The head of Matri Sadan, Swami Shivanand, has thrown a dare to Chief Minister Harish Rawat to arrange an open discourse involving his chosen scientists and experts on the menace of mining in the holy river Ganga in Haridwar. He asked Rawat to clarify things regarding the present state of mining and alleged nexus between mining mafias and political leaders. The people owed an explanation from the CM in view of many who have died fallen into the craters dug to facilitate illegal mining along the outer part of the given area. Shivanand said Rawat had earlier threatened to disclose names of senior State BJP leaders having nexus with the stone crushers operating in different districts of the State, including Haridwar. He must disclose these names now, he demanded.
