Celebrating International Polar Bear Day

Polar bears are iconic animals, known for their incredible ability to survive in one of the harshest environments on Earth. These marine mammals are the most carnivorous member of the bear family, with a diet consisting primarily of seals. They have a thick layer of fat and waterproof fur, providing insulation in the cold Arctic climate in which they live.

Sea ice is imperative for polar bear survival; they spend the majority of their lives on the ice, relying on it to find a mate, build a den and hunt for seals. In the last 30 years, scientists have seen a dramatic shift in ice within the Arctic Ocean. The amount of “old ice” – ice that stays throughout the summer – is significantly smaller than what it was 30 years ago. The seasonal sea ice is forming later in the year – and melting earlier – directly impacting polar bears’ ability to hunt. As a result, many polar bears aren’t able to build up the fat reserves they need for the summer when food sources aren’t plentiful, and they starve to death.

We know the climate is changing. As humans, we are using fossil fuels such as coal and gas to drive cars and use electricity. These fossil fuels release carbon dioxide into the atmosphere, which builds up and creates a blanket effect around the Earth, trapping in heat that would otherwise escape. This trapped heat is causing global climate change and is impacting many species, including polar bears.

On February 26 and 27, the Detroit Zoo will join others around the world in highlighting the challenges that polar bears are facing in the wild. International Polar Bear Day celebrates these majestic creatures while also encouraging the community to not only better understand the impact we have on the environment, but to join us in taking positive action that will help protect vulnerable species.

Each one of us has the power to make a difference. We can change our daily behaviors and use less energy by seasonally adjusting our thermostats, riding our bikes, carpooling with friends or turning off the lights. We can also scale these actions up to our schools or workplaces by encouraging others to join us in this endeavor. Celebrating International Polar Bear Day is a great reason to start, or to take things to the next level.

Our International Polar Bear Day will take place on February 26 and 27 from 11 a.m. to 3 p.m. The events will include zookeeper talks, educational activities and visits with the Zoo’s polar bear mascot. Talini and Nuka, the two polar bears who reside at the Zoo, will receive their usual treats at scheduled times (11:30 a.m., 1 p.m. and 2:30 p.m.) so guests can watch the bears enjoy them. This is not only a great time to visit the Zoo and the more than 2,000 animals living within our 125 acres, but it’s also a chance to learn more about how we can work together to save wildlife and wild places.
