The framework of planetary boundaries is widely applied to encapsulate the idea that human transformation of the planet is in danger of breaching multiple thresholds in planetary function, leading to dangerous consequences for human futures and for wider life on Earth. It has inspired further concepts, including the “doughnut” model of a safe operating space for humanity. However, specific boundaries are difficult to identify and practically action, and some have argued that a such a boundaries framework hinders developing positive narratives for human and planetary flourishing.
