At its heart 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. Inspired by the activists, artists and lawmakers of the young ‘Rights of Nature’ movement, Macfarlane takes the reader on an exhilarating exploration of the past, present and futures of this ancient, urgent concept. Passionate, immersive and revelatory, Is a River Alive? is a book that will open hearts, spark debates and challenge perspectives. Lit throughout by other minds and voices, it invites us radically to reimagine not only rivers but also life itself. At the centre of this vital, beautiful book is the recognition that our fate flows with that of rivers – and always has.
