Planetary Boundaries
Definition
noun
A scientific framework identifying nine Earth system processes that must remain within safe limits to maintain a stable and habitable planet.
Interpretation
The ecological thresholds of life. These are not rules — they are warnings written in data and drought. Crossing them is not freedom — it's forgetfulness. They remind us: Earth has limits, and so must we.
Living Invitation
Learn one planetary boundary today — like freshwater use or biodiversity loss — and reflect on how your daily choices touch it.
