Environmental Issues


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.

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.

Environmental Pollution


  • Pollution is defined as ‘an addition or excessive addition of certain materials to the physical environment (water, air and lands), making it less fit or unfit for life’.

  • A pollutant is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource.
  • They are constituent parts of the pollution process. They are the actual “executing agents” of environmental pollution. They come in gaseous, solid or liquid form.
