Many examples show that our environmental education practice is disappointed. And this aspect of education has not been incorporated in our formal educational system even though every educator and most of our citizens realize the importance of developing student sense of protecting our environment. It is time to reflect what to do with environmental education. In theoretical aspect of environmental education, we need to combine humanistic experience and knowledge of natural sciences in order to establish ecological sustainable world view. Three scholars were mentioned in this paper-C. A. Bowers, D. W. Orr, and J. A. Palmer. Their discussions and actual practice in the field of environmental education are explored. Palmer gives a plan to advocate environmental education. He discusses three elements that include knowledge and understanding, ethical element, and aesthetic element. There is one basic formative influence that incorporates those three. Orr develops a long-term curriculum design and leads to construct a renowned building located in Oberlin College, Ohio. This is a good teaching and learning example for teachers and students in environmental education. Bowers criticizes and argues that besides modernity and modern technology, modern consumerism has created more hazard materials and ecological dangerous situation than other means such as new technological developments. He also discusses principles and methods on teaching and learning in environmental education.
