Save Ganga Movement is a widespread Gandhian non-violent movement supported by saints and popular social activists across the Indian States Uttar Pradesh and Bihar in support of a free Ganga. The movement is supported by Ganga Seva Abhiyanam, Pune-based National Women's Organisation (NWO) besides those of many other like-minded organisations and with the moral support from many religious leaders, spiritual and political, scientists, environmentalists, writers and social activists. Ganga Calling – Save Ganga is another such campaign supported by Indian Council for Enviro-Legal Action (ICELA). Causes Ganges is the largest and the most sacred river of India with enormous spiritual, cultural, and physical influence. It provides water to about 40% of India's population in 11 states. It is estimated that the livelihoods of over 500 million people in India are dependent upon the river, and that one-third of India's population lives within the Ganges Basin. Despite this magnitude of influence and control by the river over present and future of the country, it is allegedly under direct threat from various man made and natural environmental issues. Pollution River Ganges flows through the most densely populated regions of India passing 29 cities with population over 100,000, 23 cities with population between 50,000 and 100,000, and about 48 towns. A sizeable proportion of the effluents in Ganges are caused by this population through domestic usage like bathing, laundry and public defecation. Countless tanneries, chemical plants, textile mills, distilleries, slaughterhouses, and hospitals contribute to the pollution of the Gangas by dumping untreated toxic and non-biodegradable waste into it. It is this sheer volume of pollutants released into the river every day that are causing irreparable damage to the ecosystem and contributing to significant sanitation issues. Dams Built in 1854 during the British colonisation of India, the Haridwar dam has led to decay of the Ganges by greatly diminishing the flow of the river. The Farakka Barrage was built originally to divert fresh water into the Bhagirathi River but has since caused an increase of salinity in the Ganges, having a damaging effect on the ground water and soil along the river. Apart from this, Bangladesh and India faced major tensions due to this barrage. The government of India planned about 300 dams on the Ganges in the near future and the tributaries despite a government-commissioned green panel report that has recommended scrapping 34 of the dams citing environmental concerns.
