Swim out beyond the sandy sea of the Florida coast to the flamboyant coral reefs beneath the waves of the ocean floor. Just out of reach, a towering brain, and staghorn coral comes into sight. What used to be a dazzling array of life now lies a vast, colorless vicinity of almost nothingness. What’s happening in the Florida gulf coast is a scene repeated in reefs across the globe as part of a largescale phenomenon. In recent years, scientists have discovered an unprecedented die-off in coral reefs due to a combination of factors including overfishing, coastal development, coral bleaching and linked to the rising temperature in the ocean as well as human impacts.
