Relocation is an increasingly prominent conservation tool for a variety of wildlife, but the technique also is controversial, even among conservation practitioners. An organized framework for addressing the moral dilemmas often accompanying conservation actions such as relocation has been lacking. Ecological ethics may provide such a framework and appears to be an important step forward in aiding ecological researchers and biodiversity managers to make difficult moral choices. A specific application of this framework can make the reasoning process more transparent and (...) give more emphasis to the strong sentiments about non-human organisms held by many potential users. Providing an example of the application of the framework may also increase the appeal of the reasoning process to ecological researchers and biodiversity managers. Relocation as a conservation action can be accompanied by a variety of moral dilemmas that reflect the interconnection of values, ethical positions, and conservation decisions. A model that is designed to address moral dilemmas arising from relocation of humans provides/demonstrates/illustrates a possible way to apply the ecological ethics framework and to involve practicing conservationists in the overall decision-making process.

A rational process for assessment of environmental policy options should be based on an appreciation of how humans value nature. Increased understanding of values will also contribute to the development of appropriate ways for us to relate to and manage natural areas. Over the past two decades, environmental philosophers have examined the notion that there is an intrinsic value in nature. Economists have attempted to define and measure the market and nonmarket economic values associated with decisions concerning natural areas. Psychologists (...) have tried to assess the extent to which people believe in an intrinsic value in nature, and have also begun to work with economists to improve nonmarket valuation techniques. I briefly review the contributions made to our understanding of natural area value by environmental philosophy, psychology and economics, and develop a model that integrates insights from these disciplines. Components in the model include cognitions, held values, assigned values and various modes of value expression. I make recommendations for future validation, development and use of the model.

Environmental ethics is generally searching for the intrinsic value in natural beings. However, there are very few holistic models trying to reflect the various dimensions of the experience-to-be a natural being. We are searching for that intrinsic value, in order to determine which species are holders of rights. In this article, I suggest a set of moral and rational principles to be used for identifying the intrinsic value of a given species and for comparing it to that of other species.

The COVID-19 pandemic once again confirmed that zoonotic diseases are a serious threat to humanity. These infectious diseases, transmitted from animals to humans, have the power to cause a global health crisis. Over time the risk on these outbreaks has increased. Some of the main drivers are global population growth, urbanization, worldwide transport, increased demand for animal protein, unsustainable agriculture, and climate change. This development has fueled a renewed interest in the relation between human, animal and environmental health. This was (...) framed in the concept of One Health: the integrative effort of multiple disciplines working locally, nationally, and globally to attain optimal health for people, animals, and the environment. At present, One Health is the worldwide standard to combat zoonotic diseases. In an ideal world such a strategy should lead to a better health for humans, animals and our environment. However, in practice it is not self-evident that a One Health approach in zoonotic disease control is actually in the interest of animals or the environment. From a holistic One Health perspective it can be difficult to accept the culling of healthy animals to protect public health. The same goes for long term confinement of free-range poultry, whose housing systems are often not suitable for this purpose, to prevent avian influenza outbreaks. Or antimicrobial reduction policies that lead to higher disease incidence and mortality in animals. These ethical considerations formed the start of this thesis. The aim of my research is to clarify the ethical assumptions of a One Health approach in zoonotic disease control, to explore how these can be coherently understood and justified and to indicate what this implies for policymaking. The outcome of my research contributes to the development of an ethic of One Health and will hopefully lead to a more socially acceptable zoonotic disease control. This project is related to the interdisciplinary Wageningen UR strategic research theme ‘Global One Health’. From my conceptual analysis, it follows that there is no universal interpretation of the One Health concept nor of a One Health approach in zoonotic disease control. Nevertheless, One Health has produced several successes in zoonotic disease control, surveillance and research. Due to its ambiguity, the One Health concept functions as a boundary object: by leaving room for interpretation to fit different purposes it facilitates cooperation. In many cases this results in the promotion of health of humans, animals and the environment. However, there are also situations in which this mutual benefit of a One Health approach is not that evident. For instance, when healthy animals are culled to protect public health. To address these moral dilemmas, it is important to develop an ethical framework. Such an ethic of One Health starts with acknowledging the moral status of animals and the indirect moral obligations we have towards ecosystems. Furthermore, it is necessary that we find an appropriate definition of health, which encompasses all three components of One Health. In chapter 3, I present the results of an empirical study on normative presuppositions of health professionals involved in zoonotic disease control policies in the Netherlands. This study reveals that in theory these professionals adhere to a holistic view of the One Health concept. However, in practice an anthropocentric approach was dominant. The study identified public health as a trumping moral value, which reveals an inherent field of tension with the core of One Health thinking. Furthermore, a lack of ethical expertise in control systems for zoonotic diseases can lead to misconception of ethical principles, like the precautionary principle. In chapter 4, I discuss that within a One Health strategy, that requires us to balance public health benefits against the health interests of animals and the environment, unrestricted use of the precautionary principle can lead to moral dilemmas. It must at least be clear that there is a harm and some scientific evidence for a cause and effect relation. Furthermore, precautionary measures should be effective, consistent, proportional and not counterproductive. An assessment of their effect should be integrated in the standard decision-models of public health authorities. Moreover, to ensure societal support these considerations should be transparent and open for dialogue. I present two possible conceptions of the precautionary principle. First, it is noticeable that because of the unpredictable nature of zoonotic diseases, public health authorities focus on the idea of ‘precaution as preparedness’. This reactive response leads to difficult trade-offs between human and animal health. I therefore argue that this policy should always be accompanied by a second policy: ‘precaution as prevention’. Addressing the underlying drivers of zoonotic diseases is a necessary condition to justify disease control measures that harm animals and ecosystems on the basis of the precautionary principle. In chapter 5, I elaborate the responsibilities of veterinarians within the One Health framework. Veterinarians are professionally responsible for the health and welfare of the animals under their care. Moreover, society expects veterinarians to safeguard food safety and public health. These societal expectations are sometimes overdemanding. A holistic perspective on One Health offers veterinarians a way out of the dichotomy between public and animal health, that is at the basis of many moral dilemmas in zoonotic disease control. This is explained with the ‘encapsulated health’ argument: the best way to safeguard human health is to promote the health of animals and the environment. In chapter 6, I conclude that before we decide to implement certain disease control measures, an ethic of One Health requires that we choose those interventions that have the least impact on the health of animals and ecosystems, while still effective enough to stop the disease. My research indicates that the contemporary conception of One Health is necessary but insufficient to address moral dilemmas related to emerging zoonotic diseases. A holistic interpretation of the One Health concept confronts us with underlying value conflicts but will ultimately promote human health more than the current anthropocentric conception. (shrink)

The aim of this investigation is to answer the question of why it is prima facie morally wrong to cause or contribute to the extinction of species. The first potential answer investigated in the book is that other species are instrumentally valuable for human beings. The results of this part of the investigation are that many species are instrumentally valuable for human beings but that not all species are equally valuable in all cases. The instrumental values of different species also (...) have to compete with other human values. Sometimes these other values probably outweigh the value of the continued existence of the species. In general the degree of uncertainty is very high and the precautionaty principle is recommended to deal with these uncertainties. We also found that we have a duty to consider the interests of future generations of human beings and that these duties, in general, speak in favour of preservation. Anthropocentric instrumentalism therefore provides us with rather strong reasons to consider many cases of human caused extinction as prima facie morally wrong. Even so, anthropocentric instrumentalism does not fully account for the moral intuition we set out to investigate. The next potential answer that is investigated in the book is that species have a moral standing in their own right. The result of this part of the investigation is that this idea is highly unlikely, in particular because species cannot have any interests to consider. Anotgher potential answer is that species have intrinsic value in some other meaning that does not imply moral standing. We concluded that it is possible to be subjectively valued as an end and that many species have properties that make them highly suitable for being valued as ends by human beings. Finally, we found that our contributions to the extinction of species in most cases frustrate the interests of many non-human sentient beings. This is true if the species in question is made up of sentient individuals, and it is also true when the species in question is made up of non-sentient individuals that have instrumental value for sentient individuals of other species. There are exceptions to this rule, but all in all it seems that the inclusion of non-human sentient individuals together with us humans as moral objects, in most cases, tip the scale drastically in favour of preservation. The main result of the investigation is that there is not one but several explanations to why it is prima facie morally wrong to contribute to the extinction of species – and all of them are about duties to respect the interests of individual sentient animals, including human beings.
