Vultures: The acid-puking, plague-busting heroes of the ecosystem | Kenny Coogan - a podcast by TED

In the African grasslands, a gazelle suffering from tuberculosis takes its last breath. The animal's corpse threatens to infect the water, but for the vulture, this isn't a problem: it's a feast. With a stomach of steel that can digest diseased meat and waste, vultures are essential to removing dangerous pathogens from ecosystems. Kenny Coogan explores the importance of the desert's cleanup crew. [Directed by Katarina Jukić, narrated by Addison Anderson].
