Scientists Declare The Great Barrier Reef Dead At 25 Million Years. The Great Barrier Reef is considered Australiaâs national treasure as it once was filled with marine life, amazing coral reefs, and crystal clear waters. The incredible Coral Sea Wilderness has been declared dead by scientists at 25 million years old â ending its years of struggle and illness. However, locals claim that the reports of its demise have been exaggerated and there is plenty of life left in the worldâs largest barrier reef.
According to the GBRMPA in 2014, the most significant threat to the status of the Great Barrier Reef is climate change, due to the consequential rise of sea temperatures, gradual ocean acidification and an increase in the number of intense weather events.n 31 January 2014, the GBRMPA issued a dumping permit that will allow three million cubic metres of sea bed from Abbot Point, north of Bowen, to be transported and unloaded in the waters of the Great Barrier Reef Marine Park.
