Overview
The lecture introduced environmental ethics and normative ethical theories, linking them to conservation decisions and moral standing in nature. It outlined instrumental versus intrinsic value and frameworks for deciding what entities deserve moral consideration.
Field Study Context
- Research involves a fish telemetry study in a cold-water sound; crew uses submersion/floater suits.
- About 180 receivers are synced on the seafloor; each fish transmits every five minutes.
- Approximately 150 fish tagged across six to seven species; triangulation by three receivers with depth via pressure sensors.
- Annual May downloads yielded over 400 million data points; large data management challenge.
- Surgeries for radio-tag implantation done on a dedicated boat; bycatch processed onshore.
- Tissue sampling for stable isotopes and fatty acids infers diet, foraging location, and trophic position.
- Example: Large pike (~8 kg) contained nearly a two-pound prey item, likely a sucker or whitefish.
- Focus: Track movements and test attraction or avoidance relative to aquaculture net pens.
Course Logistics
- Two remaining content classes (today and Wednesday); Friday is a review for exam focus.
- Exam is in person; location/date shown in course listing on the university system.
Framing the Big Questions
- What are we trying to protect in conservation, and why?
- Necessity to justify protection arguments to stakeholders (developers, consultants, First Nations, etc.).
- Exploration of legal strategies: species rights and personhood for elements of nature (e.g., a river in Quebec granted personhood).
- Central theme: Identify which entities merit protection and at what level (species, ecosystems, biodiversity).
Moral Patients and Environmental Ethics
- Moral patient: an entity to which we owe direct moral obligations.
- Discussion prompts:
- Humans as moral patients: broad agreement.
- Sentient animals (can feel pleasure/pain): many in favor.
- All animals as individuals (sentient and non-sentient): mixed views.
- Ecosystems and biodiversity as moral patients: debated, more nebulous.
- Need to articulate reasons beyond intuition when advocating protections.
Normative Ethics: Theories and Tools
- Goal: Systematize, defend, and recommend right/wrong behavior with logical grounding.
- Approach: Use simple cases to build general principles, then apply to specifics.
Summary Table of Normative Ethics
| Theory | Core Idea | Decision Basis | Strengths | Criticisms |
|---|
| Utilitarianism (Consequentialism) | Maximize overall welfare for those affected | Consequences; sentience can be quantified | Clear aim to maximize good; scalable in theory | Requires constant, complex calculations; multiple value “currencies”; may conflict with justice and distribution; no room for supererogation |
| Deontology | Act by rules/principles binding in all cases (categorical imperatives) | Universalizable maxims; duties (e.g., do not lie) | Provides firm guidance; avoids case-by-case paralysis | Absolutist; generates trivial duties; bad outcomes possible (e.g., “Nazi at the door”); values only rational beings |
| Virtue Ethics | Emphasize moral character and virtues | Intrinsic goods; cultivate virtues (courage, justice, temperance, etc.) | Balances extremes (“golden mean”); focuses on character | Morality varies by culture; virtues can be displayed by evil agents |
| Social Contract Theory | Agreed rules among self-interested agents to enable civil society | Collective agreement; balance individual rights and greater good | Addresses gaps in other theories; embeds social enforcement | Excludes some entities from moral concern; depends on who is party to the contract |
Case Illustration: Trolley Problem
- Setup: Divert trolley to kill one instead of five.
- Utilitarian: Pull the switch (maximize welfare).
- Deontologist: May refuse if rule prohibits killing or instrumentalizing people.
- Issues: Quantifying welfare; differing value metrics; future consequences; justice concerns.
Environmental Ethics: Values and Standing
- Applies metaethics and normative ethics to duties toward nature and environmental decision-making.
Instrumental (Utilitarian) Value of Nature
- Reasons: Medicines, ecosystem services (e.g., water filtration), mental health, cultural and spiritual benefits.
- Economic framing: Willingness to pay; maximize human benefits.
- Limitations:
- Leaves out entities with no clear human utility (e.g., mosquitoes).
- Places conservation in economic arenas; can be morally uncomfortable.
Intrinsic Value of Nature
- Definition: Valuable as an end in itself, not merely as a means.
- Common assertions:
- Forests and forest species have intrinsic value (e.g., advocacy positions).
- Nature as a whole has intrinsic value.
- Implication: Expands moral patients beyond humans.
What Counts Morally? Positions Compared
- Key question: Which entities possess intrinsic value and deserve moral standing?
Comparative Table of Moral Standing Positions
| Position | Humans | Sentient Animals | Non-sentient Organisms | Species | Habitats/Ecosystems | Notes/Criticisms |
|---|
| Anthropocentrism | Yes | No | No | No | No | Human-only standing; unpopular in environmental ethics |
| Sentientism | Yes | Yes | No | No | No | Excludes non-sentient life and systems |
| Biocentrism | Yes | Yes | Yes | No | No | Individualistic; excludes species/ecosystems as moral patients |
| Holism/Ecocentrism | Yes | Yes | Yes | Yes | Yes | May de-emphasize individuals; called “eco-fascism” by critics |
Conservation Dilemmas and Trade-offs
- Holism criticism: Protecting collectives can override individual welfare.
- Example to be discussed: Protecting caribou species by culling wolves raises moral conflict between species-level goals and individual sentient rights.
Key Terms & Definitions
- Moral patient: Entity owed direct moral consideration.
- Sentience: Capacity to feel pleasure or pain.
- Instrumental value: Value as a means to human ends.
- Intrinsic value: Value as an end in itself.
- Categorical imperative: Absolute, universalizable duty guiding action.
- Supererogation: Actions above and beyond duty (challenging under strict consequentialism).
- Social contract: Agreed framework enabling civil peace and shared rules.
Action Items / Next Steps
- Prepare for two remaining content sessions; Friday dedicated to exam review and focus areas.
- Reflect on personal positions: Which entities you consider moral patients and why.
- Be ready to analyze conservation cases (e.g., wolf culls for caribou) using multiple ethical frameworks.
- Check exam details (time/location) on the university system for this course.
