Great Barrier Reef (GBR)

The Great Barrier Reef (GBR) is the world's largest coral reef system, located off the coast of Queensland, Australia. It spans over 2,300 kilometers and comprises thousands of individual reefs and islands. The reef hosts a vast diversity of marine life, including colorful corals, fish, sharks, sea turtles, and mollusks. It plays a crucial role in supporting ecosystems, tourism, and local economies. The GBR is sensitive to environmental threats such as climate change, ocean acidification, pollution, and overfishing, which threaten its health and the rich biodiversity it sustains.
