Deserts: Life in the Furnace

Deserts cover a third of the earth's land mass, yet harbor only some 300,000 inhabitants, many of which are (semi-)nomadic hunters/herdsmen, making navigation and adapted animals, such as camels, vital. The only 7,000 years old Sahara, the planet's vastest sand-pan, counts many tribes. The stony Gobi enjoys melting snow, wind-transported in all the way from Siberia, but also counts roaming wolves.
