It’s called the frozen continent, and for millennia, Antarctica has remained frozen, not just in ice, but also in time. It is a place of pristine natural beauty, untouched by the tell-tale human construction, business, pollution, and warfare that crisscross every other continent on Earth. The place is just too cold for people most of the year. Only 1,000–5,000 people, all of them stationed at scientific study posts, live there during the year — but nobody lives there permanently.
