英语听力：自然百科 探索世界奥秘之Wild Africa - Deserts(浩瀚沙漠) Unit01

Africa is dominated by deserts, from the Kalahari in the south to the mighty¹ Sahara in the north. These are fascinating worlds, each one unique, all a challenge. Yet life can conquer them and in the most surprising ways. This is an epic² journey across Africa's magnificent deserts, a story of survival against the odds³.

Africa. Seen from space, great swathes of sand and rock cover more than half the continent. In the far south, bordering the Atlantic is the world's most ancient desert, the Namib. For eighty million years, cold, dry winds have swept in from the ocean, denying the land moisture and piling enormous sand dunes⁴ against the shore.

Beautiful but impossibly dry, in a good year, the Namib gets just five centimeters of rain; in a bad year, it rains only sand. But buried within the dunes, there is treasure. Fragments of dead animals and plants swallowed long ago by the sand are swept to the surface, offering a crucial lifeline.

Beetles⁵, many different species have found ways to harvest this bounty⁶. Along with termites⁷ and lizards⁸, they're the foundations for a delicate chain of life in the Namib.
