A deep dive into deep time as well as a political manifesto advocating for a new coalition with beavers.

"Water is life, and right now, in the hydrographic networks simplified and accelerated by modern waterworks, life escapes us oceanward," writes author Baptiste Morizot, a leading philosopher of French environmental thought. Moving from this alarming observation, he reveals that a small world-making creature, the first creator of megabasins, has been present in our rivers for 8 million years and is working to save them. What creature is it? Why, you guessed it—the beaver! This book is a deep dive into deep time—"river time"—as well as a political manifesto advocating for a new coalition with beavers, for the good of one and all: especially us humans.
