- Deep ecology
Deep ecology is an environmental philosophy which promotes the inherent worth of all living beings regardless of their instrumental utility to human needs, plus the restructuring of modern human societies in accordance with such ideas. Deep ecology argues that the natural world is a complex of relationships in which the existence of organisms is dependent on the existence of others within ecosystems. It argues that non-vital human interference with or destruction of the natural world poses a threat therefore not only to humans but to all organisms constituting the natural order. Deep ecology's core principle is the belief that the living environment as a whole should be respected and regarded as having certain basic moral and legal rights to live and flourish, independent of its instrumental benefits for human use.

Deep ecology is an environmental philosophy which promotes the inherent worth of all living beings regardless of their instrumental utility to human needs, plus the restructuring of modern human societies in accordance with such ideas. Deep ecology argues that the natural world is a complex of relationships in which the existence of organisms is dependent on the existence of others within ecosystems.
It argues that non-vital human interference with or destruction of the natural world poses a threat therefore not only to humans but to all organisms constituting the natural order.
Deep ecology's core principle is the belief that the living environment as a whole should be respected and regarded as having certain basic moral and legal rights to live and flourish, independent of its instrumental benefits for human use. Deep ecology is often framed in terms of the idea of a much broader sociality; it recognizes diverse communities of life on Earth that are composed not only through biotic factors but also, where applicable, through ethical relations, that is, the valuing of other beings as more than just resources.
It is described as "deep" because it is regarded as looking more deeply into the actual reality of humanity's relationship with the natural world arriving at philosophically more profound conclusions than those of mainstream environmentalism. Deep ecology takes a holistic view of the world human beings live in and seeks to apply to life the understanding that the separate parts of the ecosystem including humans function as a whole. The philosophy addresses core principles of different environmental and green movements and advocates a system of environmental ethics advocating wilderness preservation, non-coercive policies encouraging human population decline , and simple living.
In a essay,  environmentalist George Sessions identified three people active in the s whom he considered foundational to the movement: author and conservationist Rachel Carson , environmentalist David Brower , and biologist Paul R.
Sessions considers the publication of Carson's seminal book Silent Spring as the beginning of the contemporary deep ecology movement.
Other events in the s which have been proposed as foundational to the movement are the formation of Greenpeace , and the images of the Earth floating in space taken by the Apollo astronauts. Deep ecology proposes an embracing of ecological ideas and environmental ethics that is, proposals about how humans should relate to nature. Proponents of deep ecology oppose the narrative that man is separate from nature, is in charge of nature, or is the steward of nature,  or that nature exists as a resource to be freely exploited.
They cite the fact that indigenous peoples under-exploited their environment and retained a sustainable society for thousands of years, as evidence that human societies are not necessarily destructive by nature. They believe a different economic system must replace capitalism , as the commodification of nature by industrial civilization, based on the concept of economic growth, or 'progress', is critically endangering the biosphere.
Deep ecologists believe that the damage to natural systems sustained since the industrial revolution now threatens social collapse and possible extinction of the species.
They are striving to bring about ideological, economic and technological change. Deep ecology claims that ecosystems can absorb damage only within certain parameters, and contends that civilization endangers the biodiversity of the earth. Deep ecologists have suggested that the optimum human population on the earth, without fossil fuels, is 0. Unlike conservation, deep ecology does not advocate the controlled preservation of the landbase, but rather 'non-interference' with natural diversity except for vital needs.
In citing 'humans' as being responsible for excessive environmental destruction, deep ecologists actually refer to 'humans within civilization, especially industrial civilization', accepting the fact that the vast majority of humans who have ever lived did not live in environmentally destructive societies - the excessive damage to the biosphere has been sustained mostly over the past hundred years. In Bill Devall and George Sessions summed up their understanding of the concept of deep ecology with the following eight points: .
Its restriction to humans is … anthropocentrism with detrimental effects upon the life quality of humans themselves The attempt to ignore our dependence and to establish a master-slave role has contributed to the alienation of man from himself. No single species of living being has more of this particular right to live and unfold than any other species". By the early s the above figures put in place the intellectual foundations of deep ecology.
Deep ecology is an eco-philosophy derived from intuitive ethical principles. It does not claim to be a science, but is based generally on the new physics, which, in the early 20th century, undermined the reductionist approach and the notion of objectivity, demonstrating that humans are an integral part of nature - a concept always held by primal peoples. They do not dispute the theory that human cultures can have a benevolent effect on the landbase, only the idea of the control of nature, or human supremacy, which is the central pillar of the industrial paradigm.
The tenets of deep ecology state that humans have no right to interfere with natural diversity except for vital needs: the distinction between vital and other needs cannot be drawn precisely. In Richard Kahn promoted the movement of ecopedagogy , proposing using radical environmental activism as an educational principle to teach students to support "earth democracy" which promotes the rights of animals, plants, fungi, algae and bacteria.
The biologist Dr Stephan Harding has developed the concept of 'holistic science', based on principles of ecology and deep ecology. In contrast with materialist, reductionist science, holistic science studies natural systems as a living whole. The emphasis on action is important. This is what makes deep ecology a movement as much as a philosophy. Guha and Martinez-Allier critique the four defining characteristics of deep ecology.
First, because deep ecologists believe that environmental movements must shift from an anthropocentric to an ecocentric approach, they fail to recognize the two most fundamental ecological crises facing the world today, 1 overconsumption in the global north and 2 increasing militarization. Second, deep ecology's emphasis on wilderness provides impetus for the imperialist yearning of the West. Third, deep ecology appropriates Eastern traditions, characterizes Eastern spiritual beliefs as monolithic, and denies agency to Eastern peoples.
And fourth, because deep ecology equates environmental protection with wilderness preservation its radical elements are confined within the American wilderness preservationist movement. An example of such exploitation is the ongoing deforestation of the Amazon in Brazil under President Jair Bolsonaro. Animal rights activists state that for an entity to require intrinsic rights, it must have interests.
For example, a single-celled bacteria might move towards a certain chemical stimulation, although such movement might be rationally explained, a deep ecologist might say that this was all invalid because according to his better understanding of the situation that the intention formulated by this particular bacteria was informed by its deep desire to succeed in life. One criticism of this belief is that the interests that a deep ecologist attributes to non-human organisms such as survival, reproduction, growth, and prosperity are really human interests.
Deep ecologists counter this criticism by the assertion that intelligence is not specific to humans, but a property of the totality of the universe of which humans are a manifestation. Grey believes that developing a non-anthropocentric set of values is "a hopeless quest". He seeks an improved "shallow" view. The eco-centric view thus only becomes 'hopeless' within the structures and ideology of civilization. Outside it, however, a non-anthropocentric world view has characterised most 'primal' cultures since time immemorial, and, in fact, obtained in many indigenous groups until the industrial revolution and after.
As such, the eco-centric narrative is in not alien to humans, and may be seen as the normative ethos in human evolution. Social ecologist Murray Bookchin interpreted deep ecology as being misanthropic , due in part to the characterization of humanity by David Foreman of Earth First!
Bookchin mentions that some, like Foreman, defend misanthropic measures such as organising the rapid genocide of most of humanity. In response, deep ecologists have argued that Foreman's statement clashes with the core narrative of deep ecology, the first tenet of which stresses the intrinsic value of both nonhuman and human life.
Arne Naess suggested a slow decrease in human population over an extended period, not genocide. He suggests that deep ecologists fail to recognise the potential for human beings to solve environmental issues. In response, Deep Ecologists have argued that industrial civilization, with its class hierarchy, is the sole source of the ecological crisis. Daniel Botkin concludes that although deep ecology challenges the assumptions of western philosophy, and should be taken seriously, it derives from a misunderstanding of scientific information and conclusions based on this misunderstanding, which are in turn used as justification for its ideology.
It begins with an ideology and is political and social in focus. They also cite the work of environmentalists and activists such as Rachel Carson , Aldo Leopold , John Livingston , and others as being influential, and are occasionally critical of the way the science of ecology has been misused. This intuitive observation is born out by the current perilous environmental situation.
Peter Singer critiques anthropocentrism and advocates for animals to be given rights. However, Singer has disagreed with deep ecology's belief in the intrinsic value of nature separate from questions of suffering.

Scavengers are animals that consume dead organisms that have died from causes other than predation. Decomposers and detritivores complete this process, by consuming the remains left by scavengers. Scavengers aid in overcoming fluctuations of food resources in the environment. Obligate scavenging is rare among vertebrates, due to the difficulty of finding enough carrion without expending too much energy. Well-known invertebrate scavengers of animal material include burying beetles and blowflies , which are obligate scavengers, and yellowjackets. Fly larvae are also common scavengers for organic materials at the bottom of freshwater bodies.

Соши замолчала. - Полезный груз? - предложил Бринкерхофф. - Количество жертв. Ущерб в долларах. - Нам нужна точная цифра, - напомнила Сьюзан. - Оценки ущерба всюду приводятся разные.
Тот, конечно, был мастером своего дела, но наемник остается наемником. Можно ли ему доверять. А не заберет ли он ключ. Фонтейну нужно было какое-то прикрытие - на всякий случай, - и он принял необходимые меры. ГЛАВА 113 - Ни в коем случае! - крикнул мужчина с короткой стрижкой, глядя в камеру. - У нас приказ.
Я протестую… - У нас вирус, сэр.
Говорила Мидж - излагая серию необычайных событий, которые заставили их нарушить неприкосновенность кабинета. - Вирус? - холодно переспросил директор. - Вы оба думаете, что в нашем компьютере вирус. Бринкерхофф растерянно заморгал. - Да, сэр, - сказала Мидж.
Тогда он дал бы нам ключ, чтобы мы могли уничтожить вирус. Сьюзан стало абсолютно очевидно, что план Танкадо ужасным образом рухнул. Он не собирался умирать.
- Я спущусь вниз, в подсобное помещение, и выключу рубильник. Стратмор медленно повернулся.
Сьюзан не слышала ни единого слова. - Останься со мной, - увещевал ее голос. - Я залечу твои раны. Она безуспешно пыталась высвободиться.
Ты должен это сделать! - потребовала она и, отвернувшись, начала что-то печатать на клавиатуре Большого Брата. - Мне нужен список очередности работы на ТРАНСТЕКСТЕ. Если Стратмор обошел фильтры вручную, данный факт будет отражен в распечатке.
