in energy production yet another good reason to get radical about cutting energy consumption.
