Where is the world’s largest living coral reef system?

The world’s largest living coral reef system is the Great Barrier Reef, located off the coast of Queensland, Australia. Spanning more than 2,300 kilometers (1,430 miles), the Great Barrier Reef is home to an immense variety of marine species, including fish, corals, sea turtles, and sharks. The reef is a UNESCO World Heritage site and is considered one of the most biodiverse ecosystems on Earth. However, it faces significant threats from climate change, coral bleaching, and pollution.
