I am at the very centre of the great white continent, Antarctica. The South Pole is about half a mile away. For a thousand miles in all directions, there is nothing but ice. And, in the whole of this continent, which is about one-and-a-half times the size of the United States and larger than Europe, there is a year-round population of no more than 800 people. This is the loneliest and coldest place on Earth, the place that is most hostile to life. And yet, in one or two places, it is astonishingly rich.
