| Abstract: | An advocate of a unified geography adopts a biosocial, or natural-social, approach to the definition of several concepts in geography, distinguishing the landscape sphere and the geographical environment. The landscape sphere of the earth consists of the sphere of the natural landscape (comprising both untouched and man-altered nature) and the sphere of human activity, or sociosphere, which includes the sphere of the cultural landscape (agrosphere plus technosphere) and mankind itself. The geographical environment includes the natural environment (man-altered nature plus parts of untouched nature), the material results of the labor of past generations and geographical manifestations of the social environment. |
