While probably the safest place to be if World War III erupted, it ranks number ten on our list due to it's shear inhospitableness and inability to sustain a human presence for long. Antarctica is the fifth largest and the southernmost continent on Earth, but is 98% covered in ice, and on average is the coldest, driest, and windiest continent with the highest elevation. There are no permanent human residents, but anywhere from 1,000 to 5,000 people reside throughout the year at research stations scattered across the continent. The landscape on Antarctica that supports vegetation is considered a tundra, with organisms native to the landscape consisting of several types of algae, bacteria, fungi, plants, and Protista. You will also find certain animals including mites, nematodes, penguins, seals and tardigrades. The Antarctic Treaty signed in 1959, which prohibits military activities, mineral mining, and nuclear testing and disposal may help keep this place safe from WWIII.
