In this volume, the authors consider how environmental changes affect our social, cultural and political lives and, in doing so, have a direct influence on individuals' health. In contrast to previous research in the area, da Cal Seixas and de Moraes Hoefel emphasize both physical health and mental health as measures of human suffering, in an approach informed by the concept of subjectivity. Ultimately, the authors argue that contemporary environmental changes have a significant effect on the mental and physical wellbeing of the world's population, and that analysis and proposals for action should address both concerns in an effort to improve our quality of life.
