California’sEnvironmental Principles & Concepts
Principle I: The continuation and health of individual human lives and of human communities and societies depend on the health of the natural systems that provide essential goods and ecosystem services.
Principle II: The long-term functioning and health of terrestrial, freshwater, coastal, and marine ecosystems are influenced by their relationships with human societies.
Principle III: Natural systems proceed through cycles that humans depend upon, benefit from, and can alter.
Principle IV: The exchange of matter between natural systems and human societies affects the long-term functioning of both.
Principle V: Decisions affecting resources and natural systems are based on a wide range of considerations and decision-making processes.
