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).

Then, once the urchins reach young adult size, the researchers place them in a coral reef in need of extra support. Correspondent Maura Barrett helps researchers place adult-sized urchins in a reef.
The mass bleaching of coral reefs around the world since February 2023 is now the most extensive on record, the National Oceanic and Atmospheric Administration (NOAA) told Reuters this week. A ...
Whilst coral reefs are bleaching in tropical areas like the Great Barrier Reef, even more striking, and perhaps more alarming; is the growth of tropical coral species in temperate regions, which has taken place over the past decade. Coral reefs are frequently compared to the "canaries in the coal mine," who were used by miners as an indicator ...
The coral reefs are also the perfect habitat for rare and economically important species of tropical fish, as they provide the perfect area for fish to breed and create nurseries in. [46] If the populations of the fish and corals in the reef are high, then we can use the area as a place to gather food and things with medicinal properties ...
Coral reefs also help coastal communities by forming a protective barrier against storm surges and large waves. This helps to avoid property damage for more than 5 million people worldwide, a 2022 ...
Catch-up reefs initially grow more slowly than sea level rises but eventually catch up when the rise in sea level slows or stops. Give-up reefs are not able to grow fast enough and are "drowned out". There are six different major ways in which fringing reefs grow and develop. [4] Reefs can develop vertically as far as the space below the ...
Florida’s Coral Reef, the more than 6,000 species that call it home, and the vibrant recreational economies and coastal communities that rely on it need these protections now more than ever.
