From the bestselling author of The Hidden Life of Trees. Did you know that trees can influence the rotation of the earth? Or that wolves can alter the course of a river? Or that earthworms control wild boar populations? The natural world is a web of intricate connections, many of which go unnoticed by humans. But it is these connections that maintain nature's finely balanced equilibrium. Drawing on the latest scientific discoveries and decades of experience as a forester, Peter Wohlleben shows us how different animals, plants, rivers, rocks and weather systems cooperate, and what's at stake when these delicate systems are unbalanced.
