Only a species as fucked up and self-centered as humanity would equate it's own destruction with the end of the world. The planet will survive us, even if we nuke ourselves into oblivion. But we warned, Cumbrians have been messing with nuclear power longer than any other corner of the planet. I'm fairly convinced my cousin and a few of his mates, who've been at Sellafield since anyone can remember, would survive the so-called apolcalypse and if we're reliant on those head-bangers to re-populate the planet you could safely assume that movies like The Road have under-estimated the bestial nature of the survivors.
