This paper introduces a special issue focusing on the intersection of genocide and ecocide, exploring the growing field of environmental genocide studies within Holocaust research. It highlights the increasing importance of ecocritical and zoocritical perspectives in understanding the Holocaust and related events. The introduction delineates the core themes examined in the issue’s six articles, providing summaries of each contribution. Furthermore, it considers potential future directions for this transdisciplinary field, emphasizing the need to move beyond anthropocentric views and incorporate non-human perspectives in the study of mass violence and environmental destruction. The paper also addresses the debates and resistance encountered when connecting the Holocaust with ecological concerns, particularly regarding potential trivialization of human suffering. Ultimately, it argues for the value of this interdisciplinary approach in gaining new insights into the interconnectedness of human and non-human experiences during periods of genocide and ecocide.
