Humanity is facing major existential challenges, climate change and armed conflict are amplifying these pressures. This paper analyzes the increasing importance of recognizing ecocide as a global crime due to growing scientific evidence of Earth reaching critical “tipping points” and “planetary limits.” It examines the potential of including ecocide in national laws as a tool to combat environmental destruction and promote sustainability, while also considering the need for a clear definition, consistent application, and a unified international framework, potentially through the International Criminal Court.
