NEW YORK TIMES BESTSELLER Finalist for the Banff Mountain Book Competition in Environmental Literature Longlisted for the Andrew Carnegie Medal for Excellence in Nonfiction A Hill Times Top 100 Best Book of 2025 From the celebrated writer, observer and naturalist Robert Macfarlane comes a brilliant, perspective-shifting new book, which answers a resounding "yes" to the question of its title. At the heart of Is a River Alive? is a single, transformative idea: that rivers are not mere matter for human use, but living beings, who should be recognized as such in both imagination and law. Macfarlane takes the reader on a mind-expanding global journey into the history, futures, people and places of the ancient, urgent concept. Around the world, rivers are dying from pollution, drought and damming. But a powerful movement is also underway to recognize the lives and the rights of rivers, and to re-animate our relationships with these vast, mysterious presences whose landscapes we share. The young "rights of nature" movement has lit up activists, artists, law-makers and politicians across six continents—and become the focus for revolutionary thinking about rivers in particular. The book flows like water, from the mountains to the sea, over three major journeys. The first is to northern Ecuador, where a miraculous cloud-forest and its rivers are threatened with destruction by Canadian gold-mining. The second is to the wounded rivers, creeks and lagoons of southern India, where a desperate battle to save the lives of these waterbodies is underway. The third is to northeastern Quebec, where a spectacular wild river—the Mutehekau or Magpie—is being defended from death by damming in a river-rights campaign led by an extraordinary Innu poet and leader called Rita Mestokosho. Is A River Alive? is at once a literary work of art, a rallying cry and a catalyst for change. It is a book that will open hearts, spark debates and challenge perspectives. A clarion call to re-centre rivers in our stories, law and politics, it invites us to radically re-imagine not only rivers but life itself. At the heart of this vital, beautiful book is the recognition that our fate flows with that of rivers—and always has.
