Abstract: Environmental education and environmental advocacy have a contentious relationship. In this article, the author argues that there will always be uncertainty about educationally appropriate responses to controversial issues. Although uncertainty is inherent in this task, the choices are not dichotomous. The author also argues that education suggests a fluidity of meaning that shifts across a range of contexts, and what needs to be done will be found on a case-by-case and context-by-context basis in a mediated and negotiated third space. Some tentative guide-posts are offered.
