The evaporating Mediterranean Sea | BBC

Six million years ago the continents of Africa and Europe collided to close the Strait of Gibralter. Starved of water, the Mediterranean Sea evaporated to form a vast desert. The legacy of this vanished ocean? A million years' worth of salt deposited in mines half a kilimetre beneath the island of Sicily. Extraordinary footage taken from the ground-breaking BBC series Earth: The Power of the Planet.
