Replay: Why a Wildlife Biologist Traded Mice for the World's Most Dangerous Predator

18 minutes

When polar bear biologist Alysa McCall was growing up in Kamloops, British Columbia, watching black bears raid fruit trees outside her living room window, she never imagined she'd dedicate her life to their Arctic cousins. But sometimes the most profound career changes happen when you least expect them—like when a world-renowned scientist responds to your "what's the worst that could happen?" email with "Sure. Come over. See you in September."

McCall's journey from studying desert mice to becoming a polar bear researcher took her from the semi-arid landscapes of British Columbia to the frozen sea ice of Hudson Bay, where she learned that conservation isn't just about data—it's about connection, storytelling, and what she calls "big feelings."

Don't miss these unforgettable moments:

Growing up with black bears as backyard visitors (and banging pots to make them leave)

The "imposter syndrome" email that changed everything

Sleeping on a tundra buggy and mistaking a polar bear for a rock

Getting stranded alone on moving sea ice in -30°F weather

The mortifying moment of accidentally pointing a shotgun at your helicopter pilot (who later became her husband)

Holding her first polar bear cub and feeling the weight of conservation responsibility

Why emotion and storytelling are the key to saving Arctic habitat

The sobering reality: this polar bear population has dropped from 1,200 to just over 600 bears

The Science Behind the Story:

McCall explains why polar bear conservation requires a completely different approach than other wildlife protection—you can't fence sea ice or hire patrols to guard it. Saving polar bears means addressing global climate change, making it one of the most complex conservation challenges on Earth.
