Why are polar bears endangered animals?
But because of ongoing and potential loss of their sea ice habitat resulting from climate change–the primary threat to polar bears Arctic-wide–polar bears were listed as a threatened species in the US under the Endangered Species Act in May 2008.
What are 5 facts about polar bears?
Top 10 facts about polar bears
- Polar bears are classified as marine mammals.

- They can swim constantly for days at a time.
- Less than 2% of polar bear hunts are successful.
- Scientists can extract polar bear DNA from just their footprints.
- They face more threats than climate change.
What is special about polar bears?
Polar bears have white fur so that they can camouflage into their environment. Their coat is so well camouflaged in Arctic environments that it can sometimes pass as a snow drift. Interestingly, the polar bear’s coat has no white pigment; in fact, a polar bear’s skin is black and its hairs are hollow.
How can we protect polar bears?
From fundraising for environmental charities to reducing your carbon footprint, learn how to save polar bears from extinction with three ideas.
- Volunteer your time.
- Help fight climate change.
- Raise money for an environmental charity.
- Repairing a sanctuary for polar bears.
- Fundraising for an arctic expedition.
How do polar bears survive?
Polar bears are well adapted to survive in the arctic climate. They have two layers of fur and fat for insulation, large paws to walk on the snow, and an excellent swimming ability. They can quickly build excess fat during winter which they can convert to energy to survive in the summer.
Why are polar bears endangered by climate change?
Polar bears have relatively high genetic diversity within the species and can disperse over very long distances, suggesting that they may have some capacity to adapt to the ongoing changes in the Arctic. However, their dependence on sea ice makes them highly vulnerable to a changing climate.
What the polar bear eat?
Polar bears feed primarily on ringed seals, but will also eat bearded seals, harp seals, hooded and harbor seals, when available. Larger prey species such as walrus, narwhal and beluga are occasionally hunted. Polar bears will readily scavenge on marine mammal carcasses.
What do polar bears eat for kids?
Polar bears are carnivores and are the top hunters in their Arctic habitat. They need a lot of fatty food to survive and their favorite snack is a seal. They also eat carcasses of animals like narwhals, walruses, whales, reindeer, and will eat kelp and even garbage, if necessary, to stay alive.
Why do polar bears need ice?
Polar bears need ice to capture their prey. They sit near the breathing holes and wait for a seal to pop up. Without sea ice, bears won’t be able to catch any seals. All other food that can be found by polar bears – fish, eggs, reindeer, and human garbage – is not so high in calories.
How does a polar bear protect itself?
Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice. The bear’s stark white coat provides camouflage in surrounding snow and ice. But under their fur, polar bears have black skin—the better to soak in the sun’s warming rays.
Where do polar bears sleep?
Like humans, polar bears sleep an average of seven to eight hours a day. They also frequently nap to conserve energy. The bears typically curl up and dig shallow pits in the snow, sleeping with their backs to the wind.
