Collectively, those species of wildlife are known to feed on eggs, adults, and nestlings of ground nesting bird species, including threatened and endangered (T&E) bird species, and will be referred to collectively as nest predators2 throughout the EA. Normally, individual wildlife damage management actions conducted by the WS program could be categorically excluded from further analysis under the National Environmental Policy Act (NEPA), in accordance with APHIS implementing regulations for the NEPA (7 CFR 372.5(c), 60 FR 6000-6003). The purpose of this Environmental Assessment (EA) is to evaluate activities conducted by WS to manage predation and the threat of predation on federal and state-listed T&E species. This EA will also evaluate the issuance of depredation permits by the Migratory Bird Division of the United States Fish and Wildlife Service (USFWS) for the take of protected bird species pursuant to the Migratory Bird Treaty Act (MBTA). In addition, this EA will facilitate planning between WS, the USFWS, and the Maine Department of Inland Fisheries and Wildlife (MDIFW) to initiate funding mechanisms under grant programs administered by the Wildlife and Sport Fish Program for the conservation of T&E species. Other federal funding mechanisms through the USFWS, including Endangered Species Act (ESA) recovery implementation funds or refuge project funds may also be evaluated and utilized to reduce the risk of predation. The development of this EA by WS and the cooperating agencies will assist in determining if the proposed management of predation on nesting bird populations along the coastal islands and coastal areas of the State could have a significant impact on the environment for both humans and other organisms. The EA will also assist with identifying and addressing issues associated with managing predation risks. In addition, the EA will analyze alternative approaches to address those issues. This EA will also be a planning document

  • The Core Argument for Veganism
    Philosophia (2015) 43:271–290 DOI 10.1007/s11406-015-9595-5 The Core Argument for Veganism Stijn Bruers1 Received: 11 November 2014 /Revised: 16 March 2015 /Accepted: 23 March 2015 / Published online: 4 April 2015 # Springer Science+Business Media Dordrecht 2015 Abstract This article presents an argument for veganism, using a formal-axiomatic approach: a list of twenty axioms (basic definitions, normative assumptions and empirical facts) are explicitly stated. These axioms are all necessary conditions to derive the conclusion that veganism is a moral duty. The presented argument is a minimalist or core argument for veganism, because it is as parsimonious as possible, using the weakest conditions, the narrowest definitions, the most reliable empirical facts and the minimal assumptions necessary to reach the conclusion. If someone does not accept the conclu- sion, logical consistency requires that s/he should be able to point at axiom(s) on which s/ he disagrees. The argument exposes hidden assumptions and provides a framework for an overview of the philosophical literature on animal rights and vegetarianism / veganism. Keywords Veganism . Speciesism . Animal ethics . Sentience Is veganism a moral duty? This article is an attempt to present a most logical argument for veganism,1 using a formal-axiomatic approach: all axioms (premises such as basic definitions, normative assumptions and empirical facts), as well as the logical steps from those axioms to the conclusions, will be stated as explicitly as possible. This axiomatic approach has three advantages. First, it allows us to directly and efficiently study the question: if people want to continue eating animal products, which of the assumptions do they reject? Everyone who wants to justify the consumption of animal products should be able to indicate at least one of the axioms that s/he rejects.

He allowed me to explore many new paths in ethics and philosophy and he took time to guide me through the research. His assistance and advice were precious. Second, I owe gratitude to Prof. Dr. Tom Claes and Tim De Smet for comments and Dianne Scatrine and Scott Bell for proofreading. Thanks to Gitte for helping me with the lay-out and cover. Thanks to the University of Ghent for giving opportunities, knowledge and assistance. From all philosophers I know, perhaps Floris van den Berg has ethical ideas closest to mine. I enjoyed our collaboration and meetings with him. Also the many discussions with animal rights activists of Bite Back, with the participants at the International Animal Rights Conferences and Gatherings and with the many meat eaters I encountered during the years allowed me to refine my theories. Furthermore, I am grateful to anonymous reviewers for some useful comments on my research papers.

    FREE ANIMAL LIBERATION: THE DEFINITIVE CLASSIC OF THE ANIMAL MOVEMENT PDF Decamp Professor of Bioethics Peter Singer | 311 pages | 01 Mar 2009 | HarperCollins Publishers Inc | 9780061711305 | English | New York, NY, United States Animal Liberation: The Definitive Classic of the Animal Movement - Peter Singer - Google книги Arguing that all beings capable of suffering deserve equal consideration, Singer contends that the only justifiable treatment of animals is that which maximizes good and minimizes suffering. A moral wake-up call from one of the most influential and controversial ethicists of our time, Animal Liberation tackles an emotionally charged social issue with a compelling rational argument in a rousing and riveting read. A pioneering work which places animal treatment by people withing the ambit of human ethical behaviour. Whoever else deals with this subject, Peter Singer will always be the first philosopher to have confronted, analysed and resolved many of the key arguments. In the past, I can only think of St Francis of Assisi as a someone of significance who considered how non-human animals should be treated. Singer takes it to the next level which demands we change how we conduct ourselves. In the first half of the book, Singer opens our eyes in regards to how we treat the staggering majority of animals today. In the the second half, he shows us the way to a more ethical life. All with overwhelming evidence, using reason, logic, and unbiased scientific reference. One of the more important books in my life, insofar as it inspired me to switch from eating meat to being a pescatarian.

  • Should the Lion Eat Straw Like the Ox? Animal Ethics and the Predation Problem
    J Agric Environ Ethics DOI 10.1007/s10806-016-9637-4 ARTICLES Should the Lion Eat Straw Like the Ox? Animal Ethics and the Predation Problem Jozef Keulartz1,2 Accepted: 25 August 2016 Ó The Author(s) 2016. This article is published with open access at Springerlink.com Abstract Stephen Clark’s article The Rights of Wild Things from 1979 was the starting point for the consideration in the animal ethics literature of the so-called ‘predation problem’. Clark examines the response of David George Ritchie to Henry Stephens Salt, the first writer who has argued explicitly in favor of animal rights. Ritchie attempts to demonstrate—via reductio ad absurdum—that animals cannot have rights, because granting them rights would oblige us to protect prey animals against predators that wrongly violate their rights. This article navigates the reader through the debate sparked off by Clarke’s article, with as final destination what I consider to be the best way to deal with the predation problem. I will successively discuss arguments against the predation reductio from Singer’s utilitarian approach, Regan’s deontological approach, Nussbaum’s capability approach, and Donadson and Kymlicka’s political theory of animal rights. Keywords Predation problem Á Utilitarianism Á Rights theories Á Capability approach Á Political theory of animal rights Introduction Stephen Clark’s article The Rights of Wild Things from 1979 was the starting point for the consideration in the animal ethics literature of the so-called ‘predation problem’ (Dorado 2015, 234).

Inthe South African social-policy researcher was collecting data for her PhD on the outcomes of government Academic Identities in Higher Education The Changing European Landscape 1st edition grants. But seeing the embarrassment in home after home as people opened their often- empty pantries, Zembe-Mkabile felt something was amiss. At the time, she did not act on her unease. Only years later, as an established scientist, did Zembe-Mkabile begin to understand the complexity of her apprehension. Community-based research often puts young scientists in a position of power over research participants, a role that can be daunting and unfamiliar. But for Zembe-Mkabile, the feelings went deeper. The vestiges of that power imbalance were still there in her kitchen encounters. Zembe-Mkabile grew up around poverty, but as a scientist trained at the University of Oxford, UK, she was the product of a system shaped by and for white Europeans. The tension between these two roles — the insider and the outsider — is central to her identity as a researcher, and has shaped her thinking about how research can, and should, be done.

  • Management Tools for Reconciling Bird Hunting and Biodiversity
    RECONCILING GAMEBIRD HUNTING AND BIODIVERSITY (REGHAB) CONTRACT No: EVK2-CT-2000-200004 PROJECT COORDINATOR: Javier Viñuela Instituto de Investigación en Recursos Cinegéticos (IREC), Ronda de Toledo s/n, 13005-Ciudad Real, Spain PROJECT WEBPAGE: www.uclm.es/irec/Reghab/inicio.html (Report on Workpackage 4 – Deliverables no 14-16). Management tools for reconciling bird hunting and biodiversity. Robert Kenward July 2002 Natural Environment Research Centre - Centre for Ecology and Hydrology, Winfrith Technology Centre, Dorchester DT2 8ZD, United Kingdom 1- INTRODUCTION Previous work-packages have reviewed socio-economic aspects of hunting (WP 1), potential benefits for conservation of biodiversity (WP 2) and problems for biodiversity (WP 3). In recent years, much social pressure has developed against hunting. The historical practice of banning hunting save for the aristocracy often changed in young European democracies to a free-for-all in which game species (especially deer) and predators were extirpated over large areas (WP 1). In Britain and other European countries, the aristocracy had also protected raptors for use in falconry (Cooper 1979), yet later predation on game and livestock motivated extirpation of raptors, often supported by bounty payments (Newton 1979). Reaction to these "tragedies of the commons" (Hardin 1968) and to the original privileged status of hunting, accompanied by anthropomorphic and romantic views of "nature" in urbanised societies (Wilson 1984, Taylor 1986), have resulted in antipathetic attitudes to hunting. That early tradition of conservation by a knowledgeable and powerful minority has gradually re-established within democracies, but in this case (appropriately) as a plurality. On the one hand are the hunters, often associated with land-owning or other aspects of social status, who have promoted study and conservation of game, typically with mostly unmeasured benefits for biodiversity (WP 2).
