The coral reefs are a natural habitat for about a quarter of marine life (Sheppard 65). The reef colonies provide homes and shelter to thousands of marine species. Around 4,000 different species of fish and many other species, including ones that have yet to be discovered, are dependent on coral reefs …show more content…

Marine scientists have begun to observe the degradation of the reefs, more in heavily populated areas. About one fourth of the coral reefs have already died and more are being harmed every day. In the Caribbean, the elkhorn coral covered most of the reefs in the 1970s. It brought in great business for photographers. In just the time span of 10 years, most of the coral was killed from the White Band disease. In 10 more years, there was barely any coral left. The coral could no longer protect the shorelines like it had before and didn’t have much marine life. In Gulf of Aqaba, global warming had strongly affected the coral rich area. The coral had reduced greatly in just 20 years (Sheppard
