The author of the Pulitzer Prize finalist The Forest Unseen visits with nature's most magnificent networkers -- trees "Both a love song to trees, an exploration of their biology, and a wonderfully philosophical analysis of their role they play in human history and in modern culture." - Science Friday WINNER OF THE 2018 JOHN BURROUGHS MEDAL FOR OUTSTANDING NATURAL HISTORY WRITING David Haskell has won acclaim for eloquent writing and deep engagement with the natural world. Now, he brings his powers of observation to the biological networks that surround all species, including humans. Haskell repeatedly visits a dozen trees, exploring connections with people, microbes, fungi, and other plants and animals. He takes us to trees in cities (from Manhattan to Jerusalem), forests (Amazonian, North American, and boreal) and areas on the front lines of environmental change (eroding coastlines, burned mountainsides, and war zones.) In each place he shows how human history, ecology, and well-being are intimately intertwined with the lives of trees. Scientific, lyrical, and contemplative, Haskell reveals the biological connections that underpin all life. In a world beset by barriers, he reminds us that life's substance and beauty emerge from relationship and interdependence.
