As the world population is growing and government directives tell us to consume more fatty acids, the demand for fish is increasing. Due to declines in wild fish populations, we have come to rely more and more on aquaculture. Despite rapid expansion of aquaculture, this sector is still in a relatively early developmental stage. This means that this sector can still be steered in a favorable direction, which requires discussion about sustainability. If we want to avoid similar problems to the (...) ones we have experienced with livestock farming, we need to generate knowledge of the biology, profitability, environmental aspects, consumer awareness, and product appreciation of particular fish species. However, the discussion about a sustainable aquaculture also raises the question how we should treat fish. This moral question is regularly addressed as a problem of applied ethics with a focus on tailoring ethical principles to practical questions. In this article we do not deny the importance of the practical accounts, but we start from the fundamental question whether and why fish matter in our moral deliberations, i.e., from the discussion on moral status. We elaborate the distinction between moral considerability and moral significance in order to show both the importance and the limitations of the discussion about moral status for practical problems in aquaculture. We illustrate these points with a case-study about the farming of a specific fish species, the African catfish. (shrink)

Whereas theories on health generally argue in favor of one specific concept, we argue that, given the variety of health practices, we need different concepts of health. We thus approach health concepts as a Wittgensteinian family of thick concepts. By discussing five concepts of health offered by theory, we argue that all capture something that seems relevant when we talk and think about health. Classifying these concepts reveals their family resemblances: each of these concepts differs from the others in at (...) least one respect and resembles the others in several respects. Moreover, our classification shows that “health” always both describes a condition and evaluates that condition at the same time. Having both descriptive and evaluative dimensions, we can see health concepts as “thick concepts.” It is because of this evaluative dimension that it is important to reflect on the question of what understanding of health guides specific practices. We show that the distinctions revealed by our classification can serve as a conceptual toolbox for reflection on the assumptions and purposes of particular health practices. Finally, we illustrate how such reflection could work out by briefly exploring three specific health practices. (shrink)

Aquaculture is the fastest growing animal-production sector in the world. This leads to the question how we should guarantee fish welfare. Implementing welfare standards presupposes that we know how to weigh, define, and measure welfare. While at first glance these seem empirical questions, they cannot be answered without ethical reflection. Normative assumptions are made when weighing, defining, and measuring welfare. Moreover, the focus on welfare presupposes that welfare is a morally important concept. This in turn presupposes that we can define (...) the capacities of fish, which is an empirical undertaking that informs and is informed by ethical theories about the moral status of animals. In this article we want to illustrate the need for a constant interaction between empirical scientific research and ethics, in which both fields of research make their own contribution. This is not a novel claim. However, the case of fish sheds new light on this claim, because regarding fish there is still much empirical uncertainty and there is a plurality of moral views on all levels. Therefore, we do not only want to show the necessity of this interaction, but also the added value of a cooperation between ethicists and empirical scientists, such as biologists, physiologists, and ethologists. We demonstrate this by considering the different steps in the process of reflection about and implementation of fish welfare. (shrink)

Emerging infectious diseases such as Ebola, Hendra, SARS, West Nile, Hepatitis E and avian influenza have led to a renewed recognition of how diseases in human beings, wildlife and livestock are interlinked. The changing prevalence and spread of such infections are largely determined by human activities and changes in environment and climate—where the latter are often also caused by human activities. Since the beginning of the 21st century, these insights have been brought together under the heading of OneHealth—a concept that (...) calls for interdisciplinary collaboration between various sciences as well as professional practices to promote and protect the health of human and non-human animals and the natural environment. Just as insights from public health have led to a broadened focus for health policy and medical care, from treating individual patients to protecting and promoting population health, OneHealth calls for an even broader perspective, including a concern for the environment and animals, and for social-cultural factors that affect human, animal and environmental health. OneHealth not only covers collaborative work to understand and control zoonotic diseases, but also other ways in which interactions between animals, plants and humans may positively or negatively impact on each other’s health. Thus, studies in veterinary medicine and environmental sciences may lead to new insights in human medicine, and vice versa. Acknowledgment of the links between environmental, animal and social health is of course not a novel insight. Hippocrates already pointed to the importance of a clean environment as a requirement for good health; the early public health movements emphasized hygienic living conditions including good-quality housing, sewage systems and clean air and water; and the founders of modern medicine such as William Osler and Rudolf Virchow promoted ….

The leading question of this article is whether it is acceptable, from a moral point of view, to take wild animals that are ill out of their natural habitat and temporarily bring them under human control with the purpose of curing them. To this end the so-called 'seal debate' was examined. In the Netherlands, seals that are lost or ill are rescued and taken into shelters, where they are cured and afterwards reintroduced into their natural environment. Recently, this practice has (...) been criticised because it is thought to interfere with the wildness of the animals and population. In this research, the moral assumptions behind the arguments of both the proponents and opponents of sheltering have been analysed within a morally pluralistic framework. It is concluded that sheltering on too large a scale would be contrary to the efforts of the last few decades to maintain an independent or wild seal population, which means that a certain amount of caution is called for. However, in the current situation there is no decisive reason to completely prohibit shelters either. Good arguments can even be given in favour of sheltering. It also becomes clear that the acceptability of sheltering wild animals depends on the specific circumstances in which an animal is encountered. (shrink)

Pedigree dog breeding has been the subject of public debate due to health problems caused by breeding for extreme looks and the narrow genepool of many breeds. Our research aims to provide insights in order to further the animal-ethical, political and society-wide discussion regarding the future of pedigree dog breeding in the Netherlands. Guided by the question ‘How far are we allowed to interfere in the genetic make-up of dogs, through breeding and genetic modification?’, we carried out a multi-method case-driven (...) research, reviewing literature as well as identifying the perceptions of pedigree dog breeding of a variety of parties in the Netherlands. We examined what moral arguments and concepts different stakeholders, including breeders, veterinarians and animal protection societies, put forward when considering this question. While welfare arguments were often used as a final justification, we also frequently encountered arguments beyond welfare in practice, in particular the arguments that certain adaptations were unnatural, that they instrumentalised animals, or that they amounted to playing God. We argue that the way these arguments are employed points to a virtue ethical approach, foregrounding the virtue of temperance, as a balance between extreme positions was sought by our respondents in a variety of ways. Moreover, we argue against a rejection of unnaturalness arguments based on the naturalistic fallacy, as philosophers tend to do. We point out that unnaturalness arguments are related to people’s worldviews, including views on the proper human–animal relationship. We argue that such arguments, which we label ‘life-ethical’, should be the subject of more public discussion and should not be relegated to the private sphere. (shrink)

Climate change could be described as an unstructured policy problem, in which we encounter disagreement on facts and values, problem definition, policy aims, procedures and instruments. For the solution of this type of problem public deliberation is often proposed. According to theories of deliberative democracy all those potentially affected by a decision should have the opportunity to participate in the drafting of that decision. However, in the context of climate change many of the potentially affected cannot speak for themselves, because (...) they do not yet exist. Could future generations nevertheless be represented in public deliberations? And if so, who could legitimately represent them? Moreover, how could such representation get shape institutionally within a deliberative democracy? I will examine some obstacles––in particular the non-identity and the pluralism problems––that have to be overcome before future generations can be represented and question how deliberative democracy could deal with these..
