Coral reefs
are diverse underwater ecosystems held together by calcium carbonate
structures secreted by corals. Coral aquaculture, also known as coral farming, is
showing promise as a potentially effective tool for restoring coral reefs, which have
been declining around the world.
Marine protected areas (MPAs) have become increasingly prominent for reef
management. MPAs promote responsible fishery management and habitat protection.
Much like national parks and wildlife refuges, and to varying degrees, MPAs restrict
potentially damaging activities.
