Ecopsychology is a field which studies the relationship between the physical surroundings and human behavior. It is also known as environmental psychology, green therapy, psychoecology, transpersonal ecology, Gaia psychology, and depth psychology. This science focuses on how people can have more sustainable lifestyles while strengthening their connection with nature. It also seeks to identify why humans continually harm the environment. Ecopsychology believes that emotional wellbeing and social connections can be positively influenced by having a deep connection with nature. For instance, individuals who walked in nature had lower levels of rumination as compared to those who walked in more urbanized ambience.
