As environmental degradation continues to worsen, the idea of ecocide is gaining attention as a major global security concern. This paper argues that ecocide, defined as severe, widespread, or long-term damage to the environment, presents a significant threat to global stability and should be recognized as an international crime. The paper explores the history of discussions around ecocide, tracing its connections to the concept of genocide and earlier attempts to criminalize environmental destruction in international law. It then examines current efforts to incorporate ecocide into international law, focusing on the proposal to add it as a fifth crime to the Rome Statute. While acknowledging the potential benefits of this step, the paper also critically evaluates the challenges involved, including the International Criminal Court's limited membership and the difficulties in agreeing on a universal definition. By looking at examples such as the Vietnam War, the draining of the Mesopotamian Marshes, and the destruction of the Nova Kakhovka dam, this analysis shows how ecocide contributes to humanitarian crises, resource scarcity, and regional instability. The paper concludes that recognizing ecocide as an international crime, whether through amending the Rome Statute or establishing a specialized environmental court, is crucial for deterring widespread environmental destruction and promoting global environmental justice, though achieving this requires significant international cooperation, especially from major global powers.
