This work documents the various ethical dilemmas that confront anthropologists, and researchers in general, when investigating Amerindian communities. The contributions to this volume explore the ramifications of reporting and non-reporting instances of environmental degradation and warfare among Amerindians.Collectively, the contributions in this volume, which extend across the disciplines of archaeology, anthropology, ethnohistory, ethnic studies, philosophy, and medicine, argue that the non-reporting of environmental mismanagement and violence in Amerindian communities generally harms not only the field of anthropology but the Amerindian populations themselves.
