This article examines Sibu Oromo environmental ethic and investigates Sibu Oromo attitudes towards the environment. This study relies on literature review, interviews and personal observation. Data collected through both primary and secondary sources indicated that the Sibu Oromo attitudes towards the environment have been mainly challenged by foreign religions and degeneration of Waqeffannaa and Gadaa system. Being influenced by these factors, Sibu Oromo have been caught in dilemma: the old world and new world. Revitalization of Gadaa system in general and Waaqeffannaa in specific is a necessary condition for the promotion of interconnectedness and interrelatedness between human beings, non-human beings and the natural environment.
