Advances in Nursing Science: January 2006 - Volume 29 - Issue 1 - p 43-54 Buy Abstract Current epistemological foundations of nursing theory incorporate minimal ecology theory. The purpose of this article is to present a nursing ecological theory with a goal to broaden current nursing perspectives by incorporating expanded concepts of global ecosystems, communities, and interrelationships derived from ecological sciences. A theory derivation process is utilized, and a nursing ecological model is proposed. Nurses face a challenge to translate global environment concern and ecological beliefs into professional activities. Elucidating a nursing ecological theory may guide our profession toward new directions in holistic care and will be good for the care of our patients, profession, and the Earth. © 2006 Lippincott Williams & Wilkins, Inc.
