We all do it. We usually don't like to talk about it, but going to the toilet is a natural and necessary part of our lives.This series takes readers (Ages 8-12) on a historical journey, examining how people coped in the past and how they developed ingenious ways to make life safer and less unpleasant. Each book features full-color cartoon-style illustrations and hilarious speech bubbles to heighten interest, making the series attractive even to reluctant readers.We couldn't live without poop because there are some parts of our food that contain no nutrients that can be used by our bodies for energy, growth or health, and those parts have to be ejected. But poop can also be used to power our cars, heat our homes and help grow our crops. Learn why and how animals and people produce poop, and about the many marvellous uses for this misunderstood substance.
