In this paper, I plan to explore the idea of the human body as an ecology and as an extension of the physical-social world commonly perceived as external to the human body. Most ecocritical studies focus on the corruption, exploitation and domination of the physical world by human beings and seek to generate solutions by developing thoughts around biocentrism or biodiversity, which pursues a balance in the world. This paper, however, seeks to undertake an ecocritical reading based on the view that the most immediate physical environment that the human subject relates with is the body. The paper also thinks of the body not only as an environment, but also as an extension of the number of living and nonliving bodies with which every human body is either in interaction or conflict. To engage in this postcolonial ecocritical reading of the body as ecology, my case study is Chris Abani’s Graceland. This is a novel that captures life in the Nigeria of military dictatorship with obvious interest in the way the squalid Nigerian slum environment mirrors both the state of the nation and the precarious state of citizenship. In doing this, Abani foregrounds the human body as subjected to the kind of pollution, exploitation and wastage that environmentalist rhetoric associates with land, flora and fauna, bodies of water and urban environments. The discussion will draw theoretically on Felix Guattari’s idea of three ecologies and Merleau-Ponty’s phenomenology of the body to be able to conceptualize body-world and body-mind relations.
