Polar bears are absolutely crucial to the sustainability of the Arctic marine ecosystem. The majority of the world's polar bears live in Canada and they're currently at high risk of becoming endangered due to climate change. Biologists estimate that there are only around less than 25,000 polar bears left living in the wild, and 60% - or, nearly two-thirds - of them call Canada home, says the Toronto Zoo.\nREAD ALSO: The Government Is Committing $175 Million Dollars Into Protecting Canada's Lands And Oceans\nWith International Polar Bear Day coming up on February 27th, the Toronto Zoo has taken time today to share some important facts about polar bears and their necessary species survival.\n"Zoo biologists and researchers work closely with their wildlife biologist colleagues in the field with valuable learning and studies that can be applied to polar bear conservation in the wild," said the Toronto Zoo in a tweet.\nREAD ALSO: Canada Is Seriously Committing $150 Million Dollars Into The Vegan Food Industry\n"This is very important as biologists estimate there are only approximately 20,000 to 25,000 polar bears in the wild with approximately 60% of those living in Canada".\nThe Toronto Zoo also shared a video of a behind-the-scenes session where workers care for polar bear Hudson on their Twitter.

"There is a high estimated risk of future decline due to climate change and data deficiency," warns the WWF on their website.\nREAD ALSO: Canada Was Named One Of The Most Beautiful Countries In The Entire World\nPolar bears are currently categorized as a vulnerable species, but that could soon change for the worse. "Because of ongoing and potential loss of their sea ice habitat resulting from climate change, polar bears were listed as a threatened species in the US under the Endangered Species Act in May 2008," says the WWF.\nView this post on Instagram Over a decade ago, we decided polar bears needed a day of their own➖both to celebrate them and raise awareness about the threats they face. We chose February 27th for International Polar Bear Day because it's frigid in the Arctic at that time of year, and polar bears thrive in these frosty conditions! . International Polar Bear Day is now celebrated around the world 🙌🌏🌍🌎🙌! Join this global event to draw attention to the challenges polar bears face in a warming Arctic and how we can each help.

"At least two-thirds of the world’s polar bears live in Canadian territory, giving Canadians a special relationship with and responsibility for these bears," says the WWF on their website.\nThe survival of the polar bear species affects us all and is crucial for sustainability. "The survival and the protection of the polar bear habitat are urgent issues for WWF," says the international non-governmental organization.\nView this post on Instagram In late January, we're thinking about mother polar bears deep in their snuggly dens! Most moms choose den sites in snowdrifts along mountain slopes or hills near the shore. Some dig their dens in snowdrifts on the sea ice. Cubs are most often born in December, but the family doesn't emerge from the maternal den until March or April. . When born, cubs are about the size of a stick of butter! Polar bear moms have the fattiest milk found on land at ~31% fat. This calorie rich diet helps the cubs grow ~10x their birth weight in just a few months. 💪🥛 . When the cubs are big enough, mom will break out of the den, and the family will prepare for their journey to the sea ice. 🐾🐾🐾🌊❄️ . . . . #polarbears #polarbear #bearcub #polarbearcub #momsandcubs #wildlifefacts #arcticwildlife #arcticconservation #arctic #saveourseaice A post shared by Polar Bears International (@polarbearsinternational) on Jan 29, 2019 at 8:23am PST\nTo help contribute to efforts to save the polar bears, there are several different ways you can get involved. For starters, you can do incorporate simple habits in your everyday life to reduce your impact on climate change, which is what is causing polar bears to move towards becoming endangered.\nEasy, everyday actions such as eating vegetarian or vegan foods, eating more often locally sourced foods, taking the bus or walking instead of driving more often, reducing your plastic consumption by using less plastic bottles or buying less plastic packaging, and more can add up and can help reduce your carbon footprint.\n@polarbearsinternationalembedded via\nThere are also several initiatives you can take part in that directly help save the polar bears. For instance, Polar Bears International has various initiatives and to find out more, you can visit their website.\nBy helping reduce your impact on climate change, you're helping to contribute to saving polar bears and their habitats.
