Environmental psychology is a branch of psychology that explores the relationship between humans and the external world. It examines the way in which the natural- and our built environments shape us as individuals. Environmental psychology investigates how humans change the environment and how the environment influences humans' experiences and behaviors. The field defines the term environment broadly, encompassing natural environments, social settings, built environments, learning environments, and informational environments. Another important research area within environmental psychology is the study of humans’ influences on the environment, that is, psychological factors influencing pro-environmental behavior and different ways it can be possible to encourage environmentally friendly behaviors, in order to mitigate climate change and biodiversity loss.
According to an article on APA Psychnet, environmental psychology is when a person thinks to a plan, travels to a certain place, and follows through with the plan throughout their behavior.
