explores how scientists from across disciplines are collaborating on projects that offer glimmers of hope for the future of coral reefs.Globally, coral reefs are at a crisis point; warming seas have caused corals to bleach and die at an alarming rate. Five hundred million people worldwide rely on reefs for food and to protect coastlines from storms and rising sea levels. But without action, scientists predict that nearly all reefs could die off in the next few decades.
In CHANGING PLANET"Coral Special," Sanjayan visits Laamu Atoll in the Maldives to take part in a first-time collaboration that could be the key to restoring reefs. Professor Peter Harrison from Southern Cross University in Australia has devised a fertility treatment to help corals reproduce more successfully: “coral IVF.”Corals spawn on just a few nights a year, releasing billions of eggs and sperm into the ocean. The resulting larvae settle on a reef and grow to become baby coral.
in the UK discovered that coral larvae move towards the sound of a healthy reef — and it is fish vocalizations, in particular, which trigger them to sink to the bottom, settle and grow. The scientists’ audacious plan is to combine Peter’s fertility technique with Steve’s fish recordings to lure them to set up home on a damaged reef. This method has never been tried before, but if it works, it could be a global game changer for reef restoration.In the U.S.
