One of the most prestigious colleges in the area, Government Post Graduate College Una (H.P.), has a freshly founded department called Department of Environmental Science. The biotic and abiotic components of an environment build it up. Growing consumer demand, greed, and over-exploitation of the environment result in environmental degradation and a loss of the environment’s inherent integrity. The many environmental realms and their ecological functions are harmed by unsustainable industrial growth, uncontrolled infrastructure development, contaminated effluent discharge into water bodies, agricultural runoff containing synthetic chemicals, and deforestation. Our Vedas make clear reference to protecting the environment by maintaining a harmonious relationship between God, Nature, and Man. As an illustration, the RigVeda discusses the five fundamental elements of Earth, Water, Air, Fire, and Space. The foundation of life is made up of these five elements. While Atharva Veda views Earth as the Mother and her creations as her offspring, Yajur Veda offers respect and peace to all aspects of Mother Earth. Our Puranas also discuss the environment and how to conserve it. The Varaha Purana recommends conventional plantation as a path to heaven.
