GS Paper 4 (Ethics)Environmental ethics

What is meant by environmental ethics? Why is it important to study? Discuss any one environmental issue from the viewpoint of environmental ethics.

Based on 26 evaluated answers to this question on CollectorBabu: here is what aspirants most often missed, the mistakes that cost marks, and a model answer.

What most aspirants missed

  • Define environmental ethics as the study of the moral relationship between humans and nature, with duties toward the environment, and name anthropocentrism, biocentrism and ecocentrism in one or two lines
  • Explain intergenerational equity as the core ethical principle, linking it to the Brundtland Report definition of sustainable development
  • Use the intrinsic vs instrumental value distinction to explain why nature's worth is debated
  • Apply the chosen issue to an explicit ethical dilemma, such as Vedanta-Niyamgiri tribal rights or the Narmada Bachao Andolan, showing competing values
  • Cite key thinkers such as Aldo Leopold's land ethic or Arne Naess's deep ecology to show theoretical depth
  • Include one concrete ethical policy tool such as the polluter pays principle, the precautionary principle or common but differentiated responsibilities

Common mistakes

  • Defining environmental ethics vaguely as 'respecting nature' or 'eco-sensitive handling' without naming any ethical framework
  • Listing importance points that overlap, such as intergenerational equity and moral responsibility, without a concrete example
  • Describing an environmental issue factually (deforestation, temperature rise, pollution) without stating the ethical viewpoint or dilemma
  • Using generic examples or unverifiable references instead of specific case studies, reports or laws
  • Ending with a weak conclusion that merely repeats the introduction instead of stating a clear ethical position

What the better answers did

  • Clear one-line definition followed by named frameworks such as anthropocentrism versus ecocentrism
  • Ethical analysis of the chosen issue presented from two or three contrasting viewpoints, each stated in a sentence
  • Concrete references such as the Brundtland Report, the polluter pays principle, CBDR, or a named Indian case
  • A balanced way forward that reconciles development with ecological limits instead of treating them as opposed

Introduction

Open by defining environmental ethics as the moral relationship between humans and nature, and name the anthropocentric and ecocentric positions in one line so the rest of the answer has a framework.

Conclusion

Close by stating your own ethical position on the chosen issue, grounded in intergenerational equity, rather than repeating the points.

Model answer

Environmental ethics is the branch of philosophy that examines the moral relationship between humans and nature, and the duties humans owe to the environment and to future generations. It asks not only what we can do to nature, but what we ought to do. Its core debate is between anthropocentrism, which values nature only for human benefit, biocentrism, which grants moral worth to all living beings, and ecocentrism, which values whole ecosystems and their intrinsic worth. The distinction between intrinsic value (value in itself) and instrumental value (value for human use) lies at the centre of this debate.

Why it is important to study

  • Intergenerational equity: The Brundtland Report (1987) defined sustainable development as meeting present needs without compromising future generations' ability to meet theirs. Ethics makes this a binding duty, not a choice.
  • Resolving resource conflicts: Ethical principles such as the polluter pays principle and the precautionary principle guide decisions where science is uncertain, as in the Supreme Court's use of these principles in the Vellore Citizens Welfare Forum case (1996).
  • Climate justice: Common but differentiated responsibilities, recognised under the UNFCCC and the Paris Agreement, reflect the ethical claim that historically high emitters must bear a greater burden.
  • Policy direction: Ethical reasoning supports shifts such as Green GDP and the sustainable lifestyle emphasis in India's national missions.

Issue: Depletion of Sand and River Ecosystems

Unregulated sand mining in rivers, such as the Chambal and Yamuna, degrades aquatic habitats, lowers groundwater, and endangers bridges and farmers' livelihoods.

  • Anthropocentric view: Sand is a construction input; mining is justified for housing and jobs, provided it is taxed and licensed. The ethical question is only whether human welfare is maximised now.
  • Ecocentric view: The river and its aquatic life have intrinsic value. Mining that destroys the riverbed violates the integrity of the ecosystem and demands restraint even at economic cost.
  • Intergenerational view: Sand formed over centuries cannot be renewed in a human lifetime. Present extraction shifts costs onto future generations who will inherit dry rivers and collapsed fisheries.
  • Indian ethical lens: Gandhi's maxim that the earth provides enough for everyone's need, not everyone's greed, challenges unlimited extraction. Sacred groves and river worship traditions reflect the same restraint.

The ethical resolution combines the precautionary principle, strict enforcement of the Sustainable Sand Mining Management Guidelines, and community participation, balancing livelihoods against ecological limits.

Way forward

  • Adopt an ecosystem-based management approach
  • Use Environmental Impact Assessment with mandatory ethical and intergenerational review
  • Strengthen community stewardship and local governance

Environmental ethics moves the debate from what is profitable to what is right. Grounding decisions in intergenerational equity and in the recognition that nature has value beyond human use is essential for sustainable development.
