15 years of microbial biotechnology: the time has come to think big—and act soon

Our epoch is largely characterized by the growing realization and concern about the reality of climate change and environmental deterioration, the surge of global pandemics, the unacceptable inequalities between developed and underdeveloped countries and their unavoidable translation into messy immigration, overpopulation and food crises. While all of these issues have a fundamentally political core, they are not altogether removed from the fact that Earth is primarily a microbial planet and microorganisms are the key agents that make the biosphere (including ourselves) function as it does. It thus makes sense that we bring the microbial world—that is the environmental microbiome—to the necessary multi-tiered conversation (hopefully followed by action) on how to avoid future threats and how to make our globe a habitable common house. Beyond discussion on governance, such a dialogue has technical and scientific aspects that only frontline microbial biotechnology can help to tackle. Fortunately, the field has witnessed the onset of new conceptual and material tools that were missing when the journal started.     

Take a stand commentary: how can medical anthropologists contribute to contemporary conversations on "illegal" im/migration and health?

Of the estimated 214 million people who have migrated from poorer to richer countries in search of a better life, between 20 and 30 million have migrated on an unauthorized, or "illegal," basis. All have health needs, or will in the future, yet most are denied health care available to citizens and authorized residents. To many, unauthorized im/migrants' exclusion intuitively "makes sense." As scholars of health, social justice, and human rights, we find this logic deeply flawed and are committed to advancing a constructive program of engaged critique. In this commentary, we call on medical anthropologists to claim an active role in reframing scholarly and public debate about this pressing global health issue. We outline four key theoretical issues and five action steps that will help us sharpen our research agenda and translate ourselves for colleagues in partner disciplines and for broader audiences engaged in policymaking, politics, public health, and clinical practice.     

The evolutionary roots of our environmental problems: toward a Darwinian ecology

It is widely acknowledged that we need to stabilize population growth and reduce our environmental impact; however, there is little consensus about how we might achieve these changes. Here I show how evolutionary analyses of human behavior provide important, though generally ignored, insights into our environmental problems. First, I review increasing evidence that Homo sapiens has a long history of causing ecological problems. This means that, contrary to popular belief, our species' capacity for ecological destruction is not simply due to "Western" culture. Second, I provide an overview of how evolutionary research can help to understand why humans are ecologically destructive, including the reasons why people often overpopulate, overconsume, exhaust common-pool resources, discount the future, and respond maladaptively to modern environmental hazards. Evolutionary approaches not only explain our darker sides, they also provide insights into why people cherish plants and animals and often support environmental and conservation efforts (e.g., Wilson's "biophilia hypothesis"). Third, I show how evolutionary analyses of human behavior offer practical implications for environmental policy, education, and activism. I suggest that education is necessary but insufficient because people also need incentives. Individual incentives are likely to be the most effective, but these include much more than narrow economic interests (e.g., they include one's reputation in society). Moralizing and other forms of social pressure used by environmentalists to bring about change appear to be effective, but this idea needs more research. Finally, I suggest that integrating evolutionary perspectives into the environmental sciences will help to break down the artificial barriers that continue to divide the biological and social sciences, which unfortunately obstruct our ability to understand ourselves and effectively address our environmental problems.     

Ecological Aging: The Settings Approach in Aged Living and Care Accommodation

As the proportion of older people increases within populations, financial demands related to the cost of health service delivery threaten global stability. This population trend challenges the traditional approach to health service delivery to older populations. This article presents the Australian context as a case study to argue that the application of a health promoting settings approach to aged care may lead to improved well-being for older people to the extent that the periods of chronic morbidity often associated with aging can be compressed into an ever shorter period of time. Promoting an ecological perspective to aged care suggests that there is no need to manage older people in isolation, as is common practice, but as integral to the way society lives, works, and plays. The article maps parallels between characteristics of health promoting settings such as Health Promoting Schools and the aged living and care industry, arguing that the setting encompassing services for the elderly is a prime location for the establishment of a new health promotion setting. Supporting life opportunities for our aged is central to such an approach. More broadly, an ecological approach orients us toward the connection between environment and health, and encourages increased attention and action within the aged living and care sector on reducing environmental impacts of this growing population. As such, the application of this approach to the aged living and care sector has the potential to reduce the threat that a dependant older population has on global sustainability.     

Cognitive neuroscience of human social behaviour

We are an intensely social species--it has been argued that our social nature defines what makes us human, what makes us conscious or what gave us our large brains. As a new field, the social brain sciences are probing the neural underpinnings of social behaviour and have produced a banquet of data that are both tantalizing and deeply puzzling. We are finding new links between emotion and reason, between action and perception, and between representations of other people and ourselves. No less important are the links that are also being established across disciplines to understand social behaviour, as neuroscientists, social psychologists, anthropologists, ethologists and philosophers forge new collaborations.     

Maximizing biodiversity, information and sustainability

Numerous global changes—notably anthropogenic extinction—force reconsideration of our management practices and the ways we regulate human influence in today’s world. Here, I define management to maximize biodiversity and illustrate the science that provides information to set goals for such management. Maximizing biodiversity simultaneously achieves sustainability and systemic health by avoiding the abnormal or pathological. The normal or sustainable are determined through the use of empirical integrative patterns to objectively account for the complexity of systems within which we find ourselves as a species. The science that reveals these integrative patterns provides measures of problems that can be solved by maximizing biodiversity—problems heretofore recognized only qualitatively. I use the Shannon-Weiner information index to test, and, with no surprise, reject the null hypothesis that there is no direct anthropogenic effect on biodiversity. The results of this science serve as examples of the kind of information most useful for guiding management and illustrate maximized biodiversity as a standard for management. Reference points based on maximized biodiversity are preferable to statistical parameters in meeting the objective of avoiding the abnormal or pathological in our interactions with other species, ecosystems and the biosphere. Management to maximize biodiversity is implemented by modifying human interactions with other biotic systems to achieve consistency in such interactions by mimicking natural role models of sustainability. Human influence is a significant factor in today’s world and the magnitude of such influence is illustrated by comparing humans with other species.     

Forest Remnants Along Urban-Rural Gradients: Examining Their Potential for Global Change Research

Over the next century, ecosystems throughout the world will be responding to rapid changes in climate and rising levels of carbon dioxide, inorganic N and ozone. Because people depend on biological systems for water, food and other ecosystem services, predicting the range of responses to global change for various ecosystem types in different geographic locations is a high priority. Modeling exercises and manipulative experimentation have been the principle approaches used to place upper and lower bounds on community and ecosystem responses. However, each of these approaches has recognized limitations. Manipulative experiments cannot vary all the relevant factors and are often performed at small spatio-temporal scales. Modeling is limited by data availability and by our knowledge of how current observations translate into future conditions. These weaknesses would improve if we could observe ecosystems that have already responded to global change factors and thus presage shifts in ecosystem structure and function. Here we consider whether urban forest remnants might offer this ability. As urban forests have been exposed to elevated temperature, carbon dioxide, nitrogen deposition and ozone for many decades, they may be ahead of the global change “response curve” for forests in their region. Therefore, not only might forests along urbanization gradients provide us with natural experiments for studying current responses to global change factors, but their legacy of response to past urbanization may also constitute space-for-time substitution experiments for predicting likely regional forest responses to continued environmental change. For this approach to be successful, appropriate criteria must be developed for selecting forest remnants and plots that would optimize our ability to detect incipient forest responses to spatial variation in global change factors along urbanization gradients, while minimizing artifacts associated with remnant size and factors other than those that simulate global change. Studying forests that meet such criteria along urban-to-rural gradients could become an informative part of a mixed strategy of approaches for improving forecasts of forest ecosystem change at the regional scale.     

Healing across Cultures: Learning from Traditions

The health and wellness of an individual are reliant on the integrated effects of mind, body, and spirit. This triad is intricately set within a backdrop of the environment, our earth. Western cultures often disregard this holism, especially this fourth component, in its considerations of wellness as described by modern medicine. This practice is unlike that of many of the traditional cultures in the world. These cultures focus more on balance in the context of environmental respect. Varied cultures share remarkable similarities in their healing modalities, especially considering the relative isolation from one to another—evidence that there is truth to the healing knowledge they possess. We are not disconnected from the natural world in terms of health, but dependent and interconnected within ourselves and to everything around us. Social change is required to assure that the practice of modern medicine evolves to incorporate this integral aspect of health and wellness, and this can be done through partnerships with traditional healers.There is a growing demand for wellness and earthly responsibility. It is time to appropriately learn from age-old societies and their healing traditions for they do have answers we are seeking in sustainability and harmony, environmental stewardship and planetary respect, and holistic health. For thousands of years, our ancestors have known the secrets of long life—this knowledge needs to be preserved through the apprenticeship of future generations. We propose a collaboration that develops mutually beneficial learning partnerships combining modern medical knowledge with the wisdom of traditional healers around the world.     

Transdisciplinary research and clinical priorities for better health

Modern medicine makes it possible for many people to live with multiple chronic diseases for decades, but this has enormous social, financial, and environmental consequences. Preclinical, epidemiological, and clinical trial data have shown that many of the most common chronic diseases are largely preventable with nutritional and lifestyle interventions that are targeting well-characterized signaling pathways and the symbiotic relationship with our microbiome. Most of the research priorities and spending for health are focused on finding new molecular targets for the development of biotech and pharmaceutical products. Very little is invested in mechanism-based preventive science, medicine, and education. We believe that overly enthusiastic expectations regarding the benefits of pharmacological research for disease treatment have the potential to impact and distort not only medical research and practice but also environmental health and sustainable economic growth. Transitioning from a primarily disease-centered medical system to a balanced preventive and personalized treatment healthcare system is key to reduce social disparities in health and achieve financially sustainable, universal health coverage for all. In this Perspective article, we discuss a range of science-based strategies, policies, and structural reforms to design an entire new disease prevention–centered science, educational, and healthcare system that maximizes both human and environmental health.

Luigi Fontana and co-authors discuss present and future challenges, and possible solutions, for global health and health care provision.

Environmental degradation, global warming, and rising pollution are impairing planetary health even as lifestyle- and age-related chronic diseases and emerging infectious diseases are devastating human lives. These are among the greatest challenges facing society today, since people are living longer but often not healthier lives. More than 65% of people over 65 years have 2 or more chronic diseases [1,2]. The current epidemic of obesity, beginning in children, is laying the foundation for even greater problems in the near future, including a reduction in healthy life expectancy. Governmental health expenditure as a percentage of gross domestic product is expected to more than double by 2050, making many existing health funding models unsustainable [3]. Additionally, the present medical approach to chronic diseases in the United States and other affluent countries has vast consequences on planetary health and global economic development. In brief, this reactive “sick-care” medical system is not efficient, equitable, or even viable. Similar problems are now affecting low-income countries, where the epidemiological transition to noncommunicable diseases is coupled with a still high incidence of infectious diseases, dramatic environmental dilapidation, lack of medical resources, and limited support for social and health promotion activities, resulting in increasing inequalities and poverty.     

Greater goods: ethics,energy, and other-than-human speech

Renewable energy projects are ethically laudable for their cleansing intentions, but they also produce effects upon other-than-human beings in their orbit. Taking the case of Mexico's Isthmus of Tehuantepec, which is home to the densest concentration of on-shore wind parks anywhere in the world, and following Foucault's reading of the speech form ‘parrhesia’, this essay argues that the bodies of affected nonhuman beings, particularly those whose existence is actively balanced against a ‘greater good’ for humanity, enact a form of other-than-human speech, first in their threatened status and, secondly, through environmental management regimes that seek to synchronize human and nonhuman lives in settings of both local and global ecological failures.     

Global alteration of freshwaters: influences on human and environmental well-being

Human and environmental well-being—including disease resistance or avoidance, good nutrition, and species-appropriate population dynamics—are congruent with sustained healthy conditions. Unfortunately, hydrological alterations designed to benefit human societies often have unintended—and sometimes severe—consequences for the environment and the biodiversity it supports, and hence affecting billions of people. Improving this situation necessitates new water-resource developments, better water-use efficiency, and a reduction of contamination. Overall, the influences of existing and future freshwater (FW) regimes on human and environmental well-being are varied and wide-ranging. Furthermore, the scale is daunting: >1 billion people currently live in basins likely to require river management interventions for climate change alone. Global declines in FW biodiversity, in the nutritional value, and abundance of harvestable FW and riparian products, as well as deterioration in habitat quality for many species, require solutions; as do ongoing increases in the spread of FW-related diseases and non-native species. Modifications to FWs are now manifested in population declines and non-sustainable demographics for many aquatic species, as well as in deterioration of human health. In response, scientists, policy-makers, and water users are beginning to conceptualize FWs in terms of a global water system (GWS) to better understand and manage anthropogenic impacts. This involves identifying the ecological and policy implications of changes to the GWS, establishing international programs to understand and resolve major social and environmental issues arising from those changes, and developing broad-based mitigation or restoration techniques (e.g., environmental flow methodologies). Achieving these goals is paramount for maintaining human health as well as for the FW ecosystems upon which we depend.     

The logical structure of dreams and their relation to reality.

The contradictions and non sequiturs often found in dreams (or, equivalently, dream-narratives) are not in fact logical errors, but express and work with a type of logic that characterizes the deepest dimensions of our waking reality. These are the dimensions in which we deal with ourselves as a whole, our lives as a whole, or with the sense of reality as a whole. We do so, for example, in situations of deep personal transformation, or of recognition of deep difference of outlook. The paper argues that the logic of these situations is validly one of contradiction and non sequitur, that dreams sometimes express and work with these kinds of situations, and that these kinds of dreams therefore validly involve the same kind of logic. These kinds of dreams consequently also express insight into the sense that our lives or existence as a whole has for us. In achieving that insight, they actively orient, situate, or resituate us in our relation to our lives or existence as a whole. In this respect they are in themselves a practice of philosophy.

Genomics and the Ark: an ecocentric perspective on human history

Views of ourselves in relationship to the rest of the biosphere are changing. Theocentric and anthropocentric perspectives are giving way to more ecocentric views on the history, present, and future of humankind. Novel sciences, such as genomics, have deepened and broadened our understanding of the process of anthropogenesis, the coming into being of humans. Genomics suggests that early human history must be regarded as a complex narrative of evolving ecosystems, in which human evolution both influenced and was influenced by the evolution of companion species. During the agricultural revolution, human beings designed small-scale artificial ecosystems or evolutionary "Arks," in which networks of plants, animals, and microorganisms coevolved. Currently, our attitude towards this process seems subject to a paradoxical reversal. The boundaries of the Ark have dramatically broadened, and genomics is not only being used to increase our understanding of our ecological past, but may also help us to conserve, reconstruct, or even revivify species and ecosystems to whose degradation or (near) extinction we have contributed. This article explores the role of genomics in the elaboration of a more ecocentric view of ourselves with the help of two examples, namely the renaissance of Paleolithic diets and of Pleistocene parks. It argues that an understanding of the world in ecocentric terms requires new partnerships and mutually beneficial forms of collaboration and convergence between life sciences, social sciences, and the humanities.     

Is the unified list system for organ transplants fair? Analysis of opinions from different groups in Brazil

In the 1960s, when Dr. Belding Scribner discovered how to accomplish the process of dialysis in a repeated way, he could not imagine that in solving such a problem others as or more difficult would appear. Given the technological progress and the impossibility of assisting all patients through the most modern methods, the medical doctor often finds himself faced with the moral dilemma of choosing which patient in the waiting list will receive the treatment. This same dilemma is amplified in the case of organ transplants. Professionals, students, professors of the juridical and health fields, and the population in general, were interviewed as a means of documenting the moral concepts and opinions surrounding this problem. In the reality in which we find ourselves, it seems to us that deciding who lives, and the responsibility for all the events that culminate in such decisions, is still a subject left open to discussion.     

Recent patents in plant biotechnology: impact on global health

Agricultural biotechnology offers a robust series of tools by which to address global concerns such as food security, crop protection, and fuel/energy requirements. A number of advances made recently in plant molecular biology also have resulted in applications which largely focus on improving global human health. This review describes some of the recent innovations in plant biotechnology that have come to the forefront over the past year. Included are novel techniques by which plants can be improved as platforms for biopharmaceutical protein production, a growing field also referred to as 'molecular pharming'. The metabolic engineering of plants to produce compounds which have additional nutritional benefits is also outlined. The review concludes with a discussion of the future impact that these innovations may have both on global health and on the development of our future intellectual property landscape.     

On Agonising: Street Charity and First Ethics

To agonise is to “undergo great mental anguish through worrying about something,” according to the New Oxford Dictionary of English. I suggest that agonising in this sense is a fundamental response to any ethical dilemma. It has a long intellectual and literary lineage. In this essay, I agonise over the dilemmas posed by street beggars, their intrusiveness and their appeal to our intuitive sense of social duty. I explore the discomfort we may feel at their presence, and the value that discomfort may have for the evolution of our ethical lives.     

Of bonds and boundaries: what is the modern role of anthropomorphism in primatological studies?

Anthropomorphism (and its obverse, zoomorphism) continues to shift and propel us toward changing perspectives on ourselves and other animals. Discussions of anthropomorphism in primate behavior are ostensibly about our use and definition of terms, but ultimately reflect our views of what is unique to humans or unknowable in other animals. Primatologists doing long-term fieldwork report on the bonds that are inevitably formed through familiarity with their study subjects and how anecdotes and anthropomorphism help them to gain a contextualized view of animal lives. This fuller view of animal society serves as an aid to understanding different rationalities and provides a more effective modern role for anthropomorphism than does seeking to demonstrate isomorphic capacities in alloprimates. Although most ordinary language terms are accepted among primatologists, "primate culture" serves as an example of a term and a concept that overreached acceptable anthropomorphic limits when defined to accord with definitions of modern human culture. Comparing similar behavioral forms as the product of similar selective pressures acting on specific early traits, producing homoplasies through convergent evolution, provides a nonanthropomorphic basis for seeking similarities in human and alloprimate behavior.     

From “Us vs. Them” to “Shared Risk”: Can Animals Help Link Environmental Factors to Human Health?

Linking human health risk to environmental factors can be a challenge for clinicians, public health departments, and environmental health researchers. While it is possible that nonhuman animal species could help identify and mitigate such linkages, the fields of animal and human health remain far apart, and the prevailing human health attitude toward disease events in animals is an “us vs. them” paradigm that considers the degree of threat that animals themselves pose to humans. An alternative would be the development of the concepts of animals as models for environmentally induced disease, as well as potential “sentinels” providing early warning of both noninfectious and infectious hazards in the environment. For such concepts to truly develop, critical knowledge gaps need to be addressed using a “shared risk” paradigm based on the comparative biology of environment–host interactions in different species.     

Loneliness,Depression, and Physical Activity in Older Adults: The Therapeutic Role of Human–Animal Interactions

ABSTRACT

The global population of older persons is projected in 2050 to reach approximately 2.1 billion. As people age, feelings of loneliness, depression, and physical inactivity often occur due to a multitude of reasons. These feelings may manifest and cause adverse health outcomes. With the predicted increase of older adults worldwide, the prevalence of loneliness, depression, and physical inactivity may also worsen over time if unattended. Since older adults are subject to psychological and physical changes as they age, it is important to find creative ways to address the health needs of this growing population. Therefore, interventions are needed to prevent or decrease the psychological and physical challenges that older adults face. This paper examines existing literature on human–animal interactions (HAIs) in the lives of older adults in relation to concepts such as loneliness, depression, and physical activity. The psychological and physical health benefits of animals for older adults include decreased loneliness and depression, improved cardiovascular health, and increased physical activity. There is mounting evidence supporting the therapeutic psychological and physical health benefits of animals in the lives of older adults. However, there are practical and financial implications that must be considered. Methodological considerations and future directions for human–animal interaction research with older adults are also discussed.     

What Justifies a Future with Humans in It?

Antinatalist commentators recommend that humanity bring itself to a close, on the theory that pain and suffering override the value of any possible life. Other commentators do not require the voluntary extinction of human beings, but they defend that outcome if people were to choose against having children. Against such views, Richard Kraut has defended a general moral obligation to people the future with human beings until the workings of the universe render such efforts impossible. Kraut advances this view on the grounds that we are obliged to exercise beneficence toward others and on the grounds that the goods available in human lives are morally compelling. This account ultimately succeeds in making no more than a prima facie defense of human perpetuation because considerations of beneficence could override – in some cases probably should – override any duty to perpetuate human beings. While the goods of human life may be distinctive, they cannot serve as reason‐giving in regard to their own perpetuation. Ironically, the exercise of beneficence may authorize the extinction of human beings, if it becomes possible to enhance the goods available to human descendants in a way that moves them away from human nature as now given. The defense of a morally obligatory and strictly human future remains elusive, even as it becomes morally desirable to work against Fateful Catastrophes, those human‐caused events that threaten to extinguish existing lives already good and enriching for their bearers.
