mhm. Coral reefs are some of the most biologically diverse places on earth, covering less than 1% of the ocean floor. A quarter of all marine life, including two million species, rely on them for survival, and so do we. Coral reefs feed and sustain almost half a billion people, protecting them from storms and tsunamis, encouraging tourism and providing scientific inspiration in the treatment of heart disease and cancer. Some of today's coral reefs began growing 10,000 years ago, yet we have lost over half of our reefs in only 30 years. Ocean acidification and marine heatwaves are the biggest threats. As water temperatures rise, the algae that give quarrels their colours are evicted, known as bleaching, as the corals bleach they staff and can eventually die, along with countless species that rely on them.
