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 reality of humanity's relationship with the natural world, arriving at philosophically more profound conclusions than those of mainstream environmentalism.
[1] The movement does not subscribe to anthropocentric environmentalism (which is concerned with conservation of the environment only for exploitation by and for human purposes), since deep ecology is grounded in a different set of philosophical assumptions.
Sessions considers the publication of Carson's 1962 seminal book Silent Spring as the beginning of the contemporary deep ecology movement.
They believe that the current materialist paradigm must be replaced - as Næss pointed out, this involves more than merely getting rid of capitalism and the concept of economic growth, or 'progress', that is critically endangering the biosphere.
[10] Deep ecologists believe that the damage to natural systems sustained since the industrial revolution now threatens social collapse and possible extinction of humans, and are striving to bring about the kind of ideological, economic and technological changes Næss mentioned.
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.
It does not claim to be a science, although it 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; this is a common concept always held by primal peoples.
[18] Deep ecologists reject any mechanical or computer model of nature, and see the Earth as a living organism, which should be treated and understood accordingly.
'[20] Arne Næss commented that he was inspired by the work of Spinoza and Gandhi, both of whom based their values on grounds of religious feeling and experience.
[21] Næss criticised the Judeo-Christian tradition, stating the Bible's "arrogance of stewardship consists in the idea of superiority which underlies the thought that we exist to watch over nature like a highly respected middleman between the Creator and Creation".
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: overconsumption in the global north and increasing militarization.
[22] While deep ecologists accept that overconsumption and militarization are major issues, they point out that the impulse to save wilderness is intuitive and has no connection with imperialism.
This claim by Guha and Martínez Alier, in particular, closely resembles statements made, for instance, by Brazilian president Jair Bolsonaro declaring Brazil's right to cut down the Amazon Rainforest.
The inference is clearly that, since European countries have already destroyed their environment, Brazil also has the right to do so: deep ecological values should not apply to them, as they have not yet had their 'turn' at maximum economic growth.
'[24] Næss stated that supporters of the deep ecology movement came from various different religious and spiritual traditions, and were united in this one belief, albeit basing it on various different values.
[30] Deep ecologists point out, however, that "shallow ecology" (resource management conservation) is counter-productive, since it serves mainly to support capitalism, the means through which industrial civilization destroys the biosphere.
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.
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.
[3] Eco-critic Jonathan Bate has called deep ecologists 'utopians', pointing out that 'utopia' actually means 'nowhere' and quoting Rousseau's claim that "the state of nature no longer exists and perhaps never did and probably never will."
... Life in the state of nature, Thomas Hobbes reminded readers of Leviathan in 1650, is solitary, poor, ignorant, brutish and short.
[38] With reference to the degree to which landscapes are natural, Peter Wohlleben draws a temporal line (roughly equivalent to the development of Mumford's 'authoritarian' technics) at the agricultural revolution, about 8000 BC, when "selective farming practices began to change species.
"[39] This is also the time when the landscape began to be intentionally transformed into an ecosystem completely devoted to meeting human needs.
[44][45] At one point Arne Næss also engaged in direct action when he chained himself to rocks in front of Mardalsfossen, a waterfall in a Norwegian fjord, in a successful protest against the building of a dam.
[47] Further, the movement is related to cosmopolitan localism that has been proposed as a structural framework to organize production by prioritising socio-ecological well-being over corporate profits, over-production and excess consumption.
