Water, air, sunlight, plants . . . we need these elements to live in this world. But does the world need us? And what would happen to the world if humans were gone? This is the premise of a thought-provoking picture book from John Coy. His insightful text explores how nature would reclaim the planet, accompanied by Natalie Capannelli''s gorgeous watercolor illustrations. Back matter gives further context and discusses what kids (and all of us) can do to truly help our planet.
