“Sutton’s spectacular illustrations . . . take the concept of ‘many’ to the extreme. . . . Davies has a keen sense of how to represent science for beginners.” —The Horn Book (starred review)The more we study the world around us, the more living things we discover every day. The planet is full of millions of species of plants, birds, animals, and microbes, and every single one—including us—is part of a big, beautiful, complicated pattern. When humans interfere with this pattern, by polluting the air and oceans or cutting down too many forests, animals and plants begin to disappear. What sort of world would it be if Earth went from having many types of living things to having just one? Now in paperback, this beautiful follow-up to the award-winning Tiny Creatures: The World of Microbes delivers an inspiring look at the extraordinary diversity of Earth’s inhabitants—and the importance of their preservation.
