AI systems have the potential to address ethical issues. Case-based re
asoning systems may be the most promising approach to environmental et
hics. Power issues, considered in applied ethics, are a fundamental fe
ature of issues arising from landscape-level management, and may be st
udied using stakeholder modeling techniques, while rule-based systems
may be appropriate for deontological ethical issues (based on duties o
r obligations). Semantic networks may be used to study and summarize t
he views of individuals in groups. Conflict between individual advanta
ge and the common good can be explored through Game Theory.
