Climate change, pollution, crown-of-thorns starfish and fishing are the primary threats to the health of this reef system. Other threats include shipping accidents, oil spills, and tropical cyclones. Skeletal Eroding Band, a disease of bony corals caused by the protozoan Halofolliculina corallasia, affects 31 coral species. According to a 2012 study by the National Academy of Science, since 1985, the Great Barrier Reef has lost more than half of its corals with two-thirds of the lost occurring from 1998 due to the factors listed before.

Famous quotes containing the word threats:
“Among the best traitors Ireland has ever had, Mother Church ranks at the very top, a massive obstacle in the path to equality and freedom. She has been a force for conservatism, not on the basis of preserving Catholic doctrine or preventing the corruption of her children, but simply to ward off threats to her own security and influence.”
—Bernadette Devlin (b. 1947)
