While our politicians argue, the truth is that climate change is already here. Nobody knows this better than Indigenous peoples who, having developed an intimate relationship with ecosystems over generations, have observed these changes for decades. For them, climate change is not an abstract concept or policy issue, but the reality of daily life.After two decades of working with indigenous communities, Gleb Raygorodetsky shows how these communities are actually islands of biological and cultural diversity in the ever-rising sea of development and urbanization. They are an "archipelago of hope" as we enter the Anthropocene, for here lies humankind's best chance to remember our roots and how to take care of the Earth.We meet the Skolt Sami of Finland, the Nenets and Altai of Russia, the Sapara of Ecuador, the Karen of Myanmar, and the Tla-o-qui-aht of Canada. Intimate portraits of these men and women, youth and elders, emerge against the backdrop of their traditional practices on land and water. Though there are brutal realities—pollution, corruption, forced assimilation—Raygorodetsky's prose resonates with the positive, the adaptive, the spiritual—and hope.
