Creative writers in Nigeria often follow the trend of events in their society and respond to happenings through their art. One such event is the Niger-Delta crisis. The novel, being a tool for social investigation, continues to reveal deep insights into the moving spirit of these crises than any historical or political document treating the same subject. This is a view well expressed by the foremost Kenyan writer, Ngugi Wa Thiong’o.  However, despite the tendency of Niger Delta writers to dwell extensively on environmental issues in their works, this work argues that environmental matters cannot be the sole issues pursued in Niger-Delta literature. Using the ecocritical and sociological theory, this study explores multifaceted issues presented in Niger-Delta Literature, such as human greed, selfishness, ignorance and several others, with the sole objective of proving that no writer or group of writers can foreground just one thematic preoccupation in their work, no matter how laudable such a focus might be.
