Three environmental groups are suing the U.S. government to force consideration
of whether polar bears are a threatened species, saying rising global temperatures
threaten to kill off the Arctic predators.
The suit, filed in U.S. District Court in San Francisco on Thursday, asks the
Interior Department to make an initial ruling on a petition to bestow the broad
federal protection of the Endangered Species Act upon polar bears by designating
them as "threatened."
An "endangered" species is one that is in danger of extinction throughout
all or a significant portion of its range, according to the U.S. Fish and Wildlife
Service's Web site (http://www.fws.gov). A "threatened" species is
likely to become endangered in the foreseeable future, according to the agency.
The lawsuit was filed by the Center for Biological Diversity, the Natural Resources
Defense Council and Greenpeace, which say the department should have ruled on
its petition within 90 days of its filing in February.
If the suit is successful, there will be two more steps, each of which can
take up to a year, before polar bears could be officially listed as threatened.
The groups argue that rising global temperatures endangers polar bears by melting
the ice floes on which the giant predators prowl and hunt.
Kassie Siegel, climate director for the Center for Biological Diversity, said
the group's petition on polar bears was bolstered by a report this week from
the U.S. Minerals Management Service detailing the deaths of four polar bears
that drowned in September 2004.
"As global warming continues, more bears are going to die. This is very
predictable, it's common sense," Siegel said. "Their habitat is sea
ice. They don't hunt from land, they don't hunt from water. They can't survive
if their habitat disappears."
A spokesman for the Interior Department did not return a call seeking comment.
