Yet around 20 percent of the world’s coral is already gone, and most of the rest is severely threatened by climate breakdown, overfishing and pollution. This is known as bleaching -- because those algae are what give corals their bright colors. A highly biodiverse ecosystem, one with many different species, is often more resilient to changing conditions and can better withstand significant disturbances.
