The Great Barrier Reef was not built by humans; it is a natural formation created by billions of tiny coral polyps over thousands of years. These organisms secrete calcium carbonate, which accumulates to form the reef structure. The reef serves as a vital ecosystem, supporting a diverse range of marine life and providing protection for Coastlines against erosion and storm surges. Additionally, it plays a crucial role in tourism and fishing industries, contributing to the economy of the region.
