In response to the damage caused by centuries of colonial ravaging and the current ecological, political and social crises, the leading Indigenous thinker and activist Ailton Krenak warns against the power of corporate capitalism and its destructive impact. Capitalism encroaches on every corner of the planet and orients us toward a future of promised progress, achievement and growth, but this future doesn't exist - we just imagine it. This orientation to the future also blinds us to what exists around us, to the plants and animals with which we share the Earth and to the rivers that flow through our lands. Rivers are not just resources to be exploited by us or channels to carry away our waste, they are beings that connect us with our past. If there is a future to imagine, it is ancestral, since it is already present in the here and now and in that which exists around us, in the rivers and mountains and trees that are our kin. In a spoken language that has the mark of ancestral oral wisdom, Krenak offers a new perspective that challenges and disrupts some of the assumptions that underpin Western attitudes and mentalities. His work will be of great interest to anyone concerned about the climate crisis and the worsening plight of our planet.
