World of Rot takes readers on a deep dive into the process of decay, from the science behind it to an up-close and personal look at the organisms that do the dirty work to make our planet livable.

With a touch of humor and quirky full-color illustrations, kids will learn about the life-recycling system happening all around us-in the sea, in the soil, and even inside our own bodies. Profiles of decomposers such as hungry fungi and familiar worms, poop-slurping butterflies, and slimy banana slugs offer something to pique the curiosity of every kid. Readers will also learn the heroic role decomposers might play in fighting climate change and eating plastic.
