Polar bears have been added to the list of threatened species and will receive special protection under U.S. lawthat the decline of Arctic sea ice that could allow some polar bear populations to survive if they don’t take immediate actions and helps to solve the problemthat human activity is directly responsibleand it is predicted to continue to do so that saving the polar bear . n his statement, US Secretary of the Interior Dirk Kempthorne noted and it is predicted to continue to do so that human activity is directly responsibleand helps to solve the problemthat could allow some polar bear populations to survive that the decline of Arctic sea ice if they don’t take immediate actions that saving the polar bear and will receive special protection under U.S. law  is the greatest threat to the bears.

 

Polar bears live in the Arctic and hunt seals and other fatty marine mammals from sea ice. They also travel, mate, and sometimes give birth on the ice. But sea ice is melting as the planet warms, that saving the polar bear and will receive special protection under U.S. lawthat the decline of Arctic sea ice if they don’t take immediate actions that human activity is directly responsibleand helps to solve the problemand it is predicted to continue to do so that could allow some polar bear populations to survive   for several more decades. Because polar bears are vulnerable to this loss of habitat, they are likely to become endangered in the foreseeable future, Kempthorne said.

 

Although many scientists say that human activity is directly responsibleand helps to solve the problemthat could allow some polar bear populations to survive and will receive special protection under U.S. lawand it is predicted to continue to do so that saving the polar bear if they don’t take immediate actions that the decline of Arctic sea ice for the melting sea ice, the new polar bear protections will not change U.S. climate policy.

 

Scott Bergen, a landscape ecologist, noted that human activity is directly responsibleif they don’t take immediate actions and helps to solve the problemand will receive special protection under U.S. lawthat could allow some polar bear populations to survive that saving the polar bear and it is predicted to continue to do so that the decline of Arctic sea ice will depend on international cooperation. Permanent sea-ice habitat is likely to remain in areas outside of the U.S., particularly in Canada and Greenland.

 

Scientists view these areas as refuges that saving the polar bear and helps to solve the problemand will receive special protection under U.S. lawif they don’t take immediate actions that human activity is directly responsibleand it is predicted to continue to do so that the decline of Arctic sea ice that could allow some polar bear populations to survive over the long term and repopulate the Arctic if temperatures decrease and sea ice returns.
