The right answer is D.
Ecopsychology is a combination of two words:
*Psychology: Science that studies psychic facts.
*Ecology: The study of the relations of organisms with the surrounding world, that is to say, in a broad sense, the science of the conditions of existence of these organisms.
Ecopsychology, situated at the crossroads of natural sciences and human sciences, integrates all that touches the unitary relation of man with nature, and, in this way, his studies maintain close relations with ecosophical currents, the traditional thoughts and artistic visions that preceded it in this process.
Ecopsychology brings together the sensitivity of therapists, the expertise of environmentalists and the energy ethic of environmental activists.
