Why Coral Is Dying Around The World

For this week’s Please Explain we explore the critical role coral reefs play in marine life and how they’re threatened by “coral bleaching," which is a sign of mass coral death. We’ll be joined by Jeff Orlowski, director of the new Netflix documentary “Chasing Coral," along with Ruth Gates, a scientist who appears in the film and is the director of the Hawaii Institute of Marine Biology, University of Hawaii at Manoa.

"Chasing Coral" is out now on Netflix.
