The Last Reef: Cities Beneath the Sea

Fly across iridescent tropical reefs, brush through a cloud of a million jellyfish, and visit an alien world where the closer you look, the more you see. We think of reefs as exotic, distant places with little or no connection to our everyday world. Yet every reef is a living city beneath the sea with a parallel existence to ours, distant yet undeniably connected.

Reefs are hotspots of biodiversity as vital to life on Earth as the rainforests. They have been shaping our shorelines, literally forming islands and mountains, for millions of years. But the world's coral reefs are also vanishing at five times the rate of the rainforests and could be gone within our lifetime. Like cities on land, though, reefs can rebuild. Catch a glimpse of the future with an inspirational vision of the reef's incredible power to flourish again.
