Readers will be surprised to find out that their poop is good for building things. They’ll learn how animals use poop to construct nests, homes, and even fences. People mold it into bricks for houses and plop it on fences for support. It’s biodegradable, environmentally friendly, and can add a bit of spice to any home construction project.
