Coral skeletons also are being used as bone substitutes in reconstructive bone surgery. They provide important medicine, and a compound that blocks ultra-violet rays. Coral reefs even help reduce global warming by taking carbon dioxide out of the air. Coral reefs provide a house for many species. If they were to become extinct then future generations would not have the benefits that these animals have to offer, such as possible medicines, pest control, and carbon dioxide control. Fisheries are also contributed by corals, and if they were eliminated it would reduce the food source greatly. With the technology that has rapidly been discovered, we learn more and more about what we can do with bone structure and hard corals. Right now scientists are doing restructuring procedures and learning that bone tissue and blood vessels spread into the coral graft which eventually the bone replaces most of the coral implant.
