When Arctic ice melts, apex predators find themselves in your backyard

Alysa McCall: What to do when there's a polar bear in your backyard · 10:46 · Video: TED · Watch at the source

In short: As melting ice pushes polar bears onto land, humans and wildlife are facing increasingly frequent encounters. Biologist Alysa McCall explains how to navigate these dangerous interactions while protecting both communities and the animals.

Climate change is fundamentally altering polar bear behavior by forcing them away from their natural hunting grounds. These apex predators are increasingly turning to human junkyards for food, creating a new reality for northern towns that must balance safety with conservation.

McCall shares practical field lessons on managing these encounters. The goal is to develop creative strategies that keep people safe without harming the wildlife as our environments continue to shift.
