Coral reefs deliver ecosystem services for tourism, fisheries and shoreline protection. The annual global economic value of coral reefs has been estimated at anywhere from US$30–375 billion (1997 and 2003 estimates) [14] [15] to US$2.7 trillion (a 2020 estimate) [16] to US$9.9 trillion (a 2014 estimate).
