The aim of the BBC series Human Planet is to examine “mankind’s incredible relationship with nature in the world today.”
It follows through with that aim in a recent episode “Deserts – Life in the Furnace” that featured a clip of the “…one day of the year [when] the Dogon people of Mali can fish in the sacred water of Lake Antogo. It’s every fisherman for himself as the lake is emptied in minutes.” The event is an annual festival, timed with the changing of the seasons. The clip is short, and you can get more insight on the Dogon people here or here.
