Every year, more than a million wildebeest, along with hundreds of thousands of zebras and gazelles, move through the Serengeti-Mara ecosystem of Tanzania and Kenya, following the rains. In the course of a year, an individual wildebeest may cover as much as 2,100 kilometers. (That’s more than 1,300 miles — which is further than the distance between New York and New Orleans.) It is the last great migration on Earth.
But for how much longer? A large part of the migration takes place within the vast Serengeti National Park in Tanzania, and there are reports that the Tanzanian government is preparing to build a major road through the northern part of the park: through a designated wilderness area, through the migration route.
