Resilient to five mass extinctions, corals are among the oldest organisms on Earth. They provide habitat and refuge for many species, hosting about 25% of marine life. Additionally, they help reduce wave energy and coastal erosion. Although they may appear to be plants or rocks, corals are actually soft-bodied animals (known as polyps). However, their survival is now at risk, threatened by climate change and human activities. Over the past few decades, approximately 50% of the world’s coral reefs have been destroyed or severely damaged, and the same is happening in the Mediterranean, home to precious and little-known corals. The loss of these delicate organisms will not cease unless urgent and effective actions are taken to protect them. In order to ensure their conservation, the Marevivo Foundation has launched ‘MedCoral Guardians,’ a project aimed at safeguarding Mediterranean corals, which seeks to raise awareness among citizens through educational and research activities targeting students and divers.
