In this chapter I consider two different perspectives on what it means to acknowledge and embrace anthropogenic ecological change with respect to ecosystem management and species conservation. On one view, embracing anthropogenic change involves taking greater responsibility for and control of the ecological future. We ought to use our best science and technology to thoughtfully and intentionally manage, and where necessary design and modify, ecological systems and species. On another view, embracing ecological change involves reducing human influences and allowing systems and species space and opportunities to transition and reconfigure without intentionally designing them in accordance with how we think they need or ought to be. Anthropogenic change does not itself imply that there is a responsibility to take an interventionist and control-oriented approach to ecosystem management and species conservation. Whether and when people ought to do so will vary by case and context, not only in accordance with the relevant empirical information, but also in accordance with the operative values as stake.

Discourse around assisted colonization focuses on the ecological risks, costs, and uncertainties associated with the practice, as well as on its technical feasibility and alternative approaches to it. Nevertheless, the ethical underpinnings of the case for assisted colonization are claims about the value of species. A complete discussion of assisted colonization needs to include assessment of these claims. For each type of value that species are thought to possess it is necessary to determine whether it is plausible that species possess the type of value and, if so, to what extent their possessing it justifies assisted colonization. I conducted such an assessment for each of the predominant types of value ascribed to species: ecological, instrumental (including option value), existence, and intrinsic value (including interest‐based, objective, and valuer‐dependent intrinsic value). The vast majority of species, including several that have been proposed as candidates for assisted colonization, have much less value than is often presumed. Moreover, with respect to some types of value, assisted colonization would not fully preserve the value of the target species even if it were to keep the target species in existence. Therefore, the case for assisted colonization is significantly weaker and more qualified than its advocates often suppose. There may be exceptional species for which assisted colonization is well justified—and for this reason, case‐by‐case assessment is necessary—but in general the burden of justification generated by the ecological risks associated with assisted colonization is not met by the value potentially preserved by assisted colonization. This suggests that assisted colonization ought to have, at most, a very minor role in the portfolio of ecosystem management practices, even as it pertains to species conservation under conditions of rapid climate change

Environmental ethics (see Environmental Ethics) is the study of the ethical relationships between human beings and the natural environment, including the nonhuman individuals that populate and constitute it. It involves developing a proper understanding of the human–nature relationship, identifying the goods and values that are part of or emerge from that relationship, determining the norms (rules/principles) that those goods and values justify, and applying those norms to generate guidance on environmental issues and interactions. Environmental virtue ethics is that part of environmental ethics that concerns character (see Virtue Ethics). The core questions of environmental virtue ethics are these

The central claims defended in this article are the following: (a) The social and ethical challenges of nanotechnology can be fully identified only if both the characteristic features of nanotechnologies and the social contexts into which they are emerging are considered. (b) When this is done, a host of significant social context issues, or issues that arise as a result of problematic features of the social contexts into which nanotechnology is emerging, become salient. (c) These issues can only be addressed by remedying the problematic features of the social contexts, which cannot be accomplished by technology design or risk management alone. (d) The U.S. National Nanotechnology Initiative's conceptualization and operationalization of responsible development does not adequately recognize the significance of social context issues to responsible development. (e) Therefore, the National Nanotechnology Initiative is not yet comprehensive and needs to be expanded with respect to identifying and addressing social context issues.

This dissertation is a systematic study of Spinoza's ethical system as a virtue ethic. Spinoza's ethical theory has been under-appreciated in this regard and has therefore been virtually ignored by contemporary virtue ethicists who have looked almost exclusively to the ancients as a source of insight regarding the virtues. With my dissertation I aim both to contribute to Spinoza scholarship and to provide an historical resource to contemporary ethicists working in the area of virtue. ;The dissertation can be divided into two parts. The first part, Chapters One thru Four, deals mostly with Spinoza's metaethic and the rudiments of Spinoza's normative ethic. These chapters include a discussion of spinozistic value, the dictates of reason and Spinoza's ethical intellectualism. These chapters lay the foundation for the more explicit discussion of Spinoza's virtue ethic that takes place in Chapters Five thru Seven. In these later chapters I focus on the following questions: To what extent is Spinoza's ethical theory properly a virtue ethic? What is the structure of his virtue ethic? Does it resemble any of the virtue ethics of the ancients? In what sense is, as Spinoza insists, virtue its own reward? Is Spinoza's intellectualist virtue ethic internally cogent? I argue, inter alia, that Spinoza's ethical theory is properly a virtue ethic, that it does differ in interesting ways---particularly methodologically---from most ancient virtue ethics and that Spinoza recognizes three distinct benefits for those who live virtuously. ;In the final chapter I treat what I take to be the central issue regarding the cogency of Spinoza's intellectualist virtue ethic. Does the intellectual state that Spinoza identifies with virtue and advocates cultivating deliver on what it promises in terms of the rewards of virtue? The answer, I argue, is that it does not. However, I further argue that Spinoza's ethical theory is not thereby devastated. There is room for a sympathetic spinozean to remedy this defect. The defect merely reveals that there is significant ethical theorizing, beyond what Spinoza himself provides, that needs to be done
