The general meaning of environment is ‘the surroundings about us’. There are three components of environment:
(i) Physical (abiotic) Component-Land, water, air and the related semi-components are included in it.
(ii) Biotic Component-Plants and animals are included in it. Man is an important part of it.
(iii) Energy Component-The sun is the main source of energy on the earth. So, it is also a part of our environment. Besides it, geothermal energy, tidal energy, wind energy etc. are also included in it.
Man is such a living being who gets affected by the environment as well as affects the environment the most. If we see the historical development order of geography, we find that in the beginning, the geographers had considered the environment stronger than man (Determinism). However, the scientific and technical development made man not only stronger but egoist also. Now he began to feel that Nature is under his control and he can give a fillip to development in the way he likes-the limits of development are infinite for man (Possibilism). Keeping this concept in view, man exploited Nature ruthlessly, the bad results of which began to come out immediately. And then, the geographers propounded the hypothesis of Neo-Determinism.
