An environmental scientist continues his relentless battle to save the Ganga, this time by starting a fast unto death. THE campaign to save the Ganga has cost one life in the hill State of Uttarakhand. The life of another activist now hinges on the government's commitment. In 2011, Swami Nigamananda of Matri Sadan undertook a fast unto death demanding an end to illegal sand mining in the Ganga, at least in Haridwar where the Kumbh Mela, a mass Hindu pilgrimage, takes place. The governments, both in Uttarakhand and at the Centre, paid no heed. The swami died after fasting for 115 days.
