So does radioactive effluent, whether from Sellafield, a nuclear reprocessing plant on the west coast of England, or the scrapyards of Russia: between 1958 and 1992, the Arctic Ocean was used by the Soviet Union, or its Russian successor, as the resting-place for 18 unwanted nuclear reactors, several still containing their nuclear fuel.

有放射性的排放物也是如此，无论是来自英格兰西岸的塞拉菲尔德核回收厂，还是来自俄罗斯的废品堆放场：在1958到1992年间，北冰洋被苏联或其接替者俄罗斯用作18个闲弃的核反应堆的搁置处，有些仍含有核燃料。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
