With 99% of its huge expanse frozen, Antarctica is a very, very valuable source of a fundamental resource. Of course, fresh water. 70% of all fresh water on the planet and 90% of all freshwater ice that exists, is in Antarctica.
In addition to the coldest place in the world, Antarctica is also one of the driest places on Earth. It is quite complex at first, that is, with all that ice ... however, the Dry Valleys of Antarctica have some of the most extreme deserts in the world.
