With the world becoming ever more complex, comms pro Richard Purnell and science writer Dr Alexis Willett take a leisurely look at how humans are getting on, through the lens of the four classical elements; water, earth, air and fire. Just two people having a chat. In this first series about water, they explore everything from the pleasures of spa towns and the humble bath, through to power grabs in the Middle East, hovercrafts and murder mysteries. If you want a fresh way of looking at the world, without the usual predictable points of view, Elemental Conversations is for you.
