The planetary boundaries model, introduced by Rockström and others in 2009, provides a useful framework for assessing the planet’s health. It identifies nine interconnected factors ...

Six of nine planetary boundaries are currently transgressed. The length of the wedges symbolizes what the current state of the corresponding process is, in relation to the distance from the planetary ...
