Men started using and modifying environment as early as evolution of human civilization. But gradually with the advent of industrial revolution, modifying the environment turned into manipulation and misuse resulting in large scale environmental destruction and degradation. Degradation takes place when earth’s natural resources are depleted.
The environmental degradation can be defined as the condition wherein the socio-economic, technological and institutional activities of mankind results in the deterioration and depletion of natural resources like air, water, soil, wildlife, forest etc. In this process habitats are lost, bio diversity is destroyed, and species become endangered or extinct and survival becomes difficult.
