Kingman Reef
http://t1.g.hjfile.cn/listen/201304/201304170738104421839.mp3The story of land building in the South Pacific may start with volcanic eruptions, but it doesn't end there. A volcano once formed an island here, but it sank back below the surface. Now it's on the rise again. This is the extraordinary Kingman Reef. Over 3,000 miles from the nearest continent, it is one of the last pristine coral reefs left in the world. As tourism and fishing are banned here, the reef is about as close as you'll get to the Pacific as it used to be before humans arrived. Part of what makes Kingman extraordinary is the 200 types of coral found here. But there's also something else. And it's helping to build the reef. Giant clams, everywhere. More than you'll see on any other reef in the world.
