Already threatened by climate change and shrinking sea ice, the polar bear also contends with plastic pollution and pesticides in its environment that are harming the endocrine systems and reproductive systems of these mammals. This is a day we can focus on the challenges polar bears face in a warming Arctic, and how we can help.
For example, heating and cooling account for roughly half the energy consumption in an average home. The Thermostat Challenge is part of Polar Bear International's Save Our Sea Ice (SOS) campaign, a series of celebrations centered around action on climate change. It begins each year on International Polar Bear Day, February 27th, and continues through Polar Bear Week in the fall—although you can take the challenges at any time.
