Edward Stourton explores the Jordan, one of the most powerfully symbolic rivers in the world. Edward reaches the end of his journey. The Jordan flows into the Dead Sea, the lowest point on earth. But by the time it gets there the Jordan is a sad shadow of what it once was. So diminished, in fact, that it raises a paradoxical question - is the Dead Sea dying? This series is available until 11.00am on 23rd September as part of the Series Catch-up Trial.
