Without many predators or any prey, rhinos flourished for millions of years. Humans put an end to that, as we hunted them down and destroyed their habitat.No rhino, however, is doing worse than the northern white. Just two, Najin and Fatu, both females, remain.In his narrated story, Sam Anderson, a staff writer at The Times Magazine, visits the pair at the Ol Pejeta conservancy in Kenya, speaks to the men who devote their days to caring for them and explores what we will lose when Najin and Fatu die.This story was written by Sam Anderson and recorded by Audm.
