bleaching events

Bleaching events refer to the phenomenon where coral reefs lose their vibrant colors and turn white. This occurs primarily when corals become stressed due to factors like rising sea temperatures, pollution, or ocean acidification. When stressed, corals expel the tiny algae (zooxanthellae) that live inside them, which provide essential nutrients and color. Without these algae, corals not only lose their color but also their main food source, making them more susceptible to disease and death. Bleaching can lead to significant ecological and economic consequences, as coral reefs support diverse marine life and coastal communities.
