Anthropologists have mediated between discriminated communities and outsiders, helping to influence public opinion through advocacy work. But can anthropological advocacy be applied to the case of violence against nonhumans? Ethical inquiries in anthropology also engage with the manifold ways through which human and nonhuman lives are entangled and emplaced within wider ecological relationships, converging in the so-called multispecies ethnography, but failing to account for exploitation. Reflecting on this omission, this article discusses the applicability of engaged anthropology to the range of issues from the use of nonhumans in medical experimentation and food production industry, to habitat destruction, and in broader contexts involving violence against nonhumans. Concluding that the existing forms of anthropological engagement are inadequate in dealing with the massive scale of nonhuman abuse, this article will suggest directions for a radical anthropology that engages with deep ecology, animal rights, animal welfare, and ecological justice.
