This paper examines the environmental vision embedded in the writings and activism of Ken Saro-Wiwa and argues that his works articulate a poetics of the land that foregrounds ecological justice, ethical reorientation, and democratic responsibility. Drawing on insights from ecocriticism and environmental humanities, the study analyzes Saro-Wiwa‘s memoirs On a Darkling Plain: An Account of the Nigerian Civil War and A Month and a Day: A Detention Diary to explore the intersections of environmental degradation, political marginalization, and environmental racism in the Niger Delta. The paper contends that Saro-Wiwa‘s narratives function not merely as autobiographical records but as ethical interventions that challenge exploitative relations between humans, the state, multinational corporations, and the natural environment. Through his literary and political engagement, Saro-Wiwa articulates an ecological consciousness that calls for sustainable development, environmental responsibility, and justice for marginalized communities. The study concludes that his writings remain a significant contribution to African ecocritical discourse and offer an enduring framework for understanding the relationship between literature, activism, and environmental ethics in contemporary Nigeria
