Correct answer: A) To define a 'safe operating space' for humanity, beyond which there is an increased risk of large-scale and possibly irreversible environmental change
Explanation
The planetary boundaries framework identifies limits for processes such as climate change, biosphere integrity and freshwater use, within which humanity can operate safely. Crossing these boundaries increases the risk of abrupt or irreversible change. The framework is scientific, not legally enforceable, and the social foundation of minimum needs is a feature of Doughnut Economics rather than of planetary boundaries.
