Protecting coral reefs

Endangered coral reefs and the ambitious new conservation efforts to protect and restore coral colonies around the world.

Global warming, pollution and over fishing are destroying many of the world’s coral reefs. In this documentary from "The Changing World," Andrew Luck-Baker visits a coral reef system off the coast of the Pacific Island nation of Palau, and reports on ambitious new conservation efforts to protect and restore coral colonies around the world.

Fish caught in and around coral reefs provide the main source of protein for hundreds of millions of people. Andrew Luck-Baker examines the irreplaceable resources that coral ecosystems provide and reports on new efforts to immunize coral species from the worst effects of climate change.

A special collaboration between BBC World Service and PRI's "The World," "The Changing World" is a series of powerful documentaries, each of which takes a long look at a single global issue, from geo-political hegemony to world health concerns.
