Natural Phenomena and Coral Ecosystems

The video explores the transformation of a prehistoric landscape into the Great Barrier Reef. It begins with a description of the area 20,000 years ago, covered in forests and inhabited by Aboriginal people. The end of the last Ice Age caused sea levels to rise, flooding the coast and leading to the formation of the Great Barrier Reef. The video details the creation of a lagoon and islands, and highlights the reef's vast size, visible from space.
