　　　　Spending summers on land and winters traveling from iceberg▼ to iceberg is not an easy life. Their fur helps them blend into their surroundings, but polar bears living in the Arctic are threatened by climate change more than being spotted by their prey. Melting icebergs mean that many animals are suffering from a loss of their habitats. Destination Wild's Polar Bear Invasion episode is the latest special from National Geographic Channel (NGC) that follows these bears on their journey to raise cubs▼ in the harsh climate of the North.
　　　　Unlike other species of bears, polar bears don't sleep through the winter months, and they spend their winters living in the cold and snow of the subarctic▼ and Arctic areas. The crew of Polar Bear Invasion manages to follow several bears relying on their instincts to travel around the icy, snow-covered landscape. Seeing up-close▼ how polar bears live, and the challenges they overcome every day, really illustrates how hard life is for these animals.
　　　　From late fall, polar bears migrate north to the ice floes▼ of the Arctic to hunt for fish and seals. They can only swim for so long before they run out of energy, so the melting icebergs are a serious problem for polar bears. If there is less ice, then the bears have nowhere to hunt from, so they get stranded▼ in the water and drown. Many also starve while stuck on an iceberg where there is nothing to eat nearby. Most scientists agree that the major cause of climate change is the burning of fossil fuels▼, so help save the polar bears by conserving resources. Learn some fascinating facts and observe the lives of these arctic hunters on NGC's Polar Bear Invasion.

北極熊的入侵
來看看北極熊在地球上最寒冷的地方之一奮力生存的生活吧。

　　夏天在陸地上活動，而冬天在冰山間遊走的生活十分不易。北極熊的毛幫助牠們融入環境，但生活在北極的牠們受到氣候變遷的威脅遠遠大於被獵物發現的威脅。融化的冰山意味著許多動物正遭受棲息地消失的危害。《野生大地之旅》的《北極熊的入侵》是國家地理頻道的最新特輯，這集緊跟著這些熊踏上在北方嚴峻氣候下撫養小熊的旅程。
　　跟其他種類的熊不同的是，北極熊不會冬眠，而且會住在近北極或北極的區域中度過冬季。《北極熊的入侵》的工作人員設法跟著這些熊，牠們依靠本能行走在結冰且被雪覆蓋的陸地上。近距離觀察北極熊如何生存及牠們每天所克服的挑戰，真的描繪出對這些動物來說，生活有多麼不易。
　　從深秋開始，北極熊會北遷到北極地區的浮冰上去獵捕魚及海豹。牠們僅能在耗盡體力前的這段時間游泳，因此持續融化的冰山對北極熊而言是個嚴重的問題。如果冰減少了，那麼這些熊就沒有地方可以捕食，而且會受困在水中溺斃。許多北極熊也因被困在附近沒有東西可吃的冰山上而餓死。大多數的科學家認為導致氣候變遷的主因是燃燒化石燃料，所以藉由節省資源來幫忙拯救北極熊吧。鎖定國家地理頻道《北極熊的入侵》，你會得知一些驚人的事實並觀察這些北極獵食動物的生活。
