This paper proposes that the cultural understanding of nature under the Modern paradigm is inadequate. I propose that the result of this deficient representation of nature has been the degradation of the environment and our culture. The degradation of the environment is well studied, but I suggest that our culture is degraded by limited contact with nature and the loss of nature as a potential source of value and source of meaning. This paper explores the writings of several philosophers and social critics who support this supposition. In order to develop a more representative understanding of nature this paper suggests that landscape architects study Aldo Leopold's theory of landscape aesthetics. Leopold's concept of experiential knowledge is discussed as a means of offering our culture a deeper appreciation of nature, but also as a means for landscape architects to improve their own education and design process. Based on the experiences of flyfishers this paper suggests that the practice of Leopold's landscape aesthetic is both possible and fulfilling. / Master of Landscape Architecture

Esta pesquisa, inserida na linha de pesquisa Historia, Filosofia e Ensino de Evolucao e Ecologia, trata sobre a Estetica, procurando verificar as possiveis contribuicoes desse referencial teorico para o estudo do meio em Biologia, nomeadamente para aulas de campo voltadas para o Ensino Superior em cursos de Ciencias Biologicas. A Estetica descrita por Charles Sanders Peirce (1839-1914), nao limita-se somente ao entendimento da Estetica como uma ciencia do belo. A Estetica peirceana possui um carater mais abrangente, que reside na essencia de qualquer objeto apreendido pela experiencia; o admiravel que desperta a atencao, seja o objeto considerado belo ou nao pelas convencoes. Nas ideias de Aldo Leopold (1887-1948), que tratam de uma Estetica voltada para a conservacao dos seres vivos, verifica-se um dialogo com a Teoria de Peirce por meio das cinco categorias da Estetica da Conservacao: os trofeus, o isolamento na natureza, ar livre e mudanca de panorama, percepcao e sentido da administracao cuidadosa. Considerando essas categorias, foi proposta uma sequencia didatica tendo a trilha realizada pelo naturalista Auguste de Saint-Hilaire (1779-1853) na Serra da Canastra (MG) como eixo norteador. A proposta com abordagem interdisciplinar favorece o desenvolvimento das aulas de campo a partir de elementos filosoficos e historicos, permitindo que os alunos revisitem os ambientes descritos por Saint-Hilaire de maneira mais motivadora e contextualizada / This proposal is inserted in the research line \"History, Theory and Teaching of Comparative Biology\" and will work with Aesthetics seeking to verify the possible contributions of this theoretical reference for the study of the environment in Biology, particularly in field classes focused on Higher Education in Biology Graduation. The Aesthetics, described by Charles Sanders Peirce (1839-1914), is not limited to a science of the beautiful. Aesthetics has a more comprehensive character and resides in the essence of any object apprehended in our experience that arouses our attention, be it considered beautiful or not by the conventions. It it something that we consider \"admirable\". We found in the ideas of Aldo Leopold (1887-1948), that deals with an Aesthetics focused on the conservation of living beings, a dialogue with Peirce\'s Theory. Leopold (1949) proposes five categories of Conservation Aesthetics: trophy, isolation, change of scene, perception and husbandry. Based on these categories it was proposed a Didactic Sequence having the trail made by the naturalist Auguste de Saint- Hilaire (1779-1853) in Serra da Canastra as a background. We chose to adopt an interdisciplinary approach, and while the students revisit the points visited by Saint- Hilaire, field classes are developed with the aim of investigating the environment as the naturalist himself did

270 pages / I theorize and offer some evidence that humans inadvertently risk exacerbating the loss of maintenance-dependent species on private land by using species-based land-use regulation to seek other benefits. Drawing evidence primarily from the US, I argue that such regulation poses a risk to maintenance-dependent species, that humans routinely disregard this risk, and that this disregard widely serves to defend the power of individuals and organizations to use such regulation to seek other benefits. I suggest this implies that with constraints on public funding, humans might improve the survival of some species by clarifying the purpose of such regulation and considering openly refraining from such regulation for some species. I also suggest such change might depend on articulating the issue as whether the survival of a species could ever depend on individuals having a right to conserve or maintain it without selectively incurring harm from regulation intended to save it.

The Rio Gavilan watershed, located in Mexico 's northern Sierra Madre Occidental , has significance in conservation history. Upon visiting the remote, largely un­developed watershed during two hunting trips in the 1930s, renowned conservationist Aldo Leopold thought it was the best picture of land health he had seen. His main indicators of healthy land were slow water runoff rates regulating erosion and historical predator-prey relationships. The visits confirmed Leopold's concept of land health, inspired many of his essays, and helped shape his land ethic. Leopold proposed the area as a control site to research healthy land throughout North America . The proposal never went forward and the area has since been more intensively logged and grazed. This dissertation research used extensive literature review, archives, oral histories, citizen surveys, and rapid assessment of forest, rangeland, riparian, and socioeconomic health to assess impacts of past cultures and update the area's land health status. Projects that could restore land health, such as linked eco-tourism, forest density reduction, and rotational grazing, were assessed for feasibility. Recent critiques of Leopold's land ethic were also reviewed. Results indicate most pre-1940s impacts were light, current land health status is moderate, and local interest exists in restoring land health. Many fish and wildlife populations are reduced, temporarily stabilized, but still at risk. Soil and riverbed erosion, service sector economics, and (at some ridge-top sites) forest density are the land health indicators in worst condition. Land health restoration projects are feasible.

Deeply influenced by emotional, ethical, and ecological principles, John Steinbeck developed a holistic ideology to describe and analyze the relationships among individuals, society, and the more-than-human world. Although he explored environmental issues with ecological insight and philosophical contemplation that placed him well beyond his literary and scientific contemporaries, Steinbeck’s contributions to modern ecological inquiry and environmental thought have received only intermittent attention from literary scholars. Throughout his writing, Steinbeck develops a view of intellectual holism that encourages (perhaps even enables) us to dovetail science and ethics as we attempt to construct a new environmental paradigm. Viewing the world through his holistic lens, Steinbeck was able to see the global ecosystem, local environments, human communities, and even minute tide pools as objects of scientific and artistic inquiry. Specifically, it is my contention that the American environmental movement owes a greater debt to John Steinbeck than it realizes. In short, John Steinbeck made significant contributions to the growing awareness of human-nature interconnectedness and the parallels between social ills and ecological ailments. Yet, for whatever reasons Steinbeck is not granted a position of honor alongside the other giants of American environmental thought. Now witnessing the full blossoming of 21st century environmentalism, it is useful to cast a reflexive eye upon our ideological forebears with the intent to better understand the genealogy of the American environmental movement. Doing so will not only provide a richer and fuller family tree, but will also promote additional flourishing of new approaches to solving ongoing environmental troubles. / Master of Arts
