Ocean Life - Kiribati's coral reefs: Pacific atolls across hemispheres

The Republic of Kiribati encompasses thirty-two atolls and one raised coral island scattered across three point five million square kilometers of the Pacific Ocean. Spanning both the equator and the one-hundred-and-eightieth meridian, its islands reach into four geographic hemispheres. While the inhabited Gilbert Islands contend with local pollution and heavy resource extraction, the remote and largely uninhabited Phoenix Islands remain shielded from human pressures. As a result, the isolated Phoenix atolls are recognized among the most pristine coral reefs on Earth.
