Endangered paradise - The Great Barrier Reef

Endangered paradise - The Great Barrier Reef it's about 2000 kilometers long and 380 kilometers wide, in front of the eastern coast of Australia is the biggest and best protected coral reef worldwide. Pollution and climate change afflict this complex ecological system. Scientists have identified three reasons for the die back of the corals. The warming of the oceans is responsible for about ten percent of the reduction. About the half is caused by heavy storms the scientists found out. Another 40 percent of the dying can be traced back to the Crown-of-thorns Starfish which eat the corals and reproduce explosively from time to time.
