The wait is over—at least for some of us. Polar Bear Week has arrived, but the polar bears of Canada’s Hudson Bay are still stuck on land.
Each fall, thousands of polar bears migrate to the bay to wait for sea ice to form, making up the largest concentration of these animals in the world. Polar Bear Week was created by Polar Bears International to celebrate this annual migration and draw attention to the sea ice that in recent years, has appeared later and later in the season. It’s also an opportunity to educate people about climate change and inspire them to work to reduce greenhouse gas emissions.

Amstrup has researched polar bears for 30 years, and is currently in Manitoba. He estimates that the bears there haven’t eaten in 150 days. “A lot of people don’t understand that polar bears depend on the sea ice for food,” he says….
