ナショナルジオグラフィックさんのインスタグラム動画 - (ナショナルジオグラフィックInstagram)「Video by @bertiegregory I heard rumors about a pack of wolves that takes on polar bears. Fast-forward two years, and I was on my way to the Canadian subarctic with a commission from National Geographic to film that behavior. During the long journey to get to the location, I was nervous that I might have overpromised. However, the rumors turned out to be true. Had I come across the situation in this video before, a polar bear nervously watching wolves, I would have assumed the bear had nothing to be concerned about. We now know this pack of wolves can pose a very real threat, especially with young or injured polar bears.
