Okay, first, bignev -- Do you know why Argentina shipped it's women to the Antarctic to give birth? Have you ever SEEN an Argentine woman give birth? If you thought that scene in "Alien" was upsetting, you'd be puking your guts out for days with this one.
Everybody else, k_semier got it right. It's a moving land mass and any possible oil there (the spooky, tinfoil-on-head crowd notwithstanding) would be basically frozen solid. And even if was economically feasible to suck up that frozen black crude, it would have to be super-heated to travel through the thousands of feet of pipeline to stay liquified for barrelling. And frankly, I would not want to be standing on that platform when that well gets struck. You do remember what happens on a rig when a well is suddenly struck? Super-hot oil gushing down on your workers? Oh, yeah, no PR problems there...
