Biodiversity, conservation biology, and rational choice

Area of Science:

• Environmental philosophy
• Conservation biology
• Decision theory

Background:

• Critically examines Sahotra Sarkar's recent work on biodiversity and decision theory in environmental policy.
• Focuses on the conceptualization of biodiversity and the application of decision theory in environmental decision-making.

Purpose of the Study:

• To analyze Sarkar's emphasis on practical conservation contexts for biodiversity.
• To evaluate the potential for value-free biodiversity metrics.
• To assess the role and limitations of decision theory in integrating science and ethics in environmental policy.

Main Methods:

• Critical discussion of existing literature and philosophical arguments.
• Conceptual analysis of biodiversity metrics and decision theory frameworks.
• Examination of multi-criteria decision rules and their normative foundations.

Main Results:

• Sarkar's focus on conservation practices may limit the conception of biodiversity.
• Biodiversity metrics can potentially be value-free, independent of specific conservation contexts.
• Tension exists between Sarkar's critique of decision theory and its potential for integrating science and ethics.
• Non-axiomatic multi-criteria decision tools may have practical utility despite violating preference transitivity.

Conclusions:

• Biodiversity conceptualization can be broadened beyond specific practical contexts.
• Value-free biodiversity measurement is a plausible goal for scientific inquiry.
• Decision theory's role in environmental policy requires nuanced evaluation, considering both axiomatic and non-axiomatic approaches.
• Further investigation is needed on the contextual application of decision tools that may not adhere to strict normative requirements.
