(i) Construction of such a highway will result in the fragmentation of the habitat and this will disrupt its continuity. The organisms will be confined to smaller area. The fragmentation reduces the amount of functional habitat, the species richness, taxon diversity and may also reduce the ecosystem functioning. Fragmentation also disrupts complex interactions amongst species. It results in annihilation of species and risk of their local extinction and thereby decreased biodiversity. 

(ii) The forests are useful to mankind in many ways. They provide us oxygen and help in bringing rain. They are the source of constructional material, industrial products and products of medicinal importance and also fire wood. They act as the habitat of a wide variety of flora and fauna, and keep the environment healthy. 

(iii) Values exhibited by Kalpna-awareness, love for nature, environmental consciousness, vision to foresee the disaster in the future.
