Clean
Steven Johnson reveals just how much we owe to the 19th century pioneers - the risks they took and the the engineering they implemented to clean up our water sources.
Steven Johnson uncovers how βthe conflict between man and bacteriaβ has had far reaching consequences for public health. In the story of clean he reveals just how much we owe to the nineteenth century pioneers who took extraordinary risks to clean up our water sources, and implemented extraordinary feats of engineering to remove sewage from our streets. He also reminds us that the battle isnβt over when he tells us about the application of cutting edge technologies that have led to the development of a new kind of toilet.
As part of the Richer World season Steven Johnson, the bestselling science writer, reads from his latest book How We Got to Now where he examines inventive minds, brilliant mistakes and the surprising connections that gave us the everyday objects that have made the modern world.
