As sea ice melts, some say walruses need better protection
ANCHORAGE, Alaska — Given a choice between giving birth on land or sea ice, Pacific walrus mothers most often choose ice.
Likewise, they prefer sea ice for molting, mating, nursing and resting between dives for food. Trouble is, as the century progresses, there’s going to be far less ice around.
How well walruses cope with less sea ice is at the heart of a legal fight over whether walruses should be listed as a threatened species, giving them an added protection against human encroachments.
The federal government in 2008 listed polar bears as a threatened species because of diminished sea ice brought on by climate warming. That year the Center for Biological Diversity petitioned to do the same for walruses.
However, the U.S. Fish and Wildlife Service concluded in October 2017 that walruses are adapting and no one has proven that they “need” sea ice.
