案例简介：@ bertiegregory的视频一只雄性北极熊在加拿大哈德逊湾西海岸小睡后摇雪。这些巨大的熊可以超过800千克/1800磅。这个特殊的男性并不着急。他在水边等待着大冻结: 这是一年一度的活动，当海洋变成坚如磐石的路径时。这种冰使他可以猎杀他的主要猎物，环海豹。我们的气候变暖每年将大冻结的到来推迟了大约一天。这意味着这只熊失去了前几代人赖以生存的一个月的狩猎。跟随 @ bertiegregory进行更多野生动物冒险。# 野生动物 # 雪 # 加拿大 # 冷冻

案例简介：Video by @bertiegregory A male polar bear shakes off snow after a nap on the west coast of the Hudson Bay, Canada. These huge bears can weigh more than 800kg/1800lbs. This particular male was in no rush. He was waiting at the water’s edge in anticipation for the big freeze: an annual event when the ocean turns into a rock-solid pathway. This ice allows him to hunt his primary prey, the ringed seal. Our warming climate is delaying the arrival of the big freeze by about a day each year. That means that this bear has lost a month of hunting that previous generations relied on. Follow @bertiegregory for more wildlife adventures. #wildlife #animals #snow #canada #frozen
