The Great Barrier Reef off the eastern coast of Australia is the largest reef system in the world. In 1981, the reef was designated a World Heritage Site but it has faced persistent threats from natural and human causes. Now the health of the reef is in serious trouble. As is the case with coral reefs around the world, it is in extreme distress due to effects of climate change. The warming of the climate has led to increased temperatures of ocean water which has led to mass coral bleaching. A recent study by UNESCO of reefs around the world states the situation is now dire.
