Coral Reefs: Conservation and Impact

The Great Barrier Reef, the world's largest living structure, is under threat from climate change, leading to mass coral bleaching and significant ecological damage. Despite being well-managed, the reef faces risks from global warming, local pollution, and overfishing. Coral reefs are crucial for biodiversity, economic value, and medical research. Urgent international action is needed to reverse climate change and protect these vital ecosystems.
