The story is ongoing: As natural resources dwindle, global powers are racing to mine new frontiers of the jungles, the oceans, the Arctic north.
故事还在继续：随着自然资源的减少，全球大国正在竞相开采丛林、海洋和北极北部的新领域。
Antarctica, the world’s last true wilderness, is protected by a treaty, signed by 42 countries, that imposed a ban on resource extraction from the continent, except for scientific research purposes.
南极洲是世界上最后一片真正的荒野，受到42个国家签署的一项条约的保护，该条约禁止从南极洲开采资源，除非是为了科学研究目的。
But nations are jockeying for access to Antarctic fishing, mining and oil reserves.
但各国都在争夺南极的渔业、矿业和石油储备。
Even if the treaty remains in place, all is not well at the bottom of the planet.
即使条约继续生效，地球底部也并非一切都好。
When Shackleton and his men voyaged to Antarctica, they entered a frozen world.

Pictures of Endurance, taken by the expedition’s photographer, Frank Hurley, show the great ship iced into place, high and dry on the ocean’s wintry wastes.
探险队的摄影师弗兰克·赫尔利拍摄的“坚忍号”号的照片显示，这艘巨轮被冰封在原地，在海洋的冬季荒地上高耸着、保持船身干燥。
The images are iconic; they are also documents of a landscape that is vanishing quickly.

Once, the ice that covered the Weddell Sea made underwater exploration impractical, but in recent months the thickness of that ice has been at some of the lowest levels ever recorded.
曾经，威德尔海的冰层使得水下勘探变得不切实际，但最近几个月，冰层的厚度达到了有记录以来的最低水平。

Scientists worry that ancient pathogens may be unleashed along with them — that our next pandemic might be a disease that felled our ancient ancestors.
科学家们担心，远古的病原体可能会随之释放——我们的下一次疫情可能是一种曾使我们远古祖先灭绝的疾病。
Graver still is the vast quantity of carbon, trapped in undecayed plant matter for thousands of years, that is released into the atmosphere as permafrost thaws, creating a feedback loop: temperatures rise, soil melts, gases disperse, temperatures rise further.
更严重的是，大量的碳被困在未腐烂的植物物质中数千年，随着永冻层融化，它们被释放到大气中，形成一个反馈回路: 温度上升，冻层土壤融化，气体扩散，温度进一步上升。
In Shackleton’s time, the hardiest adventurers — those strivers to the uttermost — made journeys to the poles.
在沙克尔顿的时代，坚韧不拔的冒险家——他们不断奋斗、毫不松懈——踏上了南极之旅。
Now, as glaciers dissolve and sea levels rise, the poles may, in effect, journey to us, swamping our shores.
