REPUBLIKA.CO.ID, JAKARTA - The existence of coral reefs in Indonesia is prone to extinction. Only 5.58 percent of coral reefs are still in great condition.

Research Center Oceanography of Center for Regional Studies at Indonesian Institue of Science (LIPI) shows that 26.95 percent is in good condition, 36.9 is good enough, and the remaining 30.76 is in poor condition.

"It is worrying. It needs the right solution," the Head of Reseach Center Oceanography of LIPI, Zainal Arifin, said on Thursday.

Fisherman fishing with wrong technic contributes highly to the damage. "Fishing using bomb, poison, gillnet, and trawl damages the coral reefs," he said. 

Poor quality of water also affects the coral reefs badly. The condition of water is influenced by pollution and climate changing. Climate changing impacts the acidity of sea water. Coral reefs cannot grow in poor quality water and acid water.

Water temperature and salinity also scale down the growth of coral reefs. In addition, green house effect kills the species living near coral reefs.
