Holmes Rolston has defended certain forms of hunting and meat eating when these activities are seen as natural participation in the food chains in which we evolved. Ned Hettinger has suggested that some of Rolston’s principles that govern our interactions with plants and animals might appear to be inconsistent with Rolston’s defense of these activities. Hettinger attempts to show that they are not. We argue that Rolston’s principles are not consistent with hunting, given Hettinger’s modifications. In his defense of Rolston, (...) Hettinger has challenged animal welfare ethicists to show that they can value animal predation while consistently condemning human hunting. We answer that hunting and meat eating by humans are “cultural” rather than “natural” activities. (shrink)

Are ecosystems morally considerable-that is, do we owe it to them to protect their “interests”? Many environmental ethicists, impressed by the way that individual nonsentient organisms such as plants tenaciously pursue their own biological goals, have concluded that we should extend moral considerability far enough to include such organisms. There is a pitfall in the ecosystem-to-organism analogy, however. We must distinguish a system’s genuine goals from the incidental effects, or byproducts, of the behavior of that system’s parts. Goals seem capable (...) of giving rise to interests; byproducts do not. It is hard to see how whole ecosystems can be genuinely goal-directed unless group selection occurs at the community level. Currently, mainstream ecological and evolutionary theory is individualistic. From such a theory it follows that the apparent goals of ecosystems are mere byproducts and, as such, cannot ground moral considerability. (shrink)

Discusses managing the environment from philosophical, scientific, and political perspectives.

This introduction to biological conservation assesses the value judgments at the heart of conservation. The author elaborates on such questions as: how much habitat does an endangered species require?; does this particular species deserve to be saved?; who will pay for its upkeep?; and much more.

Traditional ecocentric ethics relies on an ecology that emphasizes the stability and integrity of ecosystems. Numerous ecologists now focus on natural systems that are less clearly characterized by these properties. We use the elimination and restoration of wolves in Yellowstone to illustrate troubles for traditional ecocentric ethics caused by ecological models emphasizing instability in natural systems. We identify several other problems for a stability-integrity based ecocentrism as well. We show how an ecocentric ethic can avoid these difficulties by emphasizing the (...) value of the wildness of natural systems and we defend wildness value from a rising tide of criticisms. (shrink)

The thesis that there can be vague objects is the thesis that there can be identity statements which are indeterminate in truth-value (i.e., neither true nor false) as a result of vagueness (as opposed, e.g., to reference-failure), "the singular terms of which do not have their references fixed by vague descriptive means". (if this is "not" what is meant by the thesis that there can be vague objects, it is not clear what "is" meant by it.) the possibility of vague (...) objects should not be taken, in itself, to imply the more radical thesis that the identity relation can be one of "degree". one can hold that the concept of degrees of identity is absurd (how can one thing be more or less identical to another?) "and" that indeterminacy in identity is possible; hence, any incoherence in the idea of degrees of identity does not thereby undermine the idea of indeterminate identity. (shrink)

Some ecologists, philosophers, and policy analysts believe that ecosystem health can be defined in a rigorous way and employed as a management goal in environmental policy. The idea of ecosystem health may have something to recommend it as part of a rhetorical strategy, but I am dubious about its utility as a technical term in environmental policy. I develop several objections to this latest version of scientism in environmental policy, and conclude that our environmental problems fundamentally involve problems in our (...) institutions of governance, our systems of value, and our ways of knowing. These are the problems that most need to be addressed. (shrink)

In this volume, the authors discuss what practical contributions ecology can and can't make in applied science and environmental problem solving. In the first section, they discuss conceptual problems that have often prevented the formulation and evaluation of powerful, precise, general theories, explain why island biogeography is still beset with controversy and examine the ways that science is value laden. In the second section, they describe how ecology can give us specific answers to practical environmental questions posed in individual case (...) studies, and argue for a new way to look at scientific error. A case study using the Florida panther is examined in the light of these findings. (shrink)

The concept and values of wilderness, along with the practice of wilderness preservation, have been under attack for the past several decades. In _Rethinking Wilderness_, Mark Woods responds to seven prominent anti-wilderness arguments. Woods offers a rethinking of the received concept of wilderness, developing a positive account of wilderness as a significant location for the other-than-human value-adding properties of naturalness, wildness, and freedom. Interdisciplinary in approach, the book combines environmental philosophy, environmental history, environmental social sciences, the science of ecology, and (...) the science of conservation biology.

An eloquent introduction to the ethical and philosophical values at stake in biological conservation, this book familiarizes readers with the general issues and possible solutions to the problems societies face in simultaneously conserving nature and promoting culture.

Reinventing Nature? is an interdisciplinary investigation of how perceptions and conceptions of nature affect both the individual experience and society's management of nature. Leading thinkers from a variety of fields - philosophy sociology, zoology, history, ethnobiology and others - address the conflict between the perception and reality of nature, each from a different perspective.

Contrary to frequent characterisations, exotic species should not be identified as damaging species, species introduced by humans, or species originating from some other geographical location. Exotics are best characterised ecologically as species that are foreign to an ecological assemblage in the sense that they have not significantly adapted with the biota constituting that assemblage or to the local abiotic conditions. Exotic species become natives when they have ecologically naturalised and when human influence over their presence in an assemblage (if any) (...) has washed away. Although the damaging nature and anthropogenic origin of many exotic species provide good reasons for a negative evaluation of such exotics, even naturally-dispersing, nondamaging exotics warrant opposition. Biological nativists' antagonism toward exotics need not be xenophobic and can be justified as a way of preserving the diversity of ecological assemblages from the homogenising forces of globalisation. Implications for Yellowstone National Park policy are explored. (shrink)

More than twenty years after its original publication, The Case for Animal Rights is an acknowledged classic of moral philosophy, and its author is recognized as the intellectual leader of the animal rights movement. In a new and fully considered preface, Regan responds to his critics and defends the book's revolutionary position.

Recent deconstructive developments in ecology (doubts about the existence of unified communities and ecosystems, the diversity-stability hypothesis, and a natural homeostasis or “balance of nature”; and an emphasis on “chaos,” “perturbation,” and directionless change in living nature) and the advent of sociobiology (selfish genes) may seem to undermine the scientific foundations of environmental ethics, especially the Leopold land ethic. A reassessment of the Leopold land ethic in light of these developments (and vice versa) indicates that the land ethic is still (...) a viable environmental ethic, if judiciously updated and revised.

Annotation. Informed by recent developments in literary criticism and social theory, this book addresses the presumption that nature exists independent of culture and, in particular, of language.
