While many people believe that polar bears are in danger because of global warming, it might surprise them to learn that polar bear numbers have actually quadrupled in recent decades. Such news is no surprise to residents of Churchill, Manitoba, however, who are experiencing an invasion of polar bears in their town. According to reports, polar bears are commonly seen walking down Churchill’s main street, and people have learned to leave their cars unlocked so they can quickly duck inside if one approaches. It’s gotten so bad, in fact, that dogs are routinely being eaten, a polar bear hotline has been created, and kids cannot go out trick or treating without a parent packing a shotgun for protection.
