This study aims to analyse ecocides as a gross violation of human rights through a case study of river pollution conducted by palm oil companies in Indonesia. This article is methodologically distinctive from doctrinal legal research, primarily through a literature review. There are three main reasons for incorporating environmental concerns as an extraordinary crime of ecocide into serious human rights violations, especially those committed by several palm oil companies in Indonesia, namely: The quality of the Environment is the essence of human life that complements human dignity; environmental concerns and crimes in the tradition of extraordinary crimes are a response to the inability of national and even international environmental laws; and ensure restitution, rehabilitation and compensation to all victims of ecocide crime.
