On one day of the year the Dogon people of Mali in Africa can fish in the sacred water of Lake Antogo. It’s every fisherman for himself as the muddy lake is drained in minutes. This amazing footage was shot by BBC Natural History Unit in Bristol, England and BBC Wales, which spent two years shooting over 70 stories in some of the most remote locations on earth spanning about 40 countries. Each episode of the Human Planet series focuses on a different human-inhabited environment, including deserts, jungles, the Arctic, grasslands, rivers, mountains, oceans, and the urban landscape.  While the series has yet to air in the U.S.,  this web-only Human Planet trailer viewed here is simply astonishing.
