Colourless, tasteless, odourless, and ageless: water is both the simplest thing on earth and the most complex. We cannot live without it yet it kills six thousand children a day. It is the ultimate renewable resource but we pollute it without thinking twice. Why, if water is so valuable does nobody want to pay for it unless it comes in a designer bottle? Is it really the oil of the twenty-first century? Will we all soon be fighting over it, or can it lead countries into co-operation rather than conflict? In this enthralling voyage of discovery, Rupert Wright sets out to discover exactly what water is and why it plays such an important role in history, culture, art and literature. Part reportage and part personal journey, Take Me To the Source is the fascinating story of the substance that makes life on earth possible.
