The water coming out of your tap is four billion years old and might have been slurped by a Tyrannosaurus Rex. We will always have exactly as much water on Earth as we have ever had. Water cannot be destroyed, and it can always be made clean enough for drinking again. In fact, water can be made so clean that it actually becomes toxic. As Charles Fishman brings vibrantly to life in this delightful narrative excursion, water runs our world in a host of awe-inspiring ways, which is both the promise and the peril of our unexplored connections to it.

Taking listeners from the wet moons of Saturn to the water-obsessed hotels of Las Vegas, and from a rice farm in the Australian outback to a glimpse into giant vats of soup at Campbell's largest factory, he reveals that our relationship to water is conflicted and irrational, neglected and mismanaged.

Portraying and explaining both the dangers - in 2008, Atlanta came just 90 days from running completely out of drinking water - and the opportunities, such as advances in rainwater harvesting and businesses that are making huge breakthroughs in water productivity, The Big Thirst will forever change the way we think about water, our crucial relationship to it, and the creativity we can bring to ensuring we always have plenty of it.
