Planetary Boundaries: 'Let the environment guide our development'

First introduced in 2009, this framework identifies and quantifies nine planetary boundaries (or thresholds) which regulate the stability and resilience of the earth. Crossing these boundaries may generate abrupt and irreversible environmental changes that threaten the earth’s capacity to support human life. Tipping points have already been reached for climate change, biodiversity, land-system change, and the nitrogen cycle. In this TED talk, Johan Rockstrom from the Stockholm Resilience Centre introduces the framework, explores how human growth has strained resources, and explains how the global community can prioritize and scale solutions.
