It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

    A saga of bombs, ice ages and civilisations falling. Of ancient hunger, modern sicknesses and gastronomic delight. It features poison gas, climate collapse and a mind-blowing explanation of how rain is formed. For too long, we've not only neglected the land beneath us, we've squandered and debased it, by over-clearing, over-grazing and over-ploughing. But if we want our food to nourish us, and to ensure our planet's long-term health, we need to understand how soil works - how it's made, how it's lost, and how it can be repaired. In this ode to the thin veneer of Earth that gifts us life, commentator and farmer Matthew Evans shows us that what we do in our backyards, on our farms, and what we put on our dinner tables really matters, and can be a source of hope.

    A lush treasury of 19 fairy tales that generations of children have grown up on, lushly illustrated by Diane Goode.

    On a cold January day in 2017, nearly two months before her due date, Nile hippopotamus Bibi gave her keepers at the Cincinnati Zoo & Botanical Garden a big (little) surprise - a tiny newborn hippo, no bigger than a football.  The first premature hippo born and raised in captivity, baby Fiona was an underdog from the start:  she couldn't nurse, she couldn't stay hydrated, and she wasn't thriving. But the staff at the zoo knew they could save her.  It would take creative thinking and teamwork. They would have to study the makeup of hippo milk for the first time ever and reach out to medical colleagues, including a team at the local Children's Hospital with superior vein-finding skills,  to ensure that Fiona would begin to gain weight and become healthy. When Fiona began to thrive, her star began to rise, and soon she became an internet sensation, her picture and videos garnering thousands and thousands of likes and fans on Instagram and Facebook.  Now a Fiona appearance at the Zoo mimics a Beatles concert.  What made this little, now big, hippo such a big hit with people all over the world?  And what's in store for her and her family in the future?
