The Holocene extinction, or Anthropocene extinction, is the ongoing extinction event caused by humans during the Holocene epoch. These extinctions span numerous families of plants and animals, including mammals, birds, reptiles, amphibians, fish, and invertebrates, and affecting not just terrestrial species but also large sectors of marine life. With widespread degradation of biodiversity hotspots, such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, which goes unrecorded. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background extinction rates and is increasing. During the past 100–200 years, biodiversity loss and species extinction have accelerated, to the point that most conservation biologists now believe that human activity has either produced a period of mass extinction, or is on the cusp of doing so. As such, after the "Big Five" mass extinctions, the Holocene extinction event has also been referred to as the sixth mass extinction or sixth extinction; given the recent recognition of the Capitanian mass extinction, the term seventh mass extinction has also been proposed for the Holocene extinction event.
Kim Stanley Robinson is an American writer of science fiction. He has published 22 novels and numerous short stories and is best known for his Mars trilogy. His work has been translated into 24 languages. Many of his novels and stories have ecological, cultural, and political themes and feature scientists as heroes. Robinson has won numerous awards, including the Hugo Award for Best Novel, the Nebula Award for Best Novel and the World Fantasy Award. The Atlantic has called Robinson's work "the gold standard of realistic, and highly literary, science-fiction writing." According to an article in The New Yorker, Robinson is "generally acknowledged as one of the greatest living science-fiction writers."
Utopian and dystopian fiction are subgenres of science fiction that explore social and political structures. Utopian fiction portrays a setting that agrees with the author's ethos, having various attributes of another reality intended to appeal to readers. Dystopian fiction offers the opposite: the portrayal of a setting that completely disagrees with the author's ethos. Some novels combine both genres, often as a metaphor for the different directions humanity can take depending on its choices, ending up with one of two possible futures. Both utopias and dystopias are commonly found in science fiction and other types of speculative fiction.
In linguistics, a neologism is any relatively recent and isolated term, word, or phrase that nevertheless has achieved popular or institutional recognition, and is becoming accepted into mainstream language. Most definitively, a word can be considered a neologism once it is published in a dictionary.
The Anthropocene ( ) is a proposed geological epoch dating from the commencement of significant human impact on Earth until now. It affects Earth's geology, landscape, limnology, ecosystems and climate. The effects of human activities on Earth can be seen for example in biodiversity loss and climate change. Various start dates for the Anthropocene have been proposed, ranging from the beginning of the Neolithic Revolution, to as recently as the 1960s as a starting date.
Colonization or settlement of Mars is the theoretical migration of humans to Mars and the establishment of long-term human presence on the planet. The prospect has garnered interest from public space agencies and private corporations and has been extensively explored in science fiction writing, film, and art. Organizations have proposed plans for a human mission to Mars, the first step towards any colonization effort, but thus far no person has set foot on the planet, and there have been no return missions. However, landers and rovers have successfully explored the planetary surface and delivered information about conditions on the ground.
Global change in broad sense refers to planetary-scale changes in the Earth system. It is most commonly used to encompass the variety of changes connected to the rapid increase in human activities which started around mid-20th century, i.e., the Great Acceleration. While the concept stems from research on the climate change, it is used to adopt a more holistic view of the observed changes. Global change refers to the changes of the Earth system, treated in its entirety with interacting physicochemical and biological components as well as the impact human societies have on the components and vice versa. Therefore, the changes are studied through means of Earth system science.
The exploration of politics in science fiction is arguably older than the identification of the genre. One of the earliest works of modern science fiction, H. G. Wells’ The Time Machine, is an extrapolation of the class structure of the United Kingdom of his time, an extreme form of social Darwinism; during tens of thousands of years, human beings have evolved into two different species based on their social class.
Naomi Oreskes is an American historian of science. She became Professor of the History of Science and Affiliated Professor of Earth and Planetary Sciences at Harvard University in 2013, after 15 years as Professor of History and Science Studies at the University of California, San Diego.
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution during history. The term is equivalent to the concept of indigenous or autochthonous species. A wild organism is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species.
References to climate change in popular culture have existed since the late 20th century and increased in the 21st century. Climate change, its impacts, and related human-environment interactions have been featured in nonfiction books and documentaries, but also literature, film, music, television shows and video games.
Glenn A. Albrecht, born in 1953, was Professor of Sustainability at Murdoch University in Western Australia until his retirement in 2014. He is an honorary fellow in the School of Geosciences of the University of Sydney.
Degrowth or post-growth economics is an academic and social movement critical of the concept of growth in gross domestic product as a measure of human and economic development. Degrowth theory is based on ideas and research from a multitude of disciplines such as economics, economic anthropology, ecological economics, environmental sciences and development studies. It argues that the unitary focus of modern capitalism on growth, in terms of monetary value of aggregate goods and services, causes widespread ecological damage and is not necessary for the further increase of human living standards. Degrowth theory has been met with both academic acclaim and considerable criticism.
Planetary boundaries are a framework to describe limits to the impacts of human activities on the Earth system. Beyond these limits, the environment may not be able to self-regulate anymore. This would mean the Earth system would leave the period of stability of the Holocene, in which human society developed. The framework is based on scientific evidence that human actions, especially those of industrialized societies since the Industrial Revolution, have become the main driver of global environmental change. According to the framework, "transgressing one or more planetary boundaries may be deleterious or even catastrophic due to the risk of crossing thresholds that will trigger non-linear, abrupt environmental change within continental-scale to planetary-scale systems."
Ecomodernism is an environmental philosophy which argues that technological development can protect nature and improve human wellbeing through eco-economic decoupling, i.e., by separating economic growth from environmental impacts.
Erle Christopher Ellis is an American environmental scientist. Ellis's work investigates the causes and consequences of long-term ecological changes caused by humans at local to global scales, including those related to the Anthropocene. As of 2015 he is a professor of Geography and Environmental Systems at the University of Maryland, Baltimore County where he directs the Laboratory for Anthroecology.
Solarpunk is a literary and artistic movement that envisions and works toward actualizing a sustainable future interconnected with nature and community. The "solar" represents solar energy as a renewable energy source and an optimistic vision of the future that rejects climate doomerism, while the "punk" refers to the countercultural, post-capitalist, and decolonial enthusiasm for creating such a future.
The term collapsology is a neologism used to designate the transdisciplinary study of the risks of collapse of industrial civilization. It is concerned with the general collapse of societies induced by climate change, as well as "scarcity of resources, vast extinctions, and natural disasters." Although the concept of civilizational or societal collapse had already existed for many years, collapsology focuses its attention on contemporary, industrial, and globalized societies.
Criticism of space exploration ranges from simple opposition to the cost and perceived benefit of manned space flight to philosophical or political critique.
