Environmental ethics Study Guide

📖 Core Concepts Environmental Ethics – a branch of practical philosophy that argues for protecting natural entities and using resources sustainably. Scope – influences law, sociology, ecotheology, ecological economics, ecology, and geography. Anthropocentrism – humans are the primary moral concern. Physiocentrism / Ecocentrism – all living and non‑living nature has intrinsic value. Theocentrism – environmental value grounded in divine creation. Libertarian Extension – extends civil‑liberty ideas to non‑human beings (deep ecology, animal‑rights “expanding circle”). Ecologic Extension – stresses interdependence; treats ecosystems as wholes (Gaia hypothesis). Conservation Ethics – values nature for its usefulness to present and future humans. Normative Theories – Consequentialism (outcome‑based), Deontology (duty‑based), Virtue Ethics (character‑based). --- 📌 Must Remember Key historical works: Lynn White (1967), Garrett Hardin “Tragedy of the Commons” (1968), Aldo Leopold “Land Ethic” (1949). Anthropocentrism variants: Strong (human dominance) vs. Weak/extended (human perspective, instrumental values). Consequentialism split: Act utilitarianism evaluates each act; Rule utilitarianism follows general rules that maximize welfare. Deontological claim: entities with intrinsic value are ends in themselves → deserve rights (Taylor’s “teleological centres of life”). Virtue ethics vices: greed, intemperance, arrogance (Sandler). Gaia hypothesis – Earth as a self‑regulating, ethically valuable system. --- 🔄 Key Processes Applying Consequentialism to an environmental issue Identify all affected parties (humans, non‑human animals, ecosystems). Estimate outcomes (well‑being vs. suffering, ecological impact). Choose the action that maximizes overall net benefit. Deriving Environmental Rights (Deontological route) List moral principles (e.g., “do not use beings merely as means”). Determine which natural entities qualify as “ends in themselves.” Formulate legal rights based on those principles. Deep‑Ecology Valuation Recognize intrinsic worth of all biotic/abiotic elements. Reject anthropocentric instrumentalization. Promote policies that preserve ecological integrity irrespective of human utility. --- 🔍 Key Comparisons Anthropocentrism vs. Ecocentrism Anthropocentrism: human interests = moral priority. Ecocentrism: all components of nature have moral standing, independent of humans. Act Utilitarianism vs. Rule Utilitarianism Act: evaluate each specific action’s consequences. Rule: adopt rules that, if generally followed, produce the best outcomes. Libertarian Extension vs. Conservation Ethics Libertarian: focus on rights/intrinsic value of non‑humans. Conservation: emphasize instrumental value for human welfare. Strong vs. Weak Anthropocentrism Strong: humans should dominate nature. Weak/Extended: humans are central to understanding but recognize broader instrumental values. --- ⚠️ Common Misunderstandings “Ecocentrism = anti‑human” – false; it merely assigns intrinsic value to nature, not that humans must be excluded. “All deontologists treat nature as having rights” – not all; some (e.g., Plumwood) critique universal‑law formulations for lacking genuine respect. “Consequentialism ignores duties” – it evaluates outcomes, but rule utilitarianism can embed duty‑like constraints. “Deep ecology denies any human use of nature” – it allows sustainable use that doesn’t undermine intrinsic value. --- 🧠 Mental Models / Intuition “Circle of Moral Concern” – imagine expanding concentric circles: first humans, then sentient animals (Singer), then all living/non‑living entities (ecocentrism). “Resource as a Shared Bank” – Hardin’s Tragedy: visualize a communal bank account; each withdrawal harms the whole. “Gaia as a Living Organism” – think of Earth like a body whose systems (climate, cycles) self‑regulate; harming one part affects the whole. --- 🚩 Exceptions & Edge Cases Non‑sentient entities – many frameworks (e.g., Singer’s utilitarianism) treat them instrumentally, while deep ecology grants them intrinsic worth. Cultural/religious contexts – Theocentrism may prioritize divine stewardship over secular intrinsic‑value arguments. Policy trade‑offs – Conservation ethics may accept short‑term ecosystem damage if it secures long‑term human welfare. --- 📍 When to Use Which Policy design → start with Conservation Ethics for pragmatic human‑benefit arguments; layer Ecocentric justifications for stronger protection. Legal advocacy for animal rights → apply Libertarian Extension + Deontological rights language. Climate‑change mitigation debates → use Consequentialist cost‑benefit analysis (net global welfare). Community education → employ Anthropocentric (weak) framing to relate human perspectives, then introduce Ecocentric values. --- 👀 Patterns to Recognize “Instrumental vs. Intrinsic” wording: questions often signal which paradigm to apply. “Tragedy of the Commons” scenarios → look for shared‑resource depletion and need for collective regulation. “Moral Agent vs. Moral Patient” – agents (humans) can act; patients (nature, animals) receive moral consideration. Citation of historical works (White, Hardin, Leopold) → likely a prompt to discuss foundational paradigm. --- 🗂️ Exam Traps Distractor: “Ecocentrism denies any human benefit.” – wrong; it simply does not make human benefit the sole moral basis. Distractor: “All deontologists grant rights to non‑sentient nature.” – incorrect; Plumwood critiques this universalist approach. Distractor: “Rule utilitarianism evaluates each act individually.” – reversed; that’s act utilitarianism. Distractor: “Strong anthropocentrism = weak‑or‑extended anthropocentrism.” – they are opposite ends of the spectrum. Distractor: “Gaia hypothesis is a scientific law.” – it’s a hypothesis with ethical implications, not a proven law. ---
