Our
Planetary Boundaries research identifies that there are also other
processes critical to the functioning of the Earth System that are so impacted by human activities that they, too, demand management at the global level.
The
Planetary Boundaries framework proposes quantitative limits for human perturbation of
critical Earth system
processes, and a «safe operating space» within which human activity should attempt to stay in order to avert the risk of large - scale, possibly abrupt or irreversible environmental change.
