Chasing Coral (2017)

Coral reefs are the nursery for all life in the oceans, a remarkable ecosystem that sustains us. Yet with carbon emissions warming the seas, a phenomenon called “coral bleaching”—a sign of mass coral death—has been accelerating around the world, and the public has no idea of the scale or implication of the catastrophe silently raging underwater.

Unfortunately the movie Chasing Coral is not yet available on HBO Max.
