The region known for having the world's largest coral reef is the Great Barrier Reef, located off the coast of Australia. This UNESCO World Heritage site stretches over 2,300 kilometers and is renowned for its breathtaking marine biodiversity, hosting thousands of species of fish, corals, and other marine organisms. The Great Barrier Reef is not only significant ecologically but also economically, supporting tourism, fishing, and research industries. However, conservation efforts are being intensified due to threats from climate change, pollution, and invasive species, aiming to protect this natural wonder for future generations.
