“The Antarctic Peninsula has 40 percent less sea ice than it used to,” says University of Alabama’s Dr. James McClintock, adding that within 20 to 40 years it’s likely that no ice will form at all. While this might make it easier to set foot on the earth’s southernmost continent, it means there will be little to see in the way of wildlife. The ice serves as a nursery for krill, and if the krill population dips, so do the whale, Weddell seal, and Adélie penguin populations, all of which have already declined by a whopping 70 percent.

How to See It Now: New eco-ships such as Abercrombie & Kent’s Le Boreal are a low-impact way to explore this breathtaking wonderland.
