The Arabian camel--not even a native , was domesticated 1 in the deserts of Asia and brought to Northern Africa as a means of transport. In the past , Tuareg nomads 2 used camels to move slaves, gold and ivory between West Africa and the Mediterranean 3. Today their caravans 4 still trade in salts, dates and millet 5.

The Sahara has long been a frontier between Asia and Africa. But there are European pioneers here too--red foxes, which scrape a living
on the Northern fringes of this vast desert.

Though much of the Sahara is uninhabitable, there are a few special places where life can thrive. The Ennedi Mountains in Chad harness a little more moisture from clouds than lower-lying areas enough to support tiny pockets of Savanna 6. Here rock hyraxes survive on the leaves of acacia trees, a scene more typical of the African plains. These green islands are relics 7 of an older world, one which is slowly vanishing with the march of the desert sands.

The Sahara , as we know it today, is only 2, 000 years old, the product of a rapidly drying climate in North Africa. But our ancestors also had a hand in this change. By over-cultivating marginal lands, and intensively grazing livestock 8. Before, things were very different. Try to imagine this land flooded by the ocean, swathed in forest and savannah, swept by mighty 9 rivers.

Ennedi Gorge 10 once fed a vast tributary 11 of the Nile. Today all that remains 12 are a few precious pools, crucial watering holes for passing caravans of camels. In just 10 minutes of drinking , these remarkable 13 animals can put on a third of their body weight in water. It's enough to carry them for well over 100 kilometers to the next oasis 14.
