Air pollution represents one of the most significant environmental health risks globally, with wide-ranging impacts across the human lifespan. Evidence from numerous scientific studies confirms that exposure to air pollutants—particularly fine particulate matter ($PM_{2.5}$), nitrogen dioxide ($NO_2$), and ozone ($O_3$)—is associated with increased morbidity and mortality from respiratory diseases, cardiovascular conditions, adverse birth outcomes, and cognitive impairments1. Even short-term exposure to pollutant levels below many regulatory standards can cause measurable health effects. Current research indicates that air pollution is responsible for approximately 8.1 million deaths annually worldwide, making it one of the leading causes of preventable deaths1. Within the Doughnut Economics framework, air pollution represents a critical planetary boundary that, when exceeded, directly undermines the social foundation of human health. The ecological ceiling breach creates a complex challenge requiring integrated policy approaches addressing both environmental protection and health equity to create a safe and just space for humanity. ...

A (Grim) History of Hollowing Out Our Home The understanding of biodiversity as a planetary boundary has developed considerably over recent decades. Scientists have progressively recognized that biological diversity represents not merely an environmental concern but a fundamental limit to human activities. This recognition began with the Stockholm Resilience Centre’s introduction of the planetary boundaries framework, which identified biodiversity (or biosphere integrity) as one of nine critical Earth system processes that maintain planetary stability1. ...

Past Struggles and Current Gaps The journey toward inclusive civic participation shows a significant evolution from limited representation to broader engagement. Initiatives like the Making All Voices Count program (2013-2017) marked milestones by fostering innovative ways to promote accountable governance, born from an understanding that historical power imbalances excluded many voices12. This historical progression involves ongoing struggles against entrenched power, gradually expanding the concept of who deserves representation, though practice often lags behind ideals. The Brookings Institution frames this within a long historical arc toward full democratic participation, suggesting expanded civic engagement is key to addressing inequities and realizing democracy’s promise34. ...

Introduction: Land Conversion in the Doughnut Land conversion involves both the legal and physical alteration of land from one category to another, carrying significant implications for social well-being and environmental sustainability12. This process typically necessitates regulatory approval, particularly when agricultural land is repurposed for residential, commercial, or industrial uses12. Within the Doughnut Economics framework, land conversion serves as a crucial factor that can either foster sustainable development or drive societies beyond ecological boundaries, contingent upon its management34. ...

From Absence of War to Foundations of Wellbeing The concept of peace within global frameworks has evolved significantly over decades. Initially narrowly defined as the “absence of war” in traditional UN approaches, peace has progressively expanded to encompass positive attributes of social harmony, justice, and human security12. The Brundtland Report in 1987 marked a pivotal expansion, integrating conflict prevention as a key sustainability consideration. ...
