Climate change, primarily caused by global warming, poses a significant threat to the world’s ecosystems. Coral reefs, in particular, face destruction due to rising sea temperatures and ocean acidification. The effects of climate change are exemplified by the bleaching of coral reefs, leading to their eventual demise. However, a recent study explores the potential of using sound to help rebuild degraded coral reefs affected by climate change and human activities. By replaying healthy reef sounds, researchers observed a higher settlement rate of corals on degraded reefs. While this study offers hope for the survival and recovery of coral reefs, further research is needed to determine the feasibility and scalability of this approach.
