Over the last decade, 15% of the world's reefs have been lost while a further 30% of reefs are severely threatened. Sadly, we are the main contributors to their decline. The damage to reefs caused by occasional natural phenomena is far outweighed by growing human impacts. Key threats facing reefs are:
Once coral reefs are degraded, they lose their value because they are less productive, providing fewer goods and services than healthy reefs. Even if they are only partially destroyed, coral reefs are slow to return to maximum productivity levels. Some scientists estimate that it can take up to 50 years before a destroyed reef is half as productive as it was in its original state.
Imagine a world without reefs. No fisheries, no tourism, and no jobs in vulnerable local economies. We need to raise awareness of their value. Everyone has a role to play.
