This study explores the concept of ecocide and its recognition within international law. In light of technological advancements and their widespread destructive impact on the environment, alongside developments in international criminal and environmental law, it is increasingly necessary to analyze ecocide and the responses of the global community. The main research question focuses on clarifying the precise definition of ecocide and tracing the evolution of international approaches to it. In particular, the study examines whether ecocide should be defined from an anthropocentric perspective, prioritizing human interests, or an ecosystem-centric perspective, prioritizing the integrity of ecological systems. Findings suggest that adopting an ecosystem-centric definition can provide more effective environmental protection. Using a descriptive-analytical and library-based methodology, this article also examines the historical development and codification of ecocide to assess its impact on the evolution of international law in this area. The research outcomes may inform the creation of more comprehensive legal frameworks to prevent severe environmental degradation.
