Birds, Bats And Minds. Tales Of A Revolutionary Scientist: Donald R. Griffin. Volume Three, Carolyn A. Ristau

eBooks

In this three-volume biography, we revisit the life and accomplishments of the revolutionary scientist, Donald R. Griffin. He encountered a lifetime of initial hostile resistance to his ideas and studies; now they are largely accepted. He and a colleague discovered the phenomenon of echolocation used by bats to navigate and capture insects, proposed that birds navigate guided by such cues as the sun and stars, and suggested that animals are likely aware, thinking and feeling beings. Forty interviews with his colleagues and friends help us understand the young emerging scientist and the mature researcher. We learn about his and others’ …

Limits To Sentience, Donald M. Broom

Animal Sentience

There are many parallels between cellular function in animals and plants. Plants can have complex interactions with their environments. But they lack a central nervous system, which is a prerequisite for sentience (the capacity to feel). In my view the suggestion that plants are sentient is not only empirically incorrect but potentially harmful to the efforts to protect the welfare of sentient beings.

Highly Pathogenic Avian Influenza, Andrew N. Rowan, Kathleen Rowan

WellBeing News

The avian flu virus was the agent that caused the devastating worldwide influenza pandemic in 2018 that killed an estimated 50-100 million people, and health authorities continue to pay close attention to periodic outbreaks of avian flu. Currently, an H5N1 influenza virus is leading to millions of wild birds and domestic poultry deaths. Recently, this virus spread in a mink farm in Spain, raising the stakes that it might be able to spread among humans. While the current avian flu pandemic is a major economic problem for global farms and a major animal welfare concern for domestic poultry and wild …

Defining And Exploring Animal Sentience, Andrew N. Rowan, Joyce M. D'Silva Mrs, Ian J.H. Duncan, Nicholas Palmer

Animal Sentience

One of the commentaries on the target article notes that "animal sentience" is difficult to define operationally. This response to the commentaries develops a working, usable definition of animal sentience and examines the relationships between animal emotions and sentience.

Nexus Between Animal Welfare, Environment, And Sustainable Development: Resource Document, Wellbeing International

Nexus – UNEP – Animal Welfare, Environment, Sustainable Development

This Resource Document has been developed to explore the Nexus (links) between Animal Welfare, the Environment, and Sustainable Development. The document includes relevant citations and reports addressing the topics encompassed by the Nexus. It will be maintained as a “living document” (subject to revision) in the WellBeing International Studies Repository. The original document and subsequent revisions will be kept in the Repository to provide a record of the changes.

Defining And Assessing Sentience, Barry O. Hughes

Animal Sentience

Precisely what is meant by the term sentience and how does it overlap with being conscious? We accept that animals have feelings but how do we know what they are and can we measure them? It is important that we clarify the terminology underlying these difficult concepts. Over the last 50 years a scientific discipline has developed to tackle these questions in a systematic way. We have to avoid thoughtless anthropomorphism yet we have to try to relate sentience in animals, as appropriate, to corresponding experiences in humans.

Independence, Weight And Priority Of Evidence For Sentience, Elizabeth Irvine

Animal Sentience

This commentary maps out relationships of dependency between the criteria proposed in the target article (Crump et al. 2022), identifying the criteria that carry most of the weight of the evidence, and suggesting which criteria should have priority in research on sentience.

Strong Inferences About Pain In Invertebrates Require Stronger Evidence, Edgar T. Walters

Animal Sentience

Evidence for sentience in animals distantly related to humans is often sought in observations of behavioral and neural responses to noxious stimuli that would be painful in humans. Most proposed criteria for painful sentience in “lower” animals such as decapod crustaceans have no necessary links to the affective (“suffering”) component of pain. The best evidence for painful affect in animals is learned aversion to stimuli associated with noxious experience, and conditioned preference for contexts associated with relief from aversive consequences of noxious experience, as expressed in voluntary behavior. Such evidence is currently lacking for any invertebrate except octopus.

Emotional Component Of Pain Perception In The Medicinal Leech?, Brian D. Burrell

Animal Sentience

Crump et al. have provided a series of criteria to assess animal sentience that is focused on the perception of pain, which is known to have both sensory and emotional components. They also provide a qualitative scoring system to assess data that address the eight criteria and apply this paradigm to decapod crustaceans. The criteria laid out have the potential to be applied to other invertebrates typically thought to have sensory response to tissue damage, but no emotional component to pain perception.

The Question Is Not “Can Humans Talk?” Or “Can They Suffer?” But “Can They Reason?”, Clive Phillips

Animal Sentience

In their target article, Rowan et al (2022) make a welcome attempt to chart the development of Western progress over the past two hundred years toward formally recognizing that animals feel. They outline the heroic efforts of Compassion in World Farming to gain for animals the status of sentient beings rather than merely human property. A broader view exists, from human prehistory to the present day, in which animals have been (and still are) understood to be sentient by indigenous peoples as well as by some Eastern religions. Growing recognition in the West that animals feel represents a new age …

Why The Recognition Of Sentience Is So Important For Animal Welfare, Mark Jones

Animal Sentience

Rowan et al. (2022) provide a useful summary of the history and development of the philosophical, public, and legal recognition of animal sentience and its importance in improving the welfare of animals. Here I argue for the incorporation of the precautionary principle in sentience recognition, and the wider significance of sentience recognition to the current climate, biodiversity and human health crises.

Sentience And Sentient Minds, John Anthony Webster

Animal Sentience

My commentary builds on Rowan et al.’s (2022) comprehensive review to address the question ‘what do we mean by sentience?’ It suggests how we might recognise degrees of sentience within the animal kingdom, ranging from primitive sensations such as hunger and pain to more complex emotions that determine quality of life.

Heeding The Call Of Covid-19, David Wiebers, Valery Feigin

Animal Sentience

We are grateful to all of our commentators. They have provided a wide range of valuable perspectives and insights from many fields, revealing a broad interest in the subject matter. Nearly all the commentaries have helped to affirm, refine, expand, amplify, deepen, interpret, elaborate, or apply the messages in the target article. Some have offered critiques and suggestions that help us address certain issues in greater detail, including several points concerning industrialized farming and the wildlife trade. Overall, there is great awareness and strong consensus among commentators that any solution for preventing future pandemics and other related health crises must …

Extending Animal Welfare Science To Include Wild Animals, Walter Veit, Heather Browning

Animal Sentience

Ng’s (2016) target article built on his earlier work advocating a science of welfare biology (Ng 1995). Although there were problems with the models proposed in Ng’s original paper regarding the balance of pleasure and suffering for wild animals, his call for a science of wild animal welfare was a sound one. This does not require a new discipline but just an extension of the existing frameworks and methods of animal welfare science to include wild animals.

Animal Sentience: History, Science, And Politics, Andrew N. Rowan, Joyce M. D'Silva, Ian J.H. Duncan, Nicholas Palmer

Animal Sentience

This target article has three parts. The first briefly reviews the thinking about nonhuman animals’ sentience in the Western canon: what we might know about their capacity for feeling, leading up to Bentham’s famous question “can they suffer?” The second part sketches the modern development of animal welfare science and the role that animal-sentience considerations have played therein. The third part describes the launching, by Compassion in World Farming, of efforts to incorporate animal sentience language into public policy and regulations concerning human treatment of animals.

Intensive Animal Farming Conditions Are A Major Threat To Global Health, Cynthia Schuck-Paim

Animal Sentience

Wiebers & Feigin accurately propose that reducing the risks posed by infectious disease outbreaks and other global health challenges will depend critically on transitioning away from intensive animal farming practices. Creating the right incentive structure for this transition to happen is one of the great challenges in the years to come, but a much-needed step to ensure the health and well-being of current and future generations.

Individual Choices And Global Well-Being, Andrew N. Rowan

WellBeing News

The article focuses on how individuals might modify their behaviors as a critical part of helping to improve not only individual health and well-being, but also helping to reduce our impact on the world around us.

Brain Complexity, Sentience And Welfare, Donald M. Broom

Animal Sentience

Neither sentience nor moral standing is confined to animals with large or human-like brains. Invertebrates deserve moral consideration. Definition of terms clarifies the relationship between sentience and welfare. All animals have welfare but humans give more protection to sentient animals. Humans should be less human-centred.

What The Covid-19 Crisis Is Telling Humanity, David Wiebers, Valery Feigin

Animal Sentience

The planet is in a global health emergency exacting enormous medical and economic tolls. It is imperative for us as a society and species to focus and reflect deeply upon what this and other related human health crises are telling us about our role in these increasingly frequent events and about what we can do to prevent them in the future.

Cause: It is human behavior that is responsible for the vast majority of zoonotic diseases that jump the species barrier from animals to humans: (1) hunting, capture, and sale of wild animals for human consumption, particularly in live-animal markets; …

China's Lack Of Animal Welfare Legislation Increases The Risk Of Further Pandemics, Amanda Whitfort

Animal Sentience

Legislation enforcing positive animal welfare standards provides an important buffer against the spread of disease when other safeguards to promote animal health have failed. The continuing absence of animal welfare legislation in China increases the risk of future pandemics, like COVID-19, and puts animal health, and consequently public health in danger.

Rethinking Global Governance To Address Zoonotic Disease Risks: Connecting The Dots, Kelley Lee

Animal Sentience

Large-scale changes in human behaviour are urgently needed to prevent future pandemics involving zoonotic diseases such as COVID-19. However, this will not happen to the required degree, and with sufficient speed, without a major shift in how humanity collectively governs itself. Alongside a shift in focus from individual behaviours to the structural conditions underpinning the world economy that shape human behaviours, effective global governance presses us to connect more dots than ever before. The One Health approach is an important starting point but we need to go much further.

New Approach To Health And The Environment To Avoid Future Pandemics, Serge Morand

Animal Sentience

This commentary expands Wiebers & Feigin’s target article by pinpointing how declining wildlife, expanding livestock and globalisation contribute to the increase in epidemics of zoonotic diseases, the COVID-19 crisis and future health crises. Epidemics and the emergence of zoonoses are manifestations of dysfunctional links with animals, both wild and domestic, requiring a new approach to health and the environment.

Can Human Neurological Tests Of Consciousness Be Applied To Octopus?, Benedetta Cecconi, Jitka Annen, Steven Laureys

Animal Sentience

If the anatomy, physiology and behaviour of a species differ substantially from our own, can we infer that the species is unconscious? In the daily clinical care of patients with disorders of consciousness we face many similar challenges: our current approach with these patients - a combination of behavioural and brain imaging-based assessments - might also be a viable route to investigating octopus consciousness.

Whenever Possible, Treat The Cause: Shut Down The Flu Factories, Michael Greger

Animal Sentience

Over the last few decades -- and at a historically unprecedented rate -- hundreds of human pathogens have emerged, mostly from animals. The United Nations’ “Preventing the Next Pandemic” report blames increasing demand for animal protein and unsustainable agricultural intensification as two key drivers of the emergence of zoonotic threats. Animal agribusiness has become a viral disease incubator, but there is a clear path towards preventing the next pandemic as well as protecting planetary health: to reform the practice of raising domestic animals for food and to adopt eating habits that not only protect our health, but address …

Reflections On Psychological And Psychiatric Consequences Of Covid-19 Pandemic, Donatella Marazziti

Animal Sentience

Although far from reaching a clear conclusion, some evidence increasingly highlights the possible connections among climate change, environmental pollution and the current COVID-19 pandemic, as well as their intertwined detrimental effects on both physical and mental health. Such a catastrophic event calls for a novel awareness of the interdependence of all biotic and nonbiotic factors in our environment and planet.

Remedying Anthropogenic Zoonoses, Daniela Figueroa, Ximena Duprat

Animal Sentience

Abstract: Zoonotic diseases represent 60% of the infections suffered by the human species. in light of the latest episodes of epidemics and pandemics we have to begin to address health problems with another perspective. The “One Health” vision aims to generate a change in consciousness and a new working strategy.

The Necessity Of Human Attitude Change And Methods Of Avoiding Pandemics, Donald M. Broom

Animal Sentience

Humans share their biology with other animals and in each of their actions should consider the consequences for all life. A series of measures can be taken by governments and individuals that would minimise inter-specific transfer of pathogens from wildlife and reduce the development of antimicrobial resistance.

One Welfare, The Role Of Health Professionals, And Climate Change, Anne Fawcett

Animal Sentience

Wiebers & Feigin argue that the COVID-19 crisis is a call for humanity to rethink our relationships with animals and the environment. This One Welfare approach has implications for the role of health care professionals and demands that we address climate change.

Plant-Based Diets And Covid-19: Those Who Harvest Crops Are At High Risk, Jarret S. Lovell

Animal Sentience

This commentary extends Wiebers & Feigin’s (2020) plea to adopt diets that are less dependent on animals by calling on experts and activists to work for change with regard to farm worker labor conditions. Already doing among the most dangerous jobs, farmworkers are at increased risk of COVID-19. As we increasingly transition to plant-based diets, we must all ensure that farmworkers have safe and just working conditions to meet the demands of our changing diets.

Anthropogenic Suffering Of Farmed Animals: The Other Side Of Zoonoses, Jean-Jacques Kona-Boun

Animal Sentience

Wiebers & Feigin’s (W&F’s) target article warns of the zoonotic threat to human health from factory farming and urges phasing out meat production and consumption, for the benefit of both human and nonhuman animals. This commentary focuses on the physical and emotional suffering of farmed animals. This varies by species, production system and geographic location, but suffering is there throughout all stages of production — breeding, housing, transport, usage and slaughter. Ubiquitous monitoring of all facilities where farmed animals are kept, with surveillance cameras recording all phases of production would help reduce some forms of suffering. Other forms are caused …
