For more than 20 years, British author and Cambridge University professor Robert Macfarlane has garnered international acclaim for his writings on nature and our relationships to it, from awe-inspiring wonder and life-giving sustenance to relentless extraction and exploitation. For his book, “Is a River Alive?”, Macfarlane explored the idea of rivers as animate beings, a concept that is connected to the Rights of Nature movement that has spurred a novel legal framework to protect imperiled waterways, animals and ecosystems around the world.

To find out, Macfarlane embarked on a journey that spanned continents and topographies. He trekked through a cloud forest in Ecuador, visited dying and polluted waterways in southeastern India and kayaked down a river in northeastern Canada that was granted legal personhood in 2021 to save it from being dammed. Along the way, Macfarlane introduces us to the people fighting to defend these rivers, creeks and basins while bearing witness to the assaults and threats the waterways constantly face.

Macfarlane joined us on June 11, 2025 to discuss “Is A River Alive?” and the ideas it explores.
