Coral bleaching is a phenomenon where corals lose their vibrant colors and turn white due to stress factors such as rising sea temperatures, pollution, and ocean acidification. This process occurs when the symbiotic algae, called zooxanthellae, that live within coral tissues are expelled, leading to a decline in the coral's health and its ability to recover from environmental changes. Coral bleaching poses a significant threat to marine biodiversity as it impacts the entire ecosystem that depends on coral reefs for habitat and food.
