Ganges [SEP] Introduction
The Ganga is threatened by severe pollution. This poses a danger not only to humans but also to animals; the Ganga is home to approximately 140 species of fish and 90 species of amphibians. The river also contains reptiles and mammals, including critically endangered species such as the Gharial and South Asian river dolphin. The levels of fecal coliform bacteria from human waste in the river near Varanasi are more than a hundred times the Indian government's official limit. The Ganga Action Plan, an environmental initiative to clean up the river, has been considered a failure which is variously attributed to corruption, a lack of will in the government, poor technical expertise, environmental planning and a lack of support from the native religious authorities.
