The world’s coral reef systems are as stunning as they are complex. Coral is the foundation of marine ecosystems that provides housing and food for millions of species. It is of great importance that we take care of these living creatures, as the ecosystem we rely on as humans is largely dependent on the health of the seas and their inhabitants. Divers should be acutely aware of this and practice the age-old admonition, “Look, but don’t touch!”
