BharatNotes What is Environmental Ethics?
Environmental ethics is the area of applied philosophy that studies the moral relationship between human beings and the natural world, and asks what value — and what moral standing — belongs to non-human entities such as animals, plants, species and ecosystems. It crystallised as a recognised sub-discipline of philosophy in the early 1970s, when philosophers began to question the long-standing assumption that humans alone are morally considerable. The central debate is whether nature has only instrumental value (useful as a means to human ends) or also intrinsic value (worth in itself, independent of human use).
Key Schools of Thought
Environmental ethics is usually mapped along a spectrum of how widely moral worth is extended.
| Approach | Core idea | Key associated thinker |
|---|---|---|
| Anthropocentrism | Only humans have intrinsic value; nature is valued for human benefit | Traditional Western ethics; "enlightened/prudential" variants |
| Biocentrism | All living things have intrinsic value and moral standing | Paul Taylor; Albert Schweitzer's "reverence for life" |
| Ecocentrism | Value extends to wholes — ecosystems, species, the biotic community | Aldo Leopold (land ethic) |
| Deep ecology | Rejects anthropocentrism; all life has intrinsic worth; calls for an "ecosophy" | Arne Naess |
Aldo Leopold, in A Sand County Almanac (1949), gave ecocentrism its most quoted maxim: "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise." The Norwegian philosopher Arne Naess coined the term deep ecology (and the "shallow vs deep" distinction), arguing for a fundamental shift away from human-centred industrial values.
Global and Indian Dimensions
Environmental ethics is closely tied to the rise of global environmental governance. The 1972 UN Conference on the Human Environment at Stockholm (which led to the creation of UNEP) and the Brundtland Report, Our Common Future (October 1987) translated ethical concern into policy. Brundtland's enduring definition of sustainable development — "development that meets the needs of the present without compromising the ability of future generations to meet their own needs" — encodes the ethical principle of intergenerational equity.
In India, these ideas acquired constitutional form through the 42nd Amendment Act, 1976, which inserted:
- Article 48A (Directive Principle): the State shall endeavour to protect and improve the environment and safeguard forests and wildlife.
- Article 51A(g) (Fundamental Duty): every citizen has the duty to protect and improve the natural environment and to have compassion for living creatures.
Indian thought also contributes its own ethical resources — traditions of ahimsa, sacred groves, and reverence for rivers and forests.
UPSC Angle
For GS4, treat environmental ethics as a toolkit, not a list. Be ready to (i) classify a dilemma as anthropocentric or ecocentric, (ii) apply principles such as intergenerational equity, the precautionary principle and the polluter-pays principle to case studies, and (iii) connect philosophy to Articles 48A and 51A(g). The topic also feeds GS3 (sustainable development, climate change) and Essay themes on development-versus-conservation — making it a high-leverage, cross-paper concept.
