Environment:Ice Worlds: Life at the Edge

At the top of the world, it is the Arctic, at the bottom, the Antarctic, two hostile ice worlds shaped by bitter cold. Despite their harshness, the polar regions are home to abundance of life. The Antarctic has penguins, the Arctic, polar bears. Why did they have such different animals? And what strategies do these animals have that enable them to survive in the harshest environment on earth? These intriguing questions draw biologists to these difficult places as they strive to unravel the mysteries of life at the edge.
