Hints: Namib life-giving scrub karoo
Where else but the Namib would an ingenious little beetle stagger up the highest dunes on cold mornings, put its back to breeze, and then stand on its head to collect a life-giving drink?Impressive sand dunes dominate the Namib, but to the south and east is a very different kind of desert , an expanse of rocky scrub known as the karoo.
This desert is as old as the Namib, but here it is mainly rain, not fog that drives life. In the karoo, up to 30 centimeters of rain may fall during winter and this extra sprinkle of moisture makes the world of difference.
