[Planetary health and mental health].

Abstract

Climate change is the greatest global health threat of the twenty-first century. Greenhouse gas emissions and the resulting rise in average temperatures are directly linked to heatwaves, droughts, water and food shortages, extreme weather events, rising sea levels and migration movements as well as the loss of biodiversity and the alteration and degradation of ecosystems as we know them. Current estimates suggest that societies need to show much greater efforts to ensure that the global average temperature does not rise by more than 1.5 °C by 2029. Not only climate change but also other man-made factors, such as noise, light, particulate matter and plastics are threatening the health of the planet and therefore inevitably human health as well, both physical and mental health. Poorer planetary health also has an impact on human mental health. This article extends the DGPPN 2023 position paper on climate change and mental health to include the concept of planetary health. In particular, the normative dimension of the Canmore Declaration on Planetary Health, the concept of transdisciplinarity and specific calls for action are presented with their relevance to psychiatry, psychotherapy and mental health and the associations are graphically illustrated.
