The climate movement has lessons for all social impact practitioners working to create a more just and healthy world. While the climate and mental health movements are getting increased attention separately, a small set of leaders working across these movements are prioritizing and integrating mental health and climate advocacy as a unified effort. From climate scientists to psychologists, these actors are creating bi-directional efforts that serve both causes. Importantly, they see these two global crises as inextricably linked, highlighting that people across these movements must integrate these fields of practice rather than working in silos. Beyond prioritizing mental health education and interventions in our initiatives, social impact practitioners across all areas often face personal challenges as we dedicate our time and energy to witnessing and mitigating the world’s inequities. In recent years, particularly in light of the COVID-19 pandemic, many of us have heard repeated calls for self-care in the face of what can be exhausting and painful work.
