Is the extraordinary polar bear going the same way as the dodo? A large flightless bird, the dodo was last seen in the 1600s, when it was most likely clubbed on its island home by protein-starved sailors looking for some meat for their cooking pot.
While our generation is not likely to be guilty of eating the last wild polar bear, we are contributing to the rapid decline of the iconic species because of the industrial emissions we have been pumping into the atmosphere since the Industrial Revolution (read the explanation of this further along this post).
Take a moment this International Polar Bear Day (February 27, #polarbearday) to reflect on this incredible species and how we stand to lose it in the wild by the end of this century.
Ursus maritimus is Threatened wherever it is found, says the U.S. Fish and Wildlife Service (FWS). According to FWS, 19 populations of polar bears are distributed in Alaska, Canada, Greenland, Norway, and Russia. The worldwide population is estimated to be 22,000-25,000 bears. But while these numbers remain relatively stable, FWS says, “climate change, contamination of the Arctic environment, potential over-harvest, and increasing human development in polar bear habitat pose conservation challenges for polar bears.”
Whereas in earlier times the main threat to polar bears was hunting, today the primary conservation concern for polar bears is loss of their sea-ice habitat and reduced access to their primary prey, due to climate change, says Polar Bears International. “Without action on climate change, scientists predict we could lose wild polar bears by 2100. Two-thirds could be gone by 2050,”says PBI. The nonprofit’s mission is to conserve polar bears and the sea ice they depend on.

What can we do?
Find out more about polar bears and the risk to their survival by browsing the links below. Consider how climate change is being effected by how we use our planet in unsustainable ways. Decide for ourselves what we can do to help reduce our impact on our planet through educating ourselves and others, supporting appropriate causes, and making the best decisions for how we conduct our lives.
