Dark news from the Poles. Research reveals that due to climate change, Polar bears may now face extinction at a pace much faster than previously imagined.
Polar bears depend on seals for food and seals upon the sea ice on which they mate and rest. Global warming is melting the ice, displacing the seals, and forcing the bears to travel farther and deplete more energy in order to find prey.
A three-year study conducted by the US Geological Survey and U.C. Santa Cruz, found that Arctic bears are now forced to search for food 1.6 times more than normal, leaving them exhausted by the shortage of calories.
In spite of the technology that allows us to track the bears, measure their activity, and assess their energy, without the solidarity to act decisively, their long-term survival is now highly doubtful.
