With the progressive thinning of Ice on Hudson Bay and the rest of the polar regions, the Polar Bears future survival is most uncertain.
In Western Hudson Bay the polar bears spend about 7 to 8 months a year on the Sea Ice in pursuit of its primary prey, "Ringed Seal" and to a lesser extent, "Bearded Seal". Polar Bears rely on the sea-ice to hunt the seals by waiting around open leads in the ice where seals come to the surface for air, the bears then pounce on the seals with deadly consequences then stripping the seals of its nutritious blubber and other high energy proteins. The polar bears also hunt the young seal pups while still in their lair and on the ice, shortly after the seals are born.
The Polar Bear is primarily carnivorous and is classified as a carnivore, however it is actually omnivorous. Polar Bears eat amongst other things: seals, caribou, young polar bear cubs, goslings, goose eggs, lemmings and other small rodents, berries, kelp, small crustaceans, willow buds, Sea-lyme grass & other sedges, to name a few.
With rising polar temperatures it is conceivable the overall energy requirements of the Polar Bear may increase to some extent as the bears will need to search for alternative food sources which will be required to supplement its decline in seal diet. While scientists continue to monitor the polar bears health there is already indications that the global population of polar bears will be adversely affected by global climate change. Many polar bears and humans may not be unable to adapt successfully and in synchronization with both the natural and man made consequences of global climate change. |
