![]() During the 2014-2017 coral bleaching event, unusually warm waters (partially associated with a strong El Niño) affected 70% of coral reef ecosystems worldwide. Many of these threats can stress corals, leading to coral bleaching and possible death, while others cause physical damage to these delicate ecosystems. Other threats are caused by people, including pollution, sedimentation, unsustainable fishing practices, and climate change, which is raising ocean temperatures and causing ocean acidification. Some threats are natural, such as diseases, predators, and storms. Unfortunately, coral reef ecosystems are severely threatened. These ecosystems are culturally important to indigenous people around the world. The net economic value of the world’s coral reefs is estimated to be nearly tens of billions offsite link of U.S. Fishing, diving, and snorkeling on and near reefs add hundreds of millions of dollars to local businesses. Over half a billion people depend on reefs for food, income, and protection. They are also are a source of food and new medicines. Benefits of coral reef ecosystemsĬoral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs. Since both partners benefit from association, this type of symbiosis is called mutualism.ĭeep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. The algae also help the coral remove waste. ![]() In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. Shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues.
