ROLPA, Feb 22: Locals have expressed deep concern over the likely operation of cement factories around the Mahabharata mountain range, arguing that "this will certainly have an irreparable environmental impact". In view of the ongoing environmental impact assessment by Samrat Cement Private Limited, they have taken to the street. They have warned of consequences if the factory is allowed to excavate the mountains, basically the Murrule highland. The highland situated at an altitude of 2,153 meters near Holeri is considered precious from both environmental and cultural points of view.
