Climate Change Force Polar Bears To Spend 4-Times Energy For Prey

Owing to climate change-induced glacier melting in the Arctic, the polar bears and narwhals now require four times as much energy to hunt for survival. A study published in the Journal of Experimental Biology discovered that sea-ice loss is forcing the cold-climate mammals to conserve themselves rigorously as killer whales have infiltrated the previously ice-locked ocean stretches. Reportedly, the diet alterations have forced the ‘sit-and-wait’ hunters to dive for prey amid the presence of whales.
