Now the deep ocean's best-kept secrets are being revealed - ancient coral ecosystems hidden from view at great depths. The organism has sequestered those nutrients. Just seaward is a discontinuous band of offshore patch reefs that parallel the Keys and comprise the first major habitat encountered in a seaward progression toward the reef tract. As much as 90% of the organic material they manufacture photosynthetically is transferred to the host coral tissue ( Sumich, 1996 ).

At the very end of his book, McCalman tries not to leave us in fatalistic despair about the reef by sharing the anecdotes of some very resilient humans, determined to not give up. Again, fossil fuel formation is a very slow process. Coral reefs house the bulk of known marine biological diversity on the planet, yet they occur in relatively nutrient-poor waters of the tropics. The coral provides the algae with a protected environment and the compounds necessary for photosynthesis.

During 1998, all the monitored corals showed increased mortality and one species disappeared completely from the reefs for at least seven years. A Purplemouth moray eel is held in a bag to measure its nutrient output. Over time when millions of such corals keep adding to the limestone rocks, it forms a shape and size of a massive coral reef. Currently 50 per cent of all new cancer-related drug research focuses on marine organisms. Management of such reefs already adapted to extreme environmental conditions against more immediate stressors, eg pollution and over-harvesting, is thus an obvious priority to give reefs their best chance against our rapidly changing climate.

Much of the carbon dioxide that enters the atmosphere dissolves into the ocean. Mangroves are useful to Belize because they protect the land during times of hurricane and other storms. And it is people who will be affected by these consequences. If so, we may need to rethink the past 2°C climate change guardrail and readjust it to 1.5°C or even lower. Coral reefs provide a lifeline to millions of people in terms of fish protein in their diets, to the local community’s income and social benefits in areas where scuba diving is well managed, together with national marine park entrance fees and responsible coastal tourist development.

Efforts should include enforcing laws against coral destruction, controlling pollutants, and controlling coastal development. Programs are also underway in the Marshall Islands, Western Samoa, and the Federated States of Micronesia. And why should humanity care what happens? People are responsible for both the local degradation of reefs due to over-exploitation and pollution, and the global-scale consequences of interfering with the Earth’s climate system.

Where wave action is severe, living corals are practically nonexistent, but in situations of more moderate wave action, the reef crest tends to be dominated by stoutly branching corals. The majority of research done to date has been performed in the Caribbean, where some generalization can be made about the community structure and distribution of MCEs. Fringing reefs are located close to shore, separated from land by only shallow water.

The base is attached to a hard surface and the open end is the mouth with little tentacles that circle the mouth like a crown. At home, residents can cut down on their use of fertilizers, pesticides and cleaning products that mostly contain chemical ingredients to limit water pollution. Mangroves are lost because of clearing for development, logging, and shrimp farming. Coral reefs are found in warm shallow waters and act as natural barriers along continents. CO2 budgets associated with keeping average sea surface temperature increases to less than 2°C above pre-industrial times require that total emissions due to use of fossil fuels be limited to no more than 1000 GT of CO2 after the year 2000 [15,16].

Algae provides a source of food for smaller fish and invertebrate sea life while also acting as the glue that helps the coral reef grow larger.

All these systems exert a stabilizing effect on the environment, resulting in important physical and biological support for the other communities (Amesbury and Francis 1988). The term describes a condition where higher water temperatures heat the coral, which becomes stressed and expels the microscopic plants that give it its vibrant color. The diversity of reef corals, i.e., the number of species, decreases in higher latitudes up to about 30° north and south, beyond which reef corals are usually not found.
