The world's largest coral colony
世界上最大的珊瑚群

Sadly, over the years, climate change has warmed up the world's 11. This has caused many coral reefs to 12 and turn white. But this huge coral colony is very healthy. It may be able to live in 13 waters, scientists say. That is good news, 14 this colony may help produce new coral colonies that can live in warmer waters. The huge coral colony is also important for the Solomon Islands. The country has protected its 15 in the past. It will protect the area even more in the future.
