Two countries have made a big new splash in ocean conservation. Niue, a tiny island in the South Pacific, has committed to protecting 49,000 square miles of ocean, including one of the world’s best habitats for reef sharks. Additionally, Chile will create two new reserves totaling 240,000 square miles. Both countries will restrict fishing in the new marine protected areas. All three reserves were scientifically supported by National Geographic Society’s Pristine Seas program.
