INDIA - India’s environmental watchdog has concluded that a spiritual festival held in the country last March caused more than $6 million worth of damage to the Yamuna River that could take a decade to fix. An expert panel, established in 2010, was appointed by India’s National Green Tribunal to investigate. The group concluded in its report released Wednesday, that the Art of the Living Foundation’s World Cultural festival held last year had destroyed the bed of the Yamuna river – considered sacred by Hindus – and adversely affected 170 hectares of surrounding floodplains. The massive event, which featured yoga sessions, performances and prayers was attended by some 3.5 million people and left the area “completely destroyed, not simply damaged” the Hindustan Times cited the report as saying.
