18 Facts About Planetary boundaries

Planetary boundaries is a concept highlighting human-caused perturbations of Earth systems making them relevant in a way not accommodated by the environmental boundaries separating the three ages within the Holocene epoch.

In 2009, according to Rockstrom and others, two Planetary boundaries were already crossed, while others were in imminent danger of being crossed.

Basic idea of the Planetary Boundaries framework is that maintaining the observed resilience of the Earth system in the Holocene is a precondition for humanity's pursuit of long-term social and economic development.

In 2009, two Planetary boundaries were already crossed, while others were in imminent danger of being crossed.

The Planetary boundaries were "rough, first estimates only, surrounded by large uncertainties and knowledge gaps" which interact in complex ways that are not yet well understood.
