Can Coral Reefs Survive the 21st Century?
The Great Barrier Reef and the other great coral reefs are the largest living structures on the planet and among the world's most diverse ecosystems. Now some are suggesting up to a fifth of the world's reefs have already been destroyed. So how can we ensure the continued survival of the remaining coral reefs? And how can we meet the world's growing food and energy demands while still protecting fragile coral reefs? Hosted by Robyn Williams, leading experts and practioners meet in Cairns to debate these issues in front of an informed audience.
