$BABAB Coral reefs are among the most biodiverse ecosystems on earth, but they are highly vulnerable to coral bleaching triggered by warming ocean waters. Corals rely on a vital symbiotic relationship with microscopic algae called zooxanthellae, which live inside their tissues and provide them with food through photosynthesis, as well as their vibrant colors. When water temperatures rise even slightly above normal, the stressed corals expel these algae, turning completely stark white and leaving themselves highly vulnerable to starvation and disease.
