Ethiopia's Afar low plain is a lunar landscape of craters and saline lakes in hellish heat. By extreme contrast, over thirty million years, half a million cubic kilometer lava created an equally bizarre mountain range nearby.
The giant East African Great Rift, a vast plane, includes several lakes. Those are surprisingly diverse biotopes, some with extraordinarily unique food chains. One is even filled with poisonous volcanic minerals, which only the pink flamingo (colored by it) thrives in as predator.
The final program is about the savannah ecosystem and the animals that live on it. The final scenes of the program suggest that the Rift Valley is the cradle of humanity.
