Great Barrier Reef 'severely damaged' 大堡礁“严重受损”

文字稿

有证据显示澳大利亚的大堡礁正遭受有记录以来最严重的珊瑚白化现象,科学家们再次呼吁联合国将其列入世界濒危遗产名录。请听  BBC Jon Donnison 的报道。

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.
