As winter deepens,
隨著冬季的深入
frigid air from the Arctic
從北極來的冷空氣
meets warm, moist air from the south,
與南方溫暖濕潤的空氣相遇
producing particularly heavy snows.
形成了漫天的暴雪
For the big animals of the forest,
對于森林中的大型動物
there's no way of hiding from the winter.
寒冬似乎無法躲避
But size, for the bison of Northern Canada,
但對加拿大北部的野牛來說
is, in fact, their salvation.
體積大 反而成了它們的優勢
Big bodies lose less heat

and can carry more insulation.
而且隔熱效果好
That may be why these bison
這也解釋了為何這些野牛
are the largest land animals in North America.

And only a large predator can tackle them.
只有大型的食肉動物才能擒獲它們
Wolves hunt better in packs,
狼 以集體狩獵見長
but there are only two of them here
但目前只有兩匹狼作伴
and the prey they pursue are giants.
而它們追捕的獵物卻體型碩大
