From the makers of Earth's Greatest Rivers, Earth's Tropical Islands journeys to three of the most exotic, mysterious and remote islands on planet Earth: Madagascar, Borneo and Hawaii. In three episodes, the series reveals how these isolated and iconic tropical islands harbour remarkable wildlife and human castaways found nowhere else on Earth. Madagascar is the oldest island in the world, Borneo cradles more diversity of life than any other island, and Hawaii is the remotest island chain in the world. In a rapidly changing world, these fragile islands are a vital gauge for the health of our planet.
