When The Earth Was Green

A gorgeously composed narrative nonfiction book about the longstanding relationship between prehistoric plants and life on Earth.

> We often retell the history of life on Earth as a series of great moments in which fascinating animal life springs forth, all the while forgetting the plants that made these moments possible. But we can't understand our own history without them. Or, our future. Dinosaurs, saber-toothed cats, and all mammals would be nothing without the efforts of their leafy counterparts. Even humans would likely not exist had plants not taken root to sow the land for our amphibious ancestors.

Using the same scientifically-informed narrative technique that readers loved in the award-winning The Last Days of the Dinosaurs, in When the Earth Was Green, Riley Black brings readers back in time to prehistoric seas, swamps, forests, and savannas where critical moments in plant evolution unfolded. Each chapter stars plants and animals alike, underscoring how the interactions between species have helped shape the world we call home. As the chapters move upwards in time, Black guides readers along the burgeoning trunk of the Tree of Life, stopping to appreciate branches of an evolutionary story that links the world we know with one we can only just perceive now through the silent stone, from ancient roots to the present.
