DELHI, INDIA - DECEMBER 14: Litter and debris float down a stretch of the Yamuna river on December 14, 2009 in Delhi, India. In a city of approximately 16 million, over a quarter of New Delhi residents have no access to piped water. City residents pour an estimated 950 million gallons of sewage into the Yamuna River everyday, 50% of which enters untreated. The entire Yamuna River right from its origin to confluence with the river Ganges and its tributaries are subject to human activities, which directly or indirectly affect the water quality. 2.1 million children in India under the age of 5 die each year from water-borne diseases. The World Bank reports India stands on the edge of an era of severe water scarcity as the city's population has grown over 40% in 15 years. Acording to UNICEF, water-borne diseases are responsible for more deaths than AIDS, Malaria and Measles combined. (Photo by Daniel Berehulak/Getty Images)
