Global warming, pollution and over fishing are destroying many of the world’s coral reefs. In this documentary produced for the BBC World Service, 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.
FIRST HALF
On one evening each year in a spectacular mass mating event, millions of corals simultaneously release billions of eggs and sperm into the waters around Palau. The BBC’s Andrew Luck-Baker witnesses the mass spawning episode and follows the scientists who are trying to use some of Palau’s coral spawn to repopulate endangered coral reefs elsewhere.
Second Half
Fish caught in and around coral reefs provide the main source of protein for hundreds of millions of people. In this documentary, 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.
