Suppose The Great Barrier Reef, located off the coast of Queensland, Australia, is the world's largest coral reef system. It is home to a diverse range of marine life, including hundreds of species of fish, turtles, and coral. The reef is a popular destination for tourists and a UNESCO World Heritage Site. However, it faces threats from climate change, pollution, and overfishing.
Can we infer that "The Great Barrier Reef is a man-made structure"?
