Background extinction is a natural phenomenon. Anthropogenic biodiversity loss has been addressed from the various view points. The debate is continuing to identify the root cause of the anthropogenic mass extinction, also called the sixth extinction. The present communication discusses various anthropogenic drivers of the biodiversity loss and explains the ongoing sixth mass extinction using Garrett Hardin's “the tragedy of the commons”. Such explanations provide options for policy makers and for us to save the precious biodiversity of our planet. It has been demonstrated that presently we share about one third of the Net Primary Productivity which must be reduced through reducing our food consumption and by reducing our utilization of energy. Promotion of sustainable human behaviours to ameliorate the problem of anthropogenic extinction or the sixth extinction has been discussed in the light of recent findings from neurobiology and molecular biology. Biodiversity conservation through providing benefit to the people may be effective conservation strategies which would save the interest of human civilizations as well as other life forms on the earth.

A global extinction crisis may threaten the survival of most existing life forms. Influential discourses of ‘existential risk’ suggest that human extinction is a real possibility, while several decades of evidence from conservation biology suggests that the Earth may be entering a ‘sixth mass extinction event’. These conditions threaten the possibilities of survival and security that are central to most branches of International Relations. However, this discipline lacks a framework for addressing (mass) extinction. From notions of ‘nuclear winter’ and ‘omnicide’ to contemporary discourses on catastrophe, International Relations thinking has treated extinction as a superlative of death. This is a profound category mistake: extinction needs to be understood not in the ontic terms of life and death, but rather in the ontological context of be(com)ing and negation. Drawing on the work of theorists of the ‘inhuman’ such as Quentin Meillassoux, Claire Colebrook, Ray Brassier, Jean-Francois Lyotard and Nigel Clark, this article provides a pathway for thinking beyond existing horizons of survival and imagines a profound transformation of International Relations. Specifically, it outlines a mode of cosmopolitics that responds to the element of the inhuman and the forces of extinction. Rather than capitulating to narratives of tragedy, this cosmopolitics would make it possible to think beyond the restrictions of existing norms of ‘humanity’ to embrace an ethics of gratitude and to welcome the possibility of new worlds, even in the face of finitude.

Extinction of species has been a recurrent phenomenon in the history of our planet, but it was generally outweighed in the course of quite a long geological time by the appearance of new species, except, especially, for the five geologically short times when the so-called “Big Five” mass extinctions occurred. Could the current decline in biodiversity be considered as a signal of an ongoing, human-driven sixth mass extinction? This note briefly examines some issues related to: (i) The hypothesized current extinction rate and the magnitude of contemporary global biodiversity loss; (ii) the challenges of comparing them to the background extinction rate and the magnitude of the past Big Five mass extinction events; (iii) briefly considering the effects of the main anthropogenic stressors on ecosystems, including the risk of the emergence of pandemic diseases. A comparison between the Pleistocene fauna dynamics with the present defaunation process and the cascading effects of recent anthropogenic actions on ecosystem structure and functioning suggests that habitat degradation, ecosystem fragmentation, and alien species introduction are important stressors increasing the negative impact on biodiversity exerted by anthropogenic-driven climate changes and their connected effects. In addition, anthropogenic ecological stressors such as urbanization, landscapes, and wildlife trade, creating new opportunities for virus transmission by augmenting human contact with wild species, are among the main factors triggering pandemic diseases.

nearer than breathing, closer than hands and feet—George Morrison, “The Reawakening of Mysticism”Ecological criticism and queer theory seem incompatible, but if they met, there would be a fantastic explosion. How shall we accomplish this perverse, Frankensteinian meme splice? I'll propose some hypothetical methods and frameworks for a field that doesn't quite exist—queer ecology. (The pathbreaking work of Catriona Sandilands, Greta Gaard, and the journal Undercurrents must be acknowledged here.) This exercise in hubris is bound to rattle nerves and raise hackles, but please bear with me on this test flight. Start with the basics. Let's not create this field by comparing literary-critical apples and oranges. Let's do it the hard way, up from foundations (or unfoundations). Let's do it in the name of ecology itself, which demands intimacies with other beings that queer theory also demands, in another key. Let's do it because our era requires it—we are losing touch with a fantasy Nature that never really existed (I capitalize Nature to make it look less natural), while we actively and passively destroy life-forms inhabiting and constituting the biosphere, in Earth's sixth mass extinction event. Giving up a fantasy is even harder than giving up a reality.

This article unites recent writing in extinction studies with work in political ecology, justice theory and museum studies to explore qualitative, cultural approaches to extinction. I examine the role of storytelling and the power of narratives in addressing nonhuman extinction. Analysing the case study of a permanent gallery on extinction, evolution and biodiversity loss – the Survival Gallery of the National Museum of Scotland – I utilise a more-than-textual approach to narrative analysis. This paper explores the diverse ways in which the gallery relates stories of ‘natural’ extinction to the contemporary anthropogenic ‘Sixth Mass Extinction’. The Survival Gallery narrates a remarkably complex compilation of extinction stories, but the gallery’s narrative avoids areas of conflict or controversy, obscures justice concerns and ultimately presents a problematic depiction of a universalised humanity. Using this analysis of museum extinction storytelling, the paper contributes to emerging conceptualisations of multispecies justice frameworks. The article explores the possibilities and challenges of museum storytelling in grappling with complicated pasts and envisioning potential futures of survival, coexistence and flourishing. The paper concludes by considering how a multispecies justice approach to narrating extinction (and other entangled ecological-social phenomena) might flourish within and beyond museums.

AbstractAn Eclipse is an astronomical event that convenes a large audience. Few days before it, most of the community is aware of the event and the press is activated fully on it. The alignment recovers our most intrinsic human aspects, the curiosity, and enthusiasm for a natural phenomenon. This work is focused to enjoy and perceive it in three different ways: visually, listening, and in an artistic expression.We focused on the construction of more than one hundred LightSound devices, which the main purpose is to record the light intensity and transform it into different tones. Besides, we created an artistic representation of the Eclipse motivated by the ancestral culture of the people residing in the totality zone. This music adds a sensorial joy to the eclipse event.

The author in his article analyzes of the natural phenomenon that is reflected in oral legends named luu unzhikh (‘tornado’) on the materials of Mongolian Folklore samples and on the basis of the analysis of oral testimonies of the people who witnessed or heard about it, gives a scientific evaluation and specifies terminology. When analyzing the natural phenomenon that Mongols call luu unzhikh and reflect in legends it can be described as ‘a strong whirlwind that emerges in thundercloud, vertical to ground surface and sometimes detours irregular axis forming a vortex”.

In Taiwan, abortion was legalized in 1984. This paper examines the voices surrounding abortion expressed by monasteries in Humanistic Buddhism, a prominent Buddhist philosophy practiced in modern Taiwan. Humanistic Buddhism emphasizes that it is a “religion of the people.” However, in addition to the law of karma and causality, the value of all life forms is prioritized based on the ethics of “non-harming (ahimsā).” When some monasteries insist that abortion is killing, resulting in karmic retribution, some express sympathy with a woman’s decision to abort. When some monasteries promote a newly popularized ritual to appease aborted fetuses, some are keenly critical of the exploitation of women and manipulation of scriptures. Through a discursive analysis, this paper demonstrates the wide spectrum of Buddhist narratives in response to reproductive politics embedded in the conflicts between modernity and tradition, as well as locality and globality.

This paper discusses different geopolitical approaches to the causes of war. It starts by setting forth the historical relationship between geopolitics and warfare through different authors’ contributions to introduce the main explanations of this matter. In this way, we analyze the role of geography in warfare and its impact on conflicts. That leads us to the organicist perspective, which considers the expansion of the State a natural phenomenon that engenders war. Besides, physical geography also influences war outbreak. The second approach is the disposition of emerged land, which argues that specific places are prone to warfare due to their strategic location. The third approach is the accidental view. Its authors contend that war depends on the geographical distance between countries and border conflicts. Finally, we develop a new perspective based on geopolitical fragmentation to explain the war in modern Europe. This view explores the importance of fragmentation in the formation of the modern State and the shaping of an anarchical environment with the birth of the State’s system. Warfare became a trait of the international system because the modern State was born to wage war, and it became the dominant institution. Therefore, geopolitical fragmentation is the root cause behind violence between States in modern Europe.

AbstractPolicy-makers define our lives to a great extent, and are therefore the people everybody wants to talk to. They receive hundreds of messages in various forms day-by-day with the aim of making them decide for or against something. They are in an especially difficult situation as regards the so-called “wicked” or “diffuse” problems such as climate change and biodiversity loss (Millner and Olivier, 2015; Sharman and Mlambo, 2012; Zaccai and Adams, 2012). These problems are limitedly tackled at the policy level despite their major socio-economic and environmental implications, which is often explained by their complexity with a sense of remoteness of effects (Cardinale et al., 2012; WWF, 2018). Communicating advocacy or scientific messages of biodiversity is therefore both a challenge and an under-researched topic (Bekessy et al., 2018; Posner et al., 2016; Primmer et al., 2015; Wright et al., 2017), where both social and natural sciences and both scientists and practitioners are needed to contribute (Ainscough et al., 2019). In order to be successful in delivering messages, communication not only needs to be self-explanatory and easy to consume but novel as well. It additionally helps if the message arrives in a more extraordinary format to draw even more attention. Based on experiences drawn from a conservation and advocacy NGO’s work, this chapter will divulge various socio-economic theories about creative methods, communication, and influencing decision-makers through a campaign fighting for the preservation of key nature legislation. It will be demonstrated how different EU policy-makers, including representatives of the European Commission and Members of the European Parliament, the general public, and other stakeholders, were addressed with various messages and tools (e.g., short films, social media campaigns, fact sheets, involvement of champions). In addition to other key factors such as public support, knowledge of the target audience and political context, the probable impacts and limitations of these messages will also be elaborated. The relevance to the integration and employment of better socio-economic theories into improving communication is straightforward. It is crucial to tailor-make future advocacy work of “wicked problems” such as biodiversity loss and climate change, since these are not usually backed up by major lobby forces and are, therefore, financed inadequately compared to their significance. Understanding the way in which policy-makers pick up or omit certain messages, as well as what framing, methods and channels are the most effective in delivering them to the policy-makers, is pivotal for a more sustainable future.

Leaf temperature (Tleaf) influences photosynthesis and respiration. Currently, there is a growing interest on including lianas in productivity models due to their increasing abundance, and their detrimental effects on net primary productivity in tropical environments. Therefore, understanding the differences of Tleaf between lianas and trees is important for future of forest on whole ecosystem productivity. Here we determined the displayed leaf temperature (Td= Tleaf – ambient temperature) of several species of lianas and their host trees during ENSO and non-ENSO years to evaluate if the presence of lianas affects the Td of their host trees, and if leaves of lianas and their host trees exhibit differences in Td. Our results suggest that close to midday, the presence of lianas does not affect the Td of their host trees; however, lianas tend to have higher values of Td than their hosts across seasons, in both ENSO and non-ENSO years. Although lianas and trees tend to have similar physiological-temperature responses, differences in Td could lead to significant differences in rates of photosynthesis and respiration based temperature response curves. Future models should thus consider differences in leaf temperature between these life forms to achieve robust predictions of productivity.
