Excavating the dirty truths of human waste (and its disposal) through history. Hold your nose and dive into the smelly, but surprisingly fascinating world of sewers! From the mighty Cloaca Maxima of Ancient Rome to the revolting, waste-filled streets of the Middle Ages, and on to the ingenious pipes and tunnels of Joseph Bazalgette’s Great London Sewer, this book uncovers the gross—and great—history of how humans have dealt with their dirty business. With bright, hilarious, detail-packed illustrations by Rob Flowers, Flush It Down is packed with fun facts, weird tales, and thought-provoking discussions around the problems of human waste and how we can deal with the challenges facing us today. It’s a wild, wacky ride through the underground—no rubber boots required! and an engaging tie-in to biology and natural sciences curriculums.
