This Winter I taught environmental anthropology again for the first time in six years. Relevant advocacy and applied works are now being rapidly generated through the interdisciplinary fields of human ecology and political ecology (our own Barbara Johnston's work being quite notable). Auditing my class was Lynn Oliphant, a renowned ecologist, as well as winner of my university's Master Teacher Award. In effect Lynne helped to teach the course through his discussions. At the end, he provided a guest lecture that served as a capstone to the class. In the interest of interdisciplinary discussion on this important topic, I invited him to share those thoughts with the readers of Practicing Anthropology.- Editor
