The science of ecopsychology focuses on the relationship that human beings have with nature. The two primary principles of this science is ecology and psychology.

The term "ecopsychology" was first coined by Theodore Roszak in his 1992 book , The Voice of the Earth. An ecopsychologist actually believes that there is some kind of psychological link between the human brain and the planet. That destruction of ecosystems and other species somehow makes humans less sane.

Ocean psychology is the study of how being near or interacting with the ocean can impact human mental health and well-being. This field examines the therapeutic effects of being in and around the ocean, such as reducing stress, promoting relaxation, and improving mood. Researchers in this area also explore how activities like surfing, swimming, or simply walking along the shore can positively affect psychological states.
