Braiding Sweetgrass is a book about questions of nature. It includes Native American legends. It addresses the reciprocal relationships among all beings. It explores how the tools of science relate to indigenous wisdom. The book’s central argument is that instead of ignoring or dominating the rest of the living world, we can live in harmony with it. Native American tribes have long known this to be true. Scientific knowledge is intersecting with (or awakening to) indigenous wisdom. This return to ecological consciousness cannot come too soon.
