Polar City

A polar city is a proposed sustainable polar retreat designed to house human beings in the future, in the event that global warming causes the central and middle regions of the Earth to become uninhabitable for a long period of time. Although they have not been built yet, some futurists have been giving considerable thought to the concepts involved. High-population-density cities, to be built near the Arctic Rim and in Antarctica, New Zealand, Tasmania, and Patagonia, with sustainable energy and transportation infrastructure, will require substantial nearby agriculture. Boreal soils are largely poor in key nutrients like nitrogen and phosphorus, but nitrogen-fixing plants (such as the various alders) with the proper symbiotic microbes and mycorrhizal fungi can likely remedy such poverty without the need for petroleum-derived fertilizers. Regional probiotic soil improvement should perhaps rank high on any polar cities priority list. James Lovelock's notion of a widely distributed almanac of science knowledge and post-industrial survival skills also appears to have value.
