Watch BBC Journey From The Centre Of The Earth online: Episode 5 Water

This programme is about man’s struggle with water. Because water is so crucial to us, the really successful civilisations are the ones which have learned how best to exploit it. But whether they can control the water or the water controls them is all down to what’s beneath our feet… the rocks. We look at: the flooding of the Black Sea when the level of the Med rose 10,000 years ago; the connection between rocks and man’s attempts to navigate; the Greeks’ use of sink holes to control their water supply – including how sink holes were used against them by enemies in the battle of Mantinea, back in 418BC; we go to Ephesus in Greece to look at how silting up left the city stranded inland and we finish with the opposite problem happening on the Costa del Sol where beaches are being washed away.
