Presentation: Namibia

Namibia is a country located to the northwest of South Africa, west of the Kalahari Desert in Botswana, and south of Angola.  At 2.5 million inhabitants, it is one of the least densely populated countries in the world.  It has the lowest rainfall of any Sub-Saharan African country, and the Namib Desert that borders the Atlantic Ocean is the oldest in the world.  The cold Benguela Current travels up the coast, producing fog that extends inland until it reaches the Great Escarpment, a geologic feature that extends south and around the country of South Africa to the east.  Namibia is home to some of the most iconic succulents in the world, some of the oldest exposed rock formations, and many familiar animals adapted to survive in the desert environment.
