Australia's Great Barrier Reef not 'in danger': UNESCO
UNESCO has voted to leave Australia's Great Barrier Reef off its "List of World Heritage in Danger" despite several reports claiming major coral bleaching at the 2,300-km-long ecosystem. However, the UN body expressed "serious concern" about the reef's health. The reef, which is also the largest living thing on Earth, was recently valued for the first time, at $42 billion.
