Polar bears.
The polar bear or the sea/ice bear are the world's largest land predators. They can be found in the Artic, the U.S. (Alaska), Canada, Russia, Denmark (Greenland), and Norway. The reason for the concern is global warming, which seems to be having its greatest impact so far on the polar regions, particularly the Arctic, the only place on the planet with polar bears. Warming trends of recent years have caused the ice pack that is so vital to the bears' survival to shrink, moving farther offshore and taking longer to form during the critical winter months when the bears load up on seals to get them through the summers. Of course, it's a bit premature to say these clever hunters that adapted to one of the harshest environments on Earth can't make yet another adaptation to a warmer habitat, but experts are doubtful. He is not alone in his concerns. Ian Stirling, an adjunct professor at the university who gained fame through his study of polar bears that have given the northern Canadian community of Churchill its identity, has documented a gradual decline in the well-being of those bears. They are leaner, smaller, and less able to find enough food to survive, according to Stirling. "The polar bear is in need of intensive care," said Brendan Cummings of the Center for Biological Diversity, "but with this lease sale the Bush administration is proposing to burn down the hospital." "MMS, by its own admission, has stated that oil spills are likely from its proposal to open up the Chukchi Sea to oil and gas development," said Mike Daulton, Audubon's Director of Conservation Policy. "That, combined with findings from the Army Corps of Engineers citing there are no effective methods for cleaning up oil spills in Arctic waters, seems enough reason to halt oil and gas activities until more is known about the migratory birds, marine life and unique conditions in this very harsh environment."
