These sheer cliffs, rising to over 3,000 metres,
那些陡峭的山崖 高耸3000多米
hold back the advancing rain clouds
挡住了前进的雨云
and, as a result, the land beyond them is starved of water.
导致山脉之后的土地干旱缺水
This is the greatest expanse of sand in the world.
此地是世界上最广阔的沙漠
A seemingly-endless desert
一望无际的沙漠
that is the vast parched centre of Southern Africa.
正是辽阔干旱的南非内陆
Thousands of miles to the west,
往西数千公里
where this desert meets the Atlantic Ocean,
直到大西洋沿岸
another current prevails.
另一股洋流占了上风
But the Benguela Current, surging up the west side of Africa,
但冲刷着非洲西部的本格拉洋流
has a very different character.
有着完全不同的特性
It's extremely cold, full of nutrients
它非常寒冷 富含养分
and it's thronged with life.
聚集着众多生物
