This film reveals the significance of the Great Barrier Reef to the world and how its own future is intimately linked with global weather patterns and climate.
The Great Barrier Reef is intimately connected to the rest of the world’s tropical seas, with creatures ranging from giant whales to small sea birds passing through its coral cays and lagoons every year. Sharks and turtles migrate thousands of miles across the Pacific to the isolated coral islands of the reef and humpback and minke whales cross the ocean each year from the Antarctic.
The reef also attracts seabirds breeding on its coral cays, and deep sea creatures making their way up from the ocean depths under the cover of night.
