The study explores how The Hungry Tide by Amitav Ghosh attempts to rebuild the ecological and subaltern dialectic in postcolonial India. It will examine the statement of Ghosh regarding the massacre of Morichjap and the displacement of refugees and deteriorating ecosystem of Sundarbans as a reconstructing element of environmental justice with the help of an interpretative qualitative framework through the prism of subaltern theory (Spivak, Gramsci) and postcolonial ecocriticism (Nixon, Chakrabarty). The study concludes that the novel shifts the ecological debate into an ethical struggle script that places the oppressed groups in the conservationist agenda in the limelight of narration. The reading of The Hungry Tide as ecological fiction and subaltern testimony allows the study to enter into the current discussions in fields of environmental humanities and South Asian literary studies by predicting the inseparability of the ecological, the power, and voice in the context of postcolonial narratives.
