Great Barrier Reef

The Great Barrier Reef is the world's largest coral reef system, located off the coast of Queensland, Australia. It spans over 2,300 kilometers (1,400 miles) and is composed of thousands of individual reefs and islands. Home to a diverse range of marine life, including fish, corals, and sea turtles, it plays a crucial role in ocean ecosystems. The reef is not only a UNESCO World Heritage site but also supports tourism and fishing industries. However, it faces threats from climate change, pollution, and overfishing, prompting conservation efforts to protect its delicate environment.
