This paper examines the concept of cleanliness and issues pertaining to the environment in some of the major world religions. The authors explore the universal values as transpired in the holy scriptures of the three Abrahamic traditions dealing with the concept of cleanliness and issues of ecological systems, such as environmental protection. A qualitative methodology that covers content and textual analyses on the Holy Scriptures, views of scholars and related materials are employed in this paper. The research reveals that there are agreements on certain issues, such as the triad of position - man, environment and God - shared by the three religions in their approaches toward issues of the environment, specifically and in general.
