The Great Barrier Reef is an underwater structure located off the coast of Queensland, Australia that is made up of calcium carbonate and living coral. It is one of the largest structures made by living organisms and is home to a diverse array of sea life, including reef sharks, starfish, seahorses, dolphins and more. However, the reef faces threats from human activities like logging, crown-of-thorns starfish, and oil spills, which can damage the delicate coral ecosystem.
