北極熊
Until the late 1940s, polar bears were hunted almost exclusively for subsistence by Inupiats and dogs teams, though from the late 1940s until 1972, sport hunting by others took place. The 1959 Statehood Act set up a program for polar bear management, and further conservation efforts, including the 1972 Marine Mammal Protection Act, have limited polar bear hunts. Polar bear populations may be threatened by oil development and global warming. Only about 4700 polar bears are known to inhabit Alaska.
