The polar regions are earth's least hospitable environment, yet people live in the Arctic regions. Modern urbanized life is possibly even there thanks to technology, but some (often tribal) communities still practice traditional methods, dependent on specific fauna, such as reindeer herding, dog sleds, hunting seals and collecting bird eggs. Some of those are even used by modern patrols in mineral-rich parts, e.g. in Greenland. The even harsher Antartic, were territorial claims are frozen, remains off-limits for exploitation, except controlled eco-friendly tourism and scientific research.
