The Great Barrier Reef, located off the coast of Queensland, Australia, is the largest coral reef system in the world. Stretching over 2,300 kilometers, it comprises around 2,900 individual reefs and 900 islands, making it a UNESCO World Heritage Site. The Great Barrier Reef is renowned for its breathtaking beauty and incredible biodiversity, serving as a habitat for thousands of marine species, including fish, corals, and sea turtles. It attracts millions of tourists annually, contributing significantly to the local economy. However, the reef is facing threats from climate change, pollution, and overfishing, prompting conservation efforts to protect this natural wonder.
