Last week, the Wildlife Conservation Society (WCS) reported that the coral reefs off the coast of Indonesia that is being destroyed by sea water is unusually warm. In the so-called “one of the fastest events and damaging coral bleaching on record” a big patch of reef off the coast of Sumatra has changed died.Climate poses a serious threat to coral reefs.

Indeed, the Intergovernmental Panel on Climate Change (IPCC) devotes many chapters of the marine ecosystem in 2007 a Report to the coral reefs. International Union for Conservation of Nature (IUCN) lists many species of coral in the “red list” of species threatened her.

Coral reefs are some of the most diverse ecosystems on earth. They occupy only one percent of the world’s sea level, but provide a home for 25 percent of all marine life – including fish that millions of people rely for food.
Usually brightly colored coral reefs because corals live in symbiotic relationship with algae. coral bleaching occurs when environmental stresses such as excessive heat causes the coral to expel algae with which they usually live side by side. When this happens, the coral reefs turn a gray dull and lifeless. If the bleaching is severe enough, corals die from lack of energy and the algae provide oxygen.

Not only is the water temperature increases associated with global warming threatening the survival of corals, as well as increasing ocean acidification caused by the excess atmospheric carbon dioxide is absorbed by the oceans of the world. Coral reefs protect the beach from many countries, especially the islands, from the storm. Thus, loss of coral reefs to place a small island nation, which has been threatened by rising sea levels associated with climate change, in further danger.

Apart from their coast-to protect and promote the utility of biodiversity, coral reefs are also breathtakingly beautiful. The loss of beauty that compounds of biological and ecological losses. If the current level of loss continues, we may lose 70% of the world’s coral reefs in the near future.
This May, the Indian Ocean water temperatures are significantly warmer than normal (about 7 degrees Fahrenheit above the average.) Voltage is related to warm water to kill anything that has some of the most coral reef biodiversity in the world. Indeed, the WCS reported that reefs bleached to 80 percent, with more expected colonies die in the coming months

The loss of coral reefs (which happens to either affected or recovered from the 2004 Indian Ocean tsunami disaster) was a blow to destroy the area, and the world. Not only is biodiversity loss a tragedy in itself, but it comes as an extraordinary loss for local residents, many of them are poor and depend on reefs for their food and livelihoods.
And, unfortunately, not a one-time event, this is a sign of the future. As discussed climate change, the level and nature of environmental change will exceed the ability of corals to adapt. Steady warming and acidification of the oceans of the world will pose a threat to coral reefs around the world, and to the communities that depend on them.
Dr Caleb McClennen, WCS-Marine Program Director, described the death of corals as “another unfortunate reminder that international efforts to curb the causes and impacts of climate change should be done if these sensitive ecosystems and vulnerable human society around the world who depend on them is to adapt and survive. ”
When you duck under the water surface, senses you click into overdrive. Go to your right, bright orange clown fish duck behind a sea anemone temporary retreat to a cave coral moray eels. As you float in the other direction, you see a giant sea fans adorn the underwater scenery and coral branching call in your direction, as if to invite you to join them.

Your scuba diving along one of the many coral reefs scattered throughout the equatorial ocean, catch a glimpse of many of the largest life supports life structure. Your underwater view, however, may be limited. Seventy percent of coral reefs may disappear in less than 40 years if current levels continue the damage [source: Nature Conservancy].
