The Great Barrier Reef: Earth's Living Wonder | Geography Documentary

Off the north-eastern coast of Australia lies the largest living structure on Earth — visible from space, yet built by animals smaller than your fingernail. Journey along the Great Barrier Reef: more than 2,300 kilometres of coral, islands and ocean life, from the tiny coral polyps that built it to the turtles, sharks and whales that call it home. Discover how it formed, why it is bleaching, and what is being done to save it.
