Planetary Health
An interdisciplinary framework examining the interconnections between human health and the Earth's natural systems, focusing on how environmental degradation impacts global wellbeing.
Planetary Health
Planetary health is an emerging field that studies the intricate relationships between human health and the state of Earth's natural systems. This concept recognizes that human wellbeing is fundamentally dependent on the stability and resilience of our planet's ecosystem services.
Core Principles
- Interconnectedness
- Human health cannot be separated from environmental health
- Changes in one system inevitably affect others
- Recognition of complex systems approaches
- Multiple Scales
- Local to global impacts
- Immediate and long-term consequences
- Individual and collective responsibilities
Key Challenges
