Offshore from Alaska's North Slope, Arctic sea ice is a crucial part of the habitat for marine wildlife including polar bears, walruses and seals. But in a region where climate change is occurring at twice the rate of the rest of the planet, that wildlife is in jeopardy. Melting ice shrinks the hunting and resting grounds of marine mammals and encourages industrial development in the form of offshore oil drilling. It also threatens the subsistence lifestyle of Alaska's indigenous people. To learn more, visit http://www.pewenvironment.org/arctic.
