[00:01:19]As the weather warms, 隨著天氣變暖 [00:02:50]the ice beneath the bears' feet starts to break up and then melt. 北極熊腳下的冰層開始分裂融化 [00:07:39]And as the ice dwindles, 冰層消逝 [00:09:20]so do the bears' chances of a successful hunt. 北極熊狩獵的成功率也隨之驟降 [00:16:18]Most of the ice is lost over these shallow coastal waters, 近海淺水表面的大部分冰層都已融化 [00:20:09]where most of the seals live. 大多數(shù)海豹生活在這里 [00:21:45]It's now summer and these bears have a choice- 現(xiàn)在處于夏季 北極熊們有兩種選擇 [00:31:01]take their chances on the shrinking ice floes, 前往正在消融的浮冰上冒險(xiǎn)覓食 [00:32:59]or make for the safety of the land. 或留在陸地上確保安全 [00:41:21]It's a case of sink or swim. 不想被淹沒 就得游走 [00:43:36]Bears have always gone hungry in the summer, 在夏季 北極熊容易饑餓 [00:53:51]but the length of time when there's enough ice 但北極大部分地區(qū)的冰層 [00:55:41]for them to go hunting 正在迅速消融 [00:57:03]is getting shorter and shorter, across much of the Arctic. 所以它們的狩獵時(shí)間也越來越短 [01:04:04]This is hitting cubs particularly hard, 這對(duì)熊寶寶的打擊尤其大 [01:07:18]because they can't survive for as long 因?yàn)槿绻衲赣H那樣長(zhǎng)時(shí)間不進(jìn)食 [01:09:24]without feeding as their mother. 它們就無法生存 [01:11:48]Cubs that were born underweight are at the greatest risk. 出生時(shí)體重過輕的熊寶寶 危險(xiǎn)最大
