Coral reefs are becoming unproductive just when we need them the most.
Reefs supply millions with food and other resources. This ecosystem is facing greater rates of disturbance because of our actions. Too much disturbance reduces the productivity, diversity and resilience of the coral reef ecosystem. Preserving this ecosystem will rely largely on preserving the habitats and species of the coral reef ecosystem.
