Abstract

One health suggests that human and animal health are comparable, but in practice, the concept aligns with the principles of public health ethics. One health ethics, as such, appears to eschew connotations of equality for the natural world. A theory of agency revises that anthropocentric assumption. This article begins with a critique of environmental dualism: the idea that human culture and nature are separate social realms, thus justifying public health as a (unifying) purpose. In response, this article argues that, first, a neuroethics of one health might equally regard humans and (some) animals, which have comparable mental states, as rational agents. Second, rational agency should ground our moral connections to nature in terms of the egalitarian interests we have (as coinhabitants) in the health of the planet. While this article makes a moderate case for interspecific rights (as the first argument asserts), neuroscience is unlikely for now to change how most public institutions regard nonhuman animals in practice. However, the second argument asserts that rational agency is also grounds for philosophical environmentalism. One health ethics, therefore, is a theory of equality and connects culture to nature, and, as such, is a separate, but coextensive approach to that of public health.

Introduction

The contemporary one health movement has been defined as an instrumental approach to augmenting public health by enhancing health at the human–animal–environment interface.Footnote 1 Variations of this anthropocentric view are now common in national and global responses claiming to use the one health approach.Footnote 2 On the one hand, if one health is merely descriptive of disciplinarity in contexts where humans interact with their environments, then further normative discussion is perhaps redundant.Footnote 3 In this respect, the collaborative approach to one health has been cautiously welcomed, but critically relies on the assumption that “optimal health” is exclusively a matter for human beings, despite other plausible interests at the environmental nexus.Footnote 4 On the other hand, one health ethics also alludes to interconnections or interdependencies between species, and shared interests in the places they live.Footnote 5

In this article, one health ethics is framed as a philosophical critique of environmental dualism. Dualism is the claim that “human culture” and “nature” are separate legal, moral, and social realms. In this respect, I presume that ethical biases toward cultural (or social) determinants of health influence one health as it is currently practiced, thus defining its scope as an environmental philosophy. Although there is perhaps some agreement that the intrinsic value of animals and the environment must be considered in one health, there is uncertainty about their value as compared to the value of humanity. Such issues are, therefore, (unconsciously or conveniently) positioned within public health ethics. So, while a pragmatic case for one health infers that human culture remains a disassociated phenomenon from natureFootnote 6 (and speaks to enhancing public health), a critical view suggests that the environmental challenges we now face are a consequence of anthropocentric models that are indifferent to our moral presence in the natural world.Footnote 7

In the first section, I sketch one sense of environmental dualism as rooted in questions about “having moral status.” In this respect, although different species have distinct capabilities and socialities, there are also ways to conceptualize similar states of health, and to conceive of their shared interest through habitat loss, globalization, land use, and climate change.Footnote 8 These connections raise neuroethical implications about agency: specifically, rational nature objectively conceives of conditions for moral rights claims, and so defines our duties to modify our behavior such as to try to ameliorate unjust environmental consequences. Thus, in the second section, I argue that if there are plausible analogous mental states between species, then there are also comparable interspecific interests in the conditions for health, so that in theory we ought to equally regard mutual benefits for humans and such animals.Footnote 9 However, a neuroscientific basis for one health is likely to be constrained by impracticability, which will become evident if it in theory disrupts practice rooted in the anthropocentric outcomes of public health. So, in the third section, it is suggested that agency (as a neuroscientific phenomenon) also becomes a “fulcrum against which the world might be moved”Footnote 10: reasonable agents, as such, have a moral point of view orientated toward “nature.” Nature, therefore, is necessarily a vital place for both persons and for other coinhabitants of Planet Earth. This article suggests that agency underlies one health ethics as a rational approach to our relationship to nature.

Culture and Nature

The disconnect, separateness, and otherness between “culture” and “nature” is a long-standing debate (across multiple disciplines).Footnote 11 Such duality has often underpinned societies’ treatment of animals and the environment, through dichotomous boundaries of “soul” and “soulless,” “cognition” and “automata,” “mind” and “sentience,” and “rational” and “animalistic.” For my purposes, culture may be defined as inter alia creation, storage, and implementation of socially learned information, outcomes of high levels of cause-and-effect reasoning, and a capacity to undertake sophisticated cooperative action.Footnote 12 That begs the question: What is it about human culture that makes it sufficiently morally different from the animalistic lives around us? And if a difference exists, how should we regard nonhuman nature as separate from our own human kind?

Dualists might agree that human culture is a post-evolution progression when measured in terms of magnitude and hyperdevelopment.Footnote 13 Our ultrasociality is evident in our complex institutions, which require complex laws and moralities to govern.Footnote 14 These accomplishments arise only in the brains of human beings; neurology, therefore, must give rise to the perfection of humanity and the imperfection (or brute physical force) of nature.Footnote 15 This uniquely human characteristic suggests that cultural artifices, such as public health, are only possible because of presence of humanity’s self-creation in the transformation of our environments. In contrast, nature, under this narrative, appears to be spontaneous rather than rational, unaffected by the presence of mind, and wild and uncultivated (I would also note that traditionally “nature” is illustrative of an impossibly contested notion, and there are few concepts as slippery). The point of this particular narrative, however, is that nature—the natural world and nonhuman nature—is instrumental to human well-being; it is meant to be inhabited, used, and manipulated.Footnote 16

Environmental dualism is a socio-legal phenomenon, illustrated, for example, by the ongoing debate about purposively recognizing animal rights by extending “legal personhood” beyond human beings.Footnote 17 In this respect, it might be said that a legal system conceived by and for human interests, is reasonably unrelatable to animals’ interests or the telos of the environment.Footnote 18 Similarly, the science of public health is increasingly understood in terms of the social determinants of health; as such, public health creates a specific perspective about tackling health inequalities, as they follow an experiential gradient with respect to the conditions under which persons are born, grow, live, work, and age.Footnote 19 Health, in this sense, is a cultural phenomenon that includes environmental barriers to persons experiencing control in terms of successful agency. Dualists think that animals do not have these experiences (and therefore have no need for public health, social services, or economic and legal insitutions), and, as such, human interests are “alienated” from nature.Footnote 20 Although this infers speciesism, the culture–nature gap may be bridged through modified environmentally friendly institutions, where nature is a passive beneficiary of such ethical reconnection.Footnote 21

Public health may be defined as a superstructure built on human rights, in terms of its focus on individual responsibility and collectivism and collective rights generated by the public good.Footnote 22 The principle of the public interest, therefore, describes the processes that secure such goods beneficial to communities, humanity, and the human species.Footnote 23 Nature is therefore largely an ecosystem service; and natural elements, such as companion animals, working animals, and natural esthetics (the awesome beauty of nature), are defined through a lens of human well-being.Footnote 24 In these respects, a notion of cultural environmentalism Footnote 25 is the primary anchor for relevant aspects of public health ethics, which corresponds to a focus on controlling our environments, mitigating degradation of spaces, and avoiding resource depletion that eventually affects all of humanity. Ethical inferences in this regard are made from anthropocentric doctrines about population health and preventative medicine.Footnote 26 Environmental solutions are found in the conditions for economic growth (i.e., greening economies and sustainable ecoservices) and sociality (e.g., understanding social connections to nature).Footnote 27 As a result, a broad range of environmental perspectives emerge from social justice lenses,Footnote 28 so that environmentalism carries assumptions about “who benefits” (e.g., from a green economy) and “who bears the burdens” (e.g., of pollution).Footnote 29

Dualism, therefore, defines the “boundaries of the moral community [that] are coextensive with the boundaries of the perceived social community. And sentient beings, so far as [Charles] Darwin knew, did not form a community with man [sic].”Footnote 30 Except animals are part of our contemporary communities—as socially constructed companions, workers, livestock, and pests.Footnote 31 Framing one health as an anthropocentric narrative creates inconsistencies; for example, humans as persons may be “vaccinated” to a disease (and we debate the autonomy of choice and the public interest), but in the same instance, animals as nonpersons are “culled” to protect public health or economies. These potentially superfluous conditions may be described in normal language as discriminatory toward some species or (nonhuman) individuals.Footnote 32 Moreover, culture—human activity—is at the root of excessive and exploitative demands on ecoservices; it justifies lowering animal welfare for economic reasons, promulgating psychological and physiological cruelty; and disregards the bonds between humans and nonhuman companions.Footnote 33 Culture creates animal markets and trade, factory farms, and the entertainment industry, which are potentially causal to our present environmental crises.

Philosophical environmentalism, therefore, may be used to critique the adaption of public health frameworks that normally eschew substantive environmental theories; principally, it is a method to cast doubt on presumptive dualism and the assumption that there can be no consilience between theories of human health and animal health. In this respect, we can define the environmental determinants of health, such as exposure to pollution and chemicals (e.g., air, water, soil, and products), physical exposures (e.g., noise and traffic), the built environment, and other anthropogenic changes (e.g., climate change), as affecting “cultural” and “natural” beings alike. In this regard, a philosophy of one health may relate to species—connected as if having “one” interest, in the sense of inhabiting the same places and experiencing similar conditions of “health.” Therefore, if dualism presupposes that in this shared planetary space there are ostensibly only moral claims to promote human interests, then one health might diverge greatly from the anthropocentric vision of public health.Footnote 34

The Neuroethics of One Health: An Argument for Interspecific Rights

One area where dualism persists is in neuroethics. For example, a dualist might argue that cognitive mental states (of the kind “I” know exist in “my” mind) are not found in “unconscious” nature; culture, in this respect, requires a noosphere or “thinking arena,” and that creates our unique place outside of the natural world.Footnote 35 The dualist must contend with explaining such mental states as something that some have, and others do not, in contexts that have profound ethical consequences.Footnote 36 The study of neuroethics, however, is conspicuously absent from the one health movement.Footnote 37

Moral status may be defined as categorical, sentient, or rational. A categorical approach (in the sense that “human moral status” is a prescriptive norm) is often used to distinguish the moral worth of human beings from (whatever other value is common to) all other species.Footnote 38 Culture, therefore, is “what people are” as “constructed by people,”Footnote 39 so that an ethical society may accord absolute value to its own kind (i.e., on the basis that we cannot deny any human being full personhood), and thereby justify institutions that unconditionally protect and promote these rights.Footnote 40 Because environmental dualism materializes “at the human–animal interface,” public health suggests that individual agency is (or definitive mental states are) less relevant to achieve categorical targets for health (i.e., human communities): it is meant to be inclusive of all or most human beings.Footnote 41 Personhood, in this regard (in normative democracies), is often specified by the outcomes of deliberative ethics; and society’s “laws” emerge as positivist toward “legal persons” who are defined by convention, tradition, or sentiment. Thus, by evoking the partial idea that nature is a “social construct based on human expectations and knowledge,”Footnote 42 the discursive grounding of ethical frameworks helps implement governance of environmentally friendly policies.Footnote 43 In terms of nature’s relative value to humanity, we are not meant to have naturally egalitarian obligations toward it.

Neuroethics might usefully reframe the one health debate by challenging the assumptions of environmental dualism, however: “deepening understanding of the ways that nervous systems and brains are involved in (or evoke) those characteristics that are valued in individuals, groups, and a species should compel and sustain the ways that the organisms that possess such characteristics are regarded and treated.”Footnote 44 Neuroscience, in this respect, justifies using an interspecific concept such as agency—a concept “less speciesist and less blind to the moral importance of abstract or dispersed aspects of nature such as ecosystems, habitats, species or biodiversity.”Footnote 45

Agency refers to the morally relevant attributes of an entity, that may be, but are not necessarily generalizable, to a group or species.Footnote 46 Unlike categorical “persons,” agents are defined by objective status attributes. So although the agency is a biological-related-to-psychological phenomenon (thus is indicative of sentience), its uniquely practical logocentric meaning (that it is rationality-centered) distinguishes “persons” from “things.”Footnote 47 Rational nature signifies an ability to employ means in pursuit of ends freely chosen.Footnote 48 So, assuming agents have the capacity for practical rationality, their actions are ethical or reasonable when they recognize all agents as equal in dignity and rightsFootnote 49: agents morally take “due account of the interests of other persons, respecting their right as well as one’s own and maintaining a certain equitableness or mutuality of consideration between oneself and others.”Footnote 50 As such, the “final worth” of the individual is the necessary reason for addressing them as moral beings, in ways that are egalitarian toward their natural rather than just human rights.Footnote 51 We must therefore use impartial description of equivalence with respect to generic goods, and in this respect, although all agents have equal rights, they have different needs with respect to capabilities (and access to goods); such discernment is the subject of theories of justice.Footnote 52 This dialectic approach is dualistic, but only in the nonhumanistic way just specified; and, now makes justice central to the one health narrative.Footnote 53

Agency has two implications for one health. First, any salient specialized adaptations (e.g., grammatical language, capacity to detect cheaters in social contracts, creativity, specialized tool inventions and use) would presuppose capacities for agency, rather than mere species membership.Footnote 54 Neuroscience, in these respects, is beginning to define the (fuzzy) boundaries of interspecies capabilities, including the existence of other (nonhuman) cultures, and certain aspects of learning, communication, and problem-solving in animals that are indicative of agency.Footnote 55 But in neuroscience, in many cases, it is uncertain whether agency exists outside of human experience. And neuroethics has not determined interspecific interests either, yet. It is likely that whatever we discover in these respects, there will be nuances when comparing capacities between species.Footnote 56 A neuroethics approach to one health ethics would therefore suggest that functional neuroanatomy and behavioral analogies contribute to our understanding of agential capabilities and needs, in terms of defining objective health interests, and therefore the rights of and between species.Footnote 57

Second, mental states are inaccessible to physicalist-based study. So, inference and analogy imply that the comparative mental states might be generalizable to (some) other species, and these deductions require logical semblance through interconnectedness and interdependence (knowledge of evolution, biology, and ecology). Therefore, mind, self-awareness, or consciousness are ostensibly underpinning generic components of health; for example, mental illness, illness-induced unconsciousness, or an inclination to be healthy. So, insofar as one health in practice concerns the interests of different species connected to and affecting each other, agency would seem to be relevant to the objectivity of health.Footnote 58 Therefore, a neuroethics of one health presumes that “people” (qua human beings) and “animals” (qua [nonhuman] animals) have comparable health states. These health states can be described as connected or shared phenomena, which are suggestive of population or public health.Footnote 59 But, one health ethics, rather than an approach to the health determinants between human publics, is coextensively determinate of interspecific well-being.

A neuroethical approach to one health could target issues like pollution, which are disruptive, pervasive, and lasting events that undermine natural rights by manifesting as interspecific health determinants: Someone is responsible for its direct health effects, as well as its impact vitiating homes, communities, and environments. In response to these cultural transgressions and other naturally occurring disasters, an egalitarian approach to environmental health justifies, for example, creating a shared biobanking resource so that clinical and veterinarian data are collected and stored, so they can be used to co-investigate and mutually respond to such health impacts,Footnote 60 or support clinical responses such as vaccinating nonhuman animals in equal regard, so that health is improved for all agents in the affected space.Footnote 61

Although I consider a rights approach has merit, ultimately, as a grounds for progressive egalitarianism, it requires adherence to the ethical conditions for ethical agent–agent interactions (and the inferred obligations of ethical institutions),Footnote 62 irrespective of the isolated consequences for human interests: Agency requires that practical judgments are matters of freedom and well-being, so that animal health is potentially and practically an equal moral consideration. Interspecific rights are controversial because isogenous consistency would require, for example, changing the purpose of conservation policy and practice,Footnote 63 and potentially far-ranging shifts in our treatment of animals,Footnote 64 and (if agency is a valid critique of that treatment) would preclude many aspects of public health that we currently depend upon.Footnote 65 So, conflicts of rights might undermine cultural institutions that protect human rights.Footnote 66 Moreover, that would likely garner resistance in some sectors such as agriculture, husbandry, and medical research, thus undermining the progress made in practical one health to date.

Increasingly, however, such resistance may be seen as illogical and illegitimate.Footnote 67 If agency necessarily grounds mutual recognition of rights, then it also necessarily implicates forms of cooperation.Footnote 68 In ultrasocial cultures, these relationships are codified as norms or theories of justice, but prosociality is also found in nature.Footnote 69 So, if sociality (rather than an agency) is considered necessary and sufficient for moral status, then relying on the significance of social scalability should not also commit us to species chauvinism.Footnote 70 In this respect, it is becoming less prudent to exclude at least some nonhuman species as rights holders (if you like, as “social,” rather than ultrasocial animals), and, if interspecific agency is plausible it would narrow, if not collapse, the perceived moral gap between culture and nature. Arguably, as a result, one health and public health would then be part of the same justice discourse about the determinants of health.

One Health Ethics and Reasonable Environmentalism

Agency also underscores a practicable refocus on the reasonable connections made by human beings to natureFootnote 71: “Some form of anthropocentrism is a necessary presupposition of any moral theory or moral discourse: no agents, no morality.”Footnote 72 That is, to deny that we are rational is to deny that we are human; and, one might suppose, human beings require nature to flourish. Suppose, then, if there is no nature, there is no agency. This claim assumes that agency is evolved,Footnote 73 but although culture originates in biology (i.e., as a consequence of, and therefore found in nature, as the previous argument suggests), and it is passed on between generations and projected into the future, the focus shifts to how culture develops from knowledge, and is practiced ethically through trending values.Footnote 74 Specifically, “climate events and associated suffering can no longer be cast as acts of God or nature. They are now at least partly linked to human agency and responsibility.”Footnote 75 Such impacts on the environment are “the consequence, intended or otherwise, of decisions taken by human minds”Footnote 76; and measuring them is suggestive of the Anthropocene: that human action will be recorded in the geology of Planet Earth.Footnote 77

The “agential” perspective reminds us that “rational natures are not only agents but are on the receiving end of one another’s action. This presupposition is not self-evident: it holds only if rational natures lead connected lives, or (as Kant often puts it) ‘share a world.’”Footnote 78 In this respect, public health refers to all human beings by embedding “legal persons” in social and protected contexts in which they live (and the beings they live with).Footnote 79 That view is challenged by versions of environmental naturism, which considers nature to have an inherent value (to various degrees) and therefore that value should be material to what we do.Footnote 80 This conflict becomes obvious, for example, when public health necessarily excludes nonhuman species from practical considerations (such as culling policies).Footnote 81 In these contexts, public health’s only referent is the science of animal welfare, and is not meant to carry theoretical animal rights. In law, it is often the perceived connection a nonhuman species or individual animal has to humanity, or a particular human being, that creates responsibility, affords culpability, and provides a remedy.Footnote 82 Law in this sense is not for animals, but protects our special interests in them; likewise, environmental protection (mainly) benefits humans. Public health also defines public engagement as a method to articulate a political conception that accommodates a plurality of comprehensive doctrines, but it is not meant to speak to animal interests because it is not obvious that our interests “overlap.”Footnote 83 As such, a perceived irresolvable conflict between human health and animal welfare plausibly explains a traditional humanistic connection to nature.

One health ethics, however, is the emergent idea of reframing positive environmental change as the principle of natural connection: It necessarily connects culture to nature in the only world we know to exist.Footnote 84 The world is our (only) life support, and we know that. Moreover, since this fact is known, (morally) we have duties to modify our behavior to minimize or mitigate the negative impacts we have on an environment that we know other agents (or communities) inhabit. Footnote 85 Human agents, therefore, must look ahead to the things that are necessary for their and rationally, others’ well-being,Footnote 86 and recognize the impacts in their own actions and beliefs of causing or contributing to biodiversity loss, overconsumption of ecoservices, and capture of public goods.Footnote 87 It is in this respect that individuals have to reevaluate their relationship to nature, perhaps by first imagining a world without connections to green spaces, trees, grass, wilderness, and the creatures found there.Footnote 88 It is in this respect that one health ethics evokes the public interests, in the sense that our actions toward nature may be construed as (un)ethical (or [un]lawful) acts as they appeal to natural rights.Footnote 89 The scope of the public interest (as it is presently understood as a factor pertaining to human rights), however, suggests that the public good—and public bads—can only be generated by human activity: So, cultural artifacts are opportunities to support human well-being, and “captured goods” are such that they decrease our freedom.Footnote 90 One health ethics, for want of a better term, shifts considerations of the public interest to “the natural interest.” This theoretical contention is likely to puzzle one health practitioners and advocates in practice, but I wonder how else they can define a public interest that equally regards animal and environmental interests?

The indirect approach to environmental responsibility, rather than the direct application of rights, will always be subjective: yet, if “…the concept of ‘nature’ is more complex and abstract than it seems, the ecological crisis remains a concrete and empirical reality, now affecting everybody whatever be their vision of nature.”Footnote 91 Suffice to say that, although there is no one concept of ethical environmentalism acceptable to all (yet), perhaps inharmoniousness is itself of value if it has the practical consequence of trying out evermore environmentally friendly policies (i.e., groups achieve similar endpoints, but in different “theoretical” ways). But we should not rest easy on this pragmatic implication, if it is just as likely that the plurality of normative conceptions are themselves in relative conflictFootnote 92; we will still be left with such problems that affect all of humanity and the natural world, and a hodgepodge of possible solutions with relative, temporal, and contextual advantages and disadvantages.Footnote 93 These disagreements will then return to questions about how animals and the environment factor in “our” political and social solutions. But, as I have suggested, a philosophical approach to agency may get us closer to a coherent concept of one health. This approach allows the use of common philosophical tools such as “the principle of noncontradiction,” “consistency,” and “ought implies can” (“if you [ethically] should do X, then you [practically] can do X”Footnote 94: a practical rule that you cannot expect people to do something if it is not possible for them to do it, which, I think, speaks to the pitfalls of public health, too). These logical rules may have an impact on policy if embedded in ethical norms, thus making the case for environmentalism plausible, convincing, attractive, and possible, on grounds already established as reasonable. Much more work is needed in this regard, principally in the ways that the public interest defines the social value (the public good) of environmentalism, the specific function of cooperation between species, and the human species’ specific role in modern nature.Footnote 95

Finally, what I hope I have established is that agency creates a logical space for one health ethics coextensive to public health, so that both public health and one health ethics are compatible in the discourse about social regulation.Footnote 96 One health, therefore, becomes a lens—a perspective, personal narrative, and field of study—to identify actions that are hostile toward interspecies well-being, and reason to commit to better ways of living with nature.Footnote 97

Conclusion

Environmental dualism has been used in this article to differentiate a humanistic understanding of “cultural” rights, as specific to public health, from the naturalistic rights in one health. I have not attempted to settle the matter of dualism, but the dichotomy is illustrative of the fact that, in public health, nature has no value independent of providing healthy and sustainable ecoservices. Strong dualists claim that such services are meant to be used and potentially used up if replacements and alternatives are available. That can lead to exploitation and capture, regardless of temporal and contextual environmentally friendly outlooks bridging cultural and natural realms. These consequences have been underexplored in the ethics of one health.

My goal in this article is a call for recognition of the unique, essential, and necessary relationship agents have with nature, and, as such, to present an opportunity to foster better ways of living with and within it. One health is coextensive to public health, so it substantiates environmental responsibility as a public good, and frames public bads as collectively irresponsible or exploitative. In this respect, one health has two specific connotations. First, one health is a way to narrate the ethical conditions necessary to support natural phenomena as the public good. That suggests that there is necessarily interpersonal comparability between agents—and therefore potential interspecies comparability. The neuroscience of one health ethics, therefore, is grounded in an equal and equivalent ethical connection between the planet’s life support for all life and the environment’s cultural value to us. Second, one health is a theory of environmentalism: It is part of the neuroethical study of rational choice, and about discovering opportunities to live as a natural egalitarianist, to be expressive of the value of nature, and act mutually beneficially toward others living in shared natural spaces. Our gaze toward nature should therefore necessitate continuous, context-specific investigation to discover ways of (and barriers to) living, without costs and compromises, that forsake nature for purely humanistic imperatives. If outcomes are meant to be anthropocentric, in this regard, then they are properly described as public health.

25. Cultural environmentalism refers to an “ecology” of cultural production and creativity, that is, rooting sociality in the quality of the human environment, and protecting (“conservation” of) the public domain; see Boyle J. The second enclosure movement and the construction of the public domain. Law and Contemporary Problems 2003;66:33–74. My use of the term is also based on the traditional sense of environmentalism: a “political and ethical movement that seeks to improve and protect the quality of the natural environment through changes to environmentally harmful human activities; through the adoption of forms of political, economic, and social organization that are thought to be necessary for, or at least conducive to, the benign treatment of the environment by humans; and through a reassessment of humanity’s relationship with nature.” Elliott L.

33. For example, the rational nature of human beings and dolphins (Tursiops truncates) are “consciously” similar, but (for example) have quite different physiological needs. So that raises questions about how comparability between species accounts for their moral status and different experiences of “health”; see Herman L. Intelligence and rational behaviour in the bottlenosed dolphin. In: Hurley S, Nudds M, eds. Rational Animals? Oxford: Oxford University Press; 2006:439–67. Such deductions are not purely scientific observations, because, for instance, between and within species, categorical groupings often break down due to marginal, potential, proportional and future considerations. That is, the difference between temporal functional states—between human embryos and born human beings, inferred cognitive states of individuals, for example, sleeping or unconsciousness—or of the unusual, for example, Kanzi the bonobo (Pan paniscus), using human language; for background, see Lafollette H, Shanks N. The origin of speciesism. Philosophy 1996;71:41–61.

John Coggon claims that “the population the [public health] approach speaks to includes all born, living human beings within the jurisdiction of a Liberal State… and denies special normative protection to potential members that some theorist would include” (citing Peter Singer’s Animal Liberation); See note 39, Coggon 2012, at 212–13.

97. In this respect, universal goods identify the preconditions for all life. These objective, positive goods are relevant for all species, and, as such contrast with “public” or universal bads such as habitat loss. For example, humans require portable water, and Bottlenose dolphins (see note 33) require unpolluted seas, so that water—in this sense, as a basic good—benefits them both. However, trees also benefit from unpolluted ground water, thus suggesting the idea of water as a universal good. See note 61, Capps, Lederman 2015.
