有證據顯示澳大利亞的大堡礁正遭受有記錄以來最嚴重的珊瑚白化現象，科學家們再次呼吁聯合國將其列入世界瀕危遺產名錄。請聽  BBC Jon Donnison 的報道。

The Great Barrier Reef is considered one of the seven wonders of the natural world. But the study from Australia's National Coral Bleaching Taskforce found that in some areas, 95% of the reefs are now severely damaged.

On the northern section running between Cairns in Queensland and Papua New Guinea, only four out of 520 reefs are untouched. Coral bleaching is caused by rising sea temperatures. It can take decades for the coral to recover. And persistent warmer waters kill the reefs altogether.

Last year UNESCO, the UN's scientific body, decided not to list the World Heritage Site as 'in-danger'. Environmentalists are now calling for that decision to be reassessed.
