The Great Barrier Reef, located off the coast of Queensland, Australia, is the world's largest coral reef system. It stretches over 1,400 miles and comprises nearly 3,000 individual reefs and 900 islands. This vibrant ecosystem is home to thousands of marine species, including fish, corals, and turtles. The reef is a UNESCO World Heritage Site and is often referred to as one of the Seven Natural Wonders of the World.

The Great Barrier Reef faces threats from climate change, pollution, and overfishing. Coral bleaching, caused by rising sea temperatures, poses a significant risk to its health. Despite these challenges, conservation efforts aim to protect this vital marine habitat. Visitors can explore the reef through snorkeling, diving, and eco-tours, offering a glimpse into its breathtaking underwater world.
