Human geography mainly focuses on the study of ecological adjustment and regional organisation of various regions. In what way does a group of humans living in a region on earth utilises the environment for its biotic, economic, social and cultural development, and what changes does it make in the environment? Study of all these facts is the basis of human geography. It is due to the humans that population, population regions and resources have emerged.
Mankind has changed, transformed and adjusted its activities and lifestyle according to its environment. In this way, we can see that whatever is included in the subject matter of human geography is directly or indirectly associated with human itself. In this subject, study of the mutual relationships of all the complex facts of the human and the environment along with time is done while assuming the human to be the basis. Due to these conditions only, human geography as a subject focuses mainly on humans.
