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

The world’s largest coral reef system is the Great Barrier Reef, located off the coast of Queensland, Australia. It spans over 2,300 kilometers (1,430 miles) and is made up of more than 2,900 individual reefs and 900 islands. The reef is home to a vast array of marine life, including coral species, fish, turtles, and sharks. It is a UNESCO World Heritage site, though it faces significant environmental challenges due to climate change, pollution, and overfishing.
