Where is the world’s largest coral reef system?

The world’s largest coral reef system is the Great Barrier Reef, located off the coast of Queensland, Australia. Spanning over 2,300 kilometers (1,430 miles), it is home to thousands of species of marine life, including fish, corals, mollusks, and sea turtles. The Great Barrier Reef is a UNESCO World Heritage site and plays a critical role in marine biodiversity and ocean ecosystems. However, it is under threat from climate change, coral bleaching, pollution, and overfishing.
