DAR supports critical planning efforts, community action, awareness-raising activities, scientific research with direct management applications, and on-the-ground management projects. That's why so many oceanographers and scientists are working hard to stop the extinction of coral reefs. Even if heavy fishing activity in a reef does not directly damage the coral, overfishing of herbivores such as parrot fish will result in damage because no protection is left against fast-growing seaweed which always threatens to engulf reefs.
