Antarctica and the Southern Ocean may seem very far away from civilization, but they are at great risk of losing their unique qualities due to human activities. Warmer temperatures and human visitation are increasing the likelihood that invasive species can take up residence in the Antarctic, and potentially cause major changes. Two studies have found evidence of invasions both on land (from a midge) and at sea (from crabs). The remoteness of the Antarctic can no longer protect it from potentially destructive invaders.
