Environment is the source of life. It not only directs but also determines the existence, growth and development of human beings and all their activities. The quality of our social life depends mostly on the quality of the natural environment.
Primitive man was solely dependent for its existence (food, water and shelter, etc.) on the environment around him. From geographical point of view, environment includes the entire range of external influences—both physical and biological—that affects the life and death of an organism.
It is the force of nature in the form of physical, climatic and biotic factors. This spatial aspect of the environment is studied in details by geographers. Sociologists are not directly concerned with the spatial aspect of the environment.
