Alone in a vast expanse of sand, a man treks across giant dunes in Namibia's Namib Desert. One of the driest places on Earth, the Namib necessitates resourceful adaptations. Snakes, spiders, beetles, and lizards can survive here only because fog delivers a wisp of vital moisture as it rolls in from the ocean most nights.
