The world's most southerly polar bears may be the first animal to disappear as a result of climate change. But polar bears are as tough as they get and the element of surprise is one of their greatest tools. The polar bears aren't giving in without a fight... for their lives. And later bear 911. North Vancouver Canada is a large suburb on the edge of civilization. It is not uncommon to see bears roaming past the BMW's in the driveways. Here in North Vancouver 911 gets you fire police ambulance and bear cops! Xtremely Wild spends a week chasing bears around the North Shore up trees into swimming pools and hopefully into a better life as we relocate North Van's worst offenders.
