Crazy but true, life on Earth can't exist without poop! Starting with human sewage then moving on to animal poop, this surprisingly charming lift-the-flap book explores what happens when we flush, what animal toilets look like, why animals don't need to flush and just how important poop is - for a myriad of fascinating (and sometimes yucky) reasons.

Clamber up branches and peek through leaves to discover the wonderful jobs trees do, from cleaning our air and keeping us cool to protecting our planet and providing homes for all kinds of wildlife.
