Research demonstrates that marine protected areas aid coral reefs

Research has shown that marine protected areas (MPAs)—areas where fishing and other potentially destructive activities are regulated—are benefitting, not just the fish habitats they are known to aid, but nearby coral reefs as well. MPAs may benefit corals by restoring reef-based food webs and protecting damage from anchors and nutrient runoff…
