Yep, you read that title right (and I didn't make it up, that was from Reuters). Alien invaders to hit Antarctica but they won't be arriving via UFO.These aliens include seeds, spores, mites and mosses that are alien to the continent and have hitched a ride with scientists and tourists. Antarctica has been isolated until relatively recently, but the combination of global warming and more visitors has increased the number of alien species arriving and thriving on the continent.
The most damaging invaders so far have been reindeer and cats. Grass can also be a problem. As global warming creates warmer conditions, more and more outsiders may find the continent appealing.
