北極熊

Is this starved polar bear which died as ‘skin and bones’ the ‘categorical proof’ that climate change is wiping out the species?

  • Experts found the carcass of a polar bear in Svalbard in the Arctic Ocean
  • Lack of sea ice and seals forced the bear to search further afield for food
  • Scientists claim climate change has reduced sea ice to record lows and is to blame for the death of this animal
  • But some experts add that commercial trade in Canada is also to blame for falling polar bear numbers

據英國《衞報》報道,該北極熊可能是為了覓食,沿着內陸的峽灣一直走了四個月,約五百至七百五十公里的路程。隨着體內的脂肪一天一天地消耗,牠仍然找不到充足的食物,最終死於飢餓。

北極熊數目 未來45年急跌一半
今次有北極熊被發現餓死並非單一事件。國際自然保護聯盟指出,現時有十二個有紀錄的北極熊種群,約2.5萬隻北極熊,其中八個種群的數量正明顯下降。若海冰繼續加速溶化,估計北極熊數目會在未來四十五年急跌三分一至一半。

另有研究指出,居於加拿大的北極熊亦面對重大危機,海冰溶化嚴重影響牠們的健康及繁殖;有專家提出,由於北極熊愈來愈難覓食,未來或需要採用人工餵飼方法。

旅遊不只是玩樂,保育也很重要。
