Planet Earth

David Attenborough takes a look at deserts, which cover a third of the Earth's land surface. From space they appear lifeless but a closer look reveals a different picture.Deserts, in fact, are surprisingly varied; from Mongolia's Gobi desert where wild Bactrian camels have to eat snow in lieu of water, to the Atacama in Chile where guanacos survive by licking the dew off cactus spines.
