The very peaks that keep Tibet dry are responsible for the monsoon rains falling farther south 就是这些山峰的存在使得西藏变得气候干燥 也造成了季风雨只落在更远的南方
drawing in warm, wet air from the south. 南方的温湿空气随之而来
preventing clouds moving in from the south, and this casts a giant rain shadow 阻挡了从南飘来的浮云 只在大地上投下了巨大雨影
and nowhere is more impressive than on the veldt of South Africa. 天下最美丽动人的草原非南非的维尔德草原莫属
But further south, summers are longer and the grasslands flourish. 但是在更远的南边 夏天的时间更长,草原更加茂盛
until the summer ends and they're forced to head south for the winter. 直到夏天结束 它们才会被迫南迁过冬
Further south, other bigger predators prowl the tundra. 在北极苔原更远的南边有更大的掠食动物出没
and there are fewer predators than further south. 而且这里的掠食动物比南方少多了
instead of flying south to warmer climes. 而一直坚守在这里经受着北方寒冬的考验
The skuas can survive further south than any other predator 与其他猛禽相比 贼鸥的厉害在于它能在地球的最南端生存
