Planetary Health: Focusing on the Intersection of Human Health and the Earth System

The core insight of Planetary Health is that the Earth crisis is fueling a global health crisis. Planetary Health examines the links between human health and Earth's natural systems. This review outlines key drivers of environmental degradation and how they lead to global environmental change, which is marked by the transgression of six Planetary Boundaries and causes severe health impacts such as malnutrition and the spread of diseases, with increased risks for vulnerable populations. The concept of Earth system justice highlights the need for just solutions to address inequities within and between generations. The review discusses actions like sustainable food and energy systems, circular economies, governance changes, and collaboration across sectors. It also emphasizes the importance of Indigenous knowledges and building resilience for vulnerable populations. Aligning human well-being with the health of natural systems is necessary to address current challenges and ensure a livable future for all.
