Where will the polar bears go as the Arctic ice melts under their feet

The Arctic regions are home to a variety of wildlife, including polar bears (Ursus maritimus). Polar bears are generally solitary animals. At first glance, more than white, are cream-colored. In fact, the outer coat is hollow and translucent and perfectly fulfills its function of transmitting the sun’s heat to the base of the hair, where the skin is black.

 

The polar bear is the top predator of the Arctic marine ecosystem. It feeds mainly on seals, but also includes walruses, and belugas in their diet. As one can see, it also overwhelms with its enormous size. So, as prevention, when people are in the presence of these animals, researchers are equipped with live-fire weapons, although the purpose is not having to use the weapons ever, which is very easy if you do not bother the bear.

 

Some studies suggest that almost two-thirds of these bears will disappear by 2050 if the decline in ice cover continues at current rates. “Reducing the ice is affecting the ability of the bears to survive,” explains Robert Buchnan, president of Polar Bears International. “The bears depend on sea ice as a platform from which to hunt seals.”

 

Of the 19 populations of polar bears in the world, 13 are permanent residents in Canada. “If the ice disappears, said Dr. Steven C. Amstrup, the bears will disappear with it. I’ve Lost more than a million square miles of sea ice, which is equivalent to an area the size of Alaska, Texas and Washington.”

    Yep, it’s gonna be tough, especially since the population has quintupled since the 1960′s. All that extra stress on the population caused by global warming has caused them to, to, … hey, wait a second…

    IIRC, genetic drift analysis indicates that ursus maritimus survived very nicely thank you the last time the Great White North wasn’t so, well, white.

    Polar bears withing recorded history, used to range down to the Gulf of St Lawrence as did their prey, the Baluga whale and vast numbers of various species of seal. The problem is not so much the melting of the ice but the fact that we have destroyed their habitat and the animals they depend on in order to light our oil lamps and lubricate our machinery. With the melting of the ice, the polar bears would manage perfectly well but we will destroy the Arctic as we go after fisheries and mineral oil resources so they will go extinct.

    Ice is good for the polar bear,
    A platform from which it can hunt.
    Sea ice was and now is not there.
    Greenhouse gases get the blame brunt.
    Maybe humans could change their ways
    Of burning fossil fuels a lot,
    And make Earth go to cooler days.
    Maybe humans can, maybe not.
    The ice ages have come and gone,
    So ice most likely will return,
    For humans then to fret upon,
    As more fossil fuels, humans burn.

    When all Earth gets covered in ice,
    Will polar bears think that is nice?
