Coral reefs represent some of the most biodiverse marine ecosystems on Earth, harboring nearly a quarter of all ocean species despite covering less than one percent of the seabed. However, rising sea temperatures have triggered widespread coral bleaching, where corals expel the symbiotic algae in their tissues. Without these microscopic organisms, corals lose both their vibrant coloration and their primary source of energy, making them highly to disease and mortality. Marine scientists advocate for localized conservation efforts alongside global climate action to reef resilience against future ocean warming shocks, ensuring these vital coastal barriers do not permanently.
