Here's something you don't see everyday: A polar bear swimming alongside beluga whales. This footage was captured by the Center's birds_and_mammals. Today is #InternationalPolarBearDay, and did you know the polar bear is the largest of the world's bear species and can reach heights up to 10 feet tall? Yet big and mighty as they are, two-thirds of the world's polar bears could be wiped out by 2050 if greenhouse gas-fueled global warming keeps melting their Arctic sea-ice habitat. So we're working to save these majestic animals from the deadly jaws of oil exploration and catastrophic climate change. And you can help. Visit the link in our bio to take action that will help protect these beloved white bears. #polarbears #polarbear #beluga #belugawhale #cetaceans #whales #wildlife #wildlifeconservation #marineconservation #endfossilfuels #climatechange #globalwarming
