What is the threatened status of the world's coral reefs?

• 58% of the world's reefs are at moderate to high risk from human disturbance

• Overexploitation of marine resources (including destructive fishing practices) and coastal development are the greatest threats

Percentage of Reefs at High, Medium and Low Risk (Bryant et al, 1998)

• Reefs in Southeast Asia are the most disturbed

• More than 80% of them are at risk and over half (56%) are at high risk

• Overfishing, destructive fishing practices, sedimentation, and pollution associated with coastal development are the biggest threats
