Where is the world’s largest coral reef?

The world’s largest coral reef is the Great Barrier Reef, located off the coast of Queensland, Australia. Stretching over 2,300 kilometres (1,430 miles), it is made up of more than 2,900 individual reefs and 900 islands. The Great Barrier Reef is one of the most biodiverse ecosystems on Earth, supporting thousands of species of marine life, including fish, corals, and sea turtles. It is also a UNESCO World Heritage Site, though it faces threats from climate change, coral bleaching, and pollution.
