Аннотация:The ecological crisis is one of the greatest challenges humanity faces in this century. Climate change and ecosystem degradation pose real threats to the future of life on the planet. However, despite global security and survival being key themes in the study of international relations, environmental issues have remained on the sidelines of the discipline in recent decades. This reality seems to be changing with the publication of an increasing number of works that seek to rethink the discipline and the practice of world politics through the lens of ecology. These works call for a political transformation to address the crisis and challenge the traditional institutionalist approach dominant in the literature, which focuses on the analysis of intergovernmental cooperation and the effectiveness of international environmental institutions, such as the United Nations (UN) climate and biodiversity regimes.
