Environmental management deals with the different aspects of environment, its structure, function, its quality and its maintenance including conservation of its living and non -living components. The diversified natural resources on this earth provide the necessities for survival of all forms of life including man. Everything that comes from nature has some utility for man but its utilization is possible based on the availability of appropriate technology.
Resources can be renewed simultaneously along with their exploitation (forests, crops, wildlife, groundwater, wind and solar energy) . They can maintain themselves by natural recycling or can be replenished by proper management. Simultaneously, non-renewable resources cannot be recycled and can get exhausted by unlimited and continous use (mineral ores, coal, petroleum etc). They cannot be replaced easily. This would lead to a situation where non- renewable resources may come to an end after a certain period of time.
Expanding human population resulted in expanding needs of man. With scientific and technological advancement man started utilizing natural resources at a much larger scale. Continuous increase in population caused an increased demand for resources. Therefore, conservation of natural resources makes important contributions to the social and economic development of the country.
