The ice is the foundation of Arctic marine life, the ecosystem on which bears rely for every aspect of their lives. It is where they mate and raise their cubs. Sea ice is also an essential habitat for the polar bear’s primary food, ringed seals, as they pup and rest on the ice. Current knowledge shows that polar bears have some capacity to adjust to the warming Arctic, but the loss of sea-ice habitat may be happening too rapidly to allow for adaptation and there are no substitutes on land for the fat-rich seals on which the bears depend. Some of the best-studied polar bear populations are spending more time on land, like those in Manitoba, Ontario and southern Nunavut. Without sea ice and seals, polar bears are left to search for other food sources. This can lead them into communities, where garbage dumps, sled dog yards and human food storage offer easy pickings. Conflict between bears and people can follow......ed- it took millennia to evolve into magnificent creatures they are, but destined to be garbage collectors and maybe in the long run, even go extinct!
And a little bit of hope- What WWF-Canada is Doing. In Canada and across the Arctic, WWF supports polar bear studies that determine the number of bears, their health and the state of sea-ice habitat. This research includes satellite telemetry studies that help us understand their movements and habitat requirements. WWF is advocating for the protection of polar bear denning areas across the Arctic and working with Northern communities on effective polar bear co-management. Many Inuit believe that polar bears will adapt to a changing climate and have reported local increases in polar bear numbers in some areas of the Arctic. There is a need to use both Inuit knowledge and scientific information to plan for a healthy future for polar bears and people in the North. What is certain is that polar bears will face a difficult future without sea ice, which has been the foundation of their lives for hundreds of thousands of years. WWF is helping Northern communities live safely alongside the Arctic’s top predator. We work with communities to improve waste management, we fund training and salaries for locals to deter bears from villages and safeguard communities, and we raise awareness within communities on best practices for reducing conflict with polar bears. WWF’s efforts to protect the Last Ice Area, the area where sea ice will be most resilient, and what this will mean for polar bears.......read on https://wwf.ca/species/polar-bears/
