The Great Barrier Reef is the largest living structure on Earth, with rich corals spanning an area larger than New Zealand and visible from space. The Reef is a unique ecosystem; home to thousands of species of marine life, including fish, whales, dolphins, and six of the world’s seven species of marine turtle. The Reef is an irreplaceable global icon. But our Reef is coming under increasing pressure from a growing combination of manmade and natural threats. You can join the effort to help save the Great Barrier Reef.
