In an unpleasant silence on the surface of the earth, the respiring astronaut observes the mysterious and incompressible miracles of the greatest structure of that creature. Curiosity to see 1500 kinds of fish and 400 kinds of corals is too far, but the glow of this place is unquestionable. As the only creature you can see without the aid of the moon, the glory of the Great Barrier Reef is not limited to the image of the ground, it captures the interest of stars and men. Because it extends south from Papua New Guinea to the east coast of Queensland, Australia, it is different in size from other places and lives more animals and plant species than anywhere in cubic meters.
New Caledonia's coral reef system is considered the second largest coral reef system in the world after Australia's Great Barrier Reef and is the world's longest 600 km long and the world's largest lagoon. Area of 24.000 square kilometers. This ecosystem is concentrated in Fiji with the most diverse coral reef structure in the world. Of which 146 is based on a global classification system comparable to or beyond the much larger Great Barrier Reef in terms of coral and fish diversity.
Coral reefs around the world have been affected by a large-scale bleaching phenomenon for the third consecutive year. The symbolic coral reefs of the Great Barrier Reef in Australia and the Hawaiian Islands in the northwestern part of the United States have experienced the most serious whitening phenomenon in history and have devastating effects. For example, the whitening of the Great Barrier Reef in 2016 and 2017 caused about 50% of coral death. Corals can not tolerate the frequency of current whitening phenomena caused by rising temperature in the world. If the temperature continues to rise, the intensity and frequency of bleaching phenomena will increase. Scientists estimate that even events that occur twice in the decade may threaten the survival of corals.
Coral reefs are widely distributed in warm shallows. They may work as obstacles along the continent (such as the Great Barrier Reef in Australia), the surrounding islands, and atolls. Of course coral reef is the main organism is coral. Coral is interesting because it has both algae (animal) and animal polyps. Due to malnutrition of coral reef water, corals acquire nutrients through algae through photosynthesis and obtain plankton from the water by extending the tentacles. In addition to corals, animals have several microorganisms, invertebrates, fish, sea urchin, octopus, starfish and others.
A wide range of Australia's Great Barrier Reef is declared hundreds of miles dead. Overheated sea water destroyed this magnificent and important natural wonders. Coral reefs are an important source of biodiversity, providing coastal protection, having medicinal value and providing nursery beds ideal for fish and other marine organisms. It is also an important source of protein food for many people. Terry P. Hughes, director of the coral reef research center funded by the government at James Cook University in Australia said, "I did not think that the Great Barrier Reef will suffer such damage within 30 years."
