Polar bears are land predators known to make the ice and sea of the Arctic a primary habitat. Not only are they well equipped for survival in a harsh environment, but they are also known to have paws adapted for walking on the sea ice and swimming in the sea.
They rely solely on the Arctic part of the world to live, travel and hunt ringed seals that live at the ice edge, mate and rest.
Over the years, these beautiful creatures are beginning to lose themselves due to the rapidly increasing rate of sea ice loss. Not only has this sea ice loss caused them to lose their vital habitat, but it has also affected their ability to find food for survival.
Fate Of Polar Bears Is Mainly Dependent On Climate Change
It has been stated that the subsequent fate of polar bears is mainly dependent on climate change. The conservation status studies of the polar bear reveal that continuous ice loss, which is a result of the rising temperature means little or no access to seals.
The studies further revealed that this rising temperature has continued to hinder reproduction, nourishment of bear cubs and unstable maternity den.
These, in turn, have resulted in the depletion of the body condition and average weight of older bears.For new polar bear cubs, most do not survive and few cubs that do tend to be smaller in size.
Hence, Scientists have stated that polar bears will face a bleak future if the temperature keeps rising.
The report in Baffin Bay also concludes that “It is reasonable to predict further changes in this subpopulation including an ultimate decline in abundance.”
Polar Bears Result To Cannibalism During Food Scarcity
According to the Russian Researcher at Moscow’s Severtsov Institute of Problems of Ecology and Evolution, Mordvintsev, “cases of cannibalism among polar bears are a long-established fact but we are worried that such cases used to be found rarely while now they are recorded quite often.”
Although cannibalism is not unknown amongst sea bears, climate change melting Arctic ice as well as fossil fuel extraction on their habitat has led to food scarcity thus causing polar bears to resort to eating each other.
Although they are mainly known to eat seal fat, they have now resulted in eating just anything as a result of food scarcity; whether it’s their kind or not.
Ilya Mordvintsev has also stated that sea bear cannibalism is now distressingly rampant unlike a few years ago where it was rarely frequent.
