Marine biologists are increasingly concerned about the rapid decline of coral reef ecosystems worldwide. These underwater structures serve as a critical for a diverse range of aquatic species. However, rising ocean temperatures have triggered widespread events, weakening the coral's resilience. In addition to thermal stress, the process of ocean hinders the ability of corals to build their calcium carbonate skeletons. Scientists are now exploring restoration techniques, such as larval seeding and 3D-printed reefs. Protecting these natural is not just an ecological priority but an economic necessity for coastal communities. Global is vital to mitigate the primary causes of marine degradation.
