World's reef fishes tussling with human overpopulation

al Marine Ecology. "It underlines once again that current management approaches are insufficient to protect marine biodiversity on a large scale, and that holistic approaches combining natural and social systems are needed."

"Not everything was doom and gloom," says coauthor Maria Beger at the University of Queensland. The study reported that at least 25% of the world's reefs remain distant from direct human effects. Those reefs are located on small and isolated areas where human habitation is harsh. "These few reefs are in stark contrast with degraded sites, and may still be able to act as sources to replenish others. This is a fortunate situation that can buy us some time while we figure out effective solutions to this coral reef crisis," she adds.

"Coral reefs are the most diverse ecosystem on the planet, hosting thousands of species and generating numerous goods and services to millions of people worldwide," says Enric Sala, a National Geographic fellow and co-author of the study. "The future of coral reefs and the services they provide to a growing human population depend on how soon countries become seriously committed to regulating human threats."
