This dissertation analyzes the way in which leaders of certain Taiwanese Buddhist organizations associated with a strand of Buddhist modernism called "humanistic Buddhism" use discourse and rhetoric to make environmentalism meaningful to their members. It begins with an assessment of the field of religion and ecology, situating it in the context of secular environmental ethics. It identifies rhetoric and discourse as important but under acknowledged elements in literature on environmental ethics, both religious and secular, and relates this lack of attention to rhetoric to the presence of a problematic gap between environmental ethics theory and environmentalist practice. This dissertation develops a methodology of rhetorical analysis that seeks to assess how rhetoric contributes to alleviating this gap in religious environmentalism. In particular, this dissertation analyzes the development of environmentalism as a major element of humanistic Buddhist groups in Taiwan and seeks to show that a rhetorical analysis helps demonstrate how these organizations have sought to make environmentalism a meaningful subject of contemporary Buddhist religiosity. This dissertation will present an extended analysis of the concept of "spiritual environmentalism," a term developed and promoted by the late Ven. Shengyan (1930-2009), founder of the Taiwanese Buddhist organization Dharma Drum Mountain. Furthermore, this dissertation suggests that the rhetorical methodology proposed herein offers offers a direction for scholars to more effectively engage with religion and ecology in ways that address both descriptive/analytic approaches and constructive engagements with various forms of religious environmentalism.

The Committee on Rare and Endangered Wildlife Species (CREWS) of the U.S. Fish and Wildlife Service (FWS) made important and lasting contributions to one of the most significant pieces of environmental legislation in U.S. history: the Endangered Species Act of 1973 (ESA). CREWS was a prominent science-advisory body within the U.S. Department of the Interior (DOI) in the 1960s and 1970s, responsible for advising on the development of federal endangered-wildlife policy. The Committee took full advantage of its scientific and political authority by identifying a particular object of conservation--used in the development of the first U.S. list of endangered species--and establishing captive breeding as a primary conservation practice, both of which were written into the ESA and are employed in endangered-species listing and recovery to this day. Despite these important contributions to federal endangered-species practice and policy, CREWS has received little attention from historians of science or policy scholars. This dissertation is an empirical history of CREWS that draws on primary sources from the Smithsonian Institution (SI) Archives and a detailed analysis of the U.S. congressional record. The SI sources (including the records of the Bird and Mammal Laboratory, an FWS staffed research group stationed at the Smithsonian Institution) reveal the technical and political details of CREWS's advisory work. The congressional record provides evidence showing significant contributions of CREWS and its advisors and supervisors to the legislative process that resulted in the inclusion of key CREWS-inspired concepts and practices in the ESA. The foundational concepts and practices of the CREWS's research program drew from a number of areas currently of interest to several sub-disciplines that investigate the complex relationship between science and society. Among them are migratory bird conservation, systematics inspired by the Evolutionary Synthesis, species-focused ecology, captive breeding, reintroduction, and species transplantation. The following pages describe the role played by CREWS in drawing these various threads together and codifying them as endangered-species policy in the ESA.
