Biocentrism (from Greek βίος bios, "life" and κέντρον kentron, "center"), in a political and ecological sense, as well as literally, is an ethical point of view that extends inherent value to all living things. It is an understanding of how the earth works, particularly as it relates to its biosphere or biodiversity. It stands in contrast to anthropocentrism, which centers on the value of humans. The related ecocentrism extends inherent value to the whole of nature.
Biocentrism does not imply the idea of equality among the animal kingdom, for no such notion can be observed in nature. Biocentric thought is nature-based, not human-based.
Advocates of biocentrism often promote the preservation of biodiversity, animal rights, and environmental protection. The term has also been employed by advocates of "left biocentrism", which combines deep ecology with an "anti-industrial and anti-capitalist" position (according to David Orton et al.).
The term biocentrism encompasses all environmental ethics that "extend the status of moral object from human beings to all living things in nature". Biocentric ethics calls for a rethinking of the relationship between humans and nature. It states that nature does not exist simply to be used or consumed by humans, but that humans are simply one species amongst many, and that because we are part of an ecosystem, any actions which negatively affect the living systems of which we are a part adversely affect us as well, whether or not we maintain a biocentric worldview. Biocentrists observe that all species have inherent value, and that humans are not "superior" to other species in a moral or ethical sense.
The four main pillars of a biocentric outlook are:
Humans and all other species are members of Earth's community.
All species are part of a system of interdependence.
All living organisms pursue their own "good" in their own ways.
Human beings are not inherently superior to other living things.
Relationship between animal ethics and environmental ethics
Biocentrism views individual species as parts of the living biosphere.
