A chemical miracle has turned into a global menace The development of PFAS began in the 1940s when manufacturers started producing these chemicals for their unique properties of water, oil, and stain resistance12. Initially celebrated for their versatility in non-stick cookware, firefighting foams, and countless industrial applications, PFAS were considered technological marvels that enhanced modern life13. The strong carbon-fluorine bonds that make these chemicals useful also make them virtually indestructible in natural environments12. ...

The Stark Geography of Energy Poverty Sub-Saharan Africa has emerged as the epicenter of global energy inequity, housing 80% of the world’s electricity-poor population—600 million people living predominantly in rural areas where grid extension remains economically prohibitive12. The region’s 43% electricity access rate masks devastating disparities between urban areas achieving 81% access and rural communities languishing at 34%, a gap that widened during the pandemic as population growth outpaced electrification efforts34. ...

A Planetary Problem with a Social Toll Ocean acidification, driven by anthropogenic carbon dioxide emissions, represents a critical planetary boundary within Kate Raworth’s Doughnut Economics framework, directly linking climate change impacts to marine ecosystem health and human food security. As atmospheric CO₂ levels have risen from pre-industrial concentrations of 280 µatm to current levels exceeding 414 µatm, the ocean’s absorption of this excess carbon has fundamentally altered seawater chemistry1. This process has decreased ocean pH by approximately 0.1 units since the Industrial Revolution, with projections indicating further declines to pH 7.8 by 2100 and potentially as low as 7.45 by 23002. The concept of fish adaptation to ocean acidification sits at the intersection of planetary health and social foundations, as marine fisheries provide essential protein sources for over 3 billion people globally while supporting the livelihoods of millions in coastal communities. ...

Social Capital and Mental Wellbeing in a Sustainable World Social capital represents a critical element within the social foundation of the Doughnut Economics framework that plays a vital role in shaping mental health outcomes. Networks, relationships, trust, and social cohesion that exist within communities have emerged as significant determinants of mental health across various populations and contexts12. The concept encompasses both cognitive elements (perceptions of trust and reciprocity) and structural components (social participation and networks), with each contributing uniquely to mental wellbeing34. ...

Climate’s Deepening Imprint on Global Income and Work The global economy stands at a critical juncture as climate change increasingly disrupts established economic systems and transforms working conditions worldwide. Income and Work represent a key dimension of the social foundation within the Doughnut Economics framework, as climate driven changes reshape labor markets, productivity, and economic output globally. ...
