The Ganges River begins high in the Himalayan Mountains and flows 1600 miles through India and Bangladesh to the Bay of Bengal. This river provides water and transportation for the over 400 million people who live in its river valley. It is known as Mother Ganges. In spite of the rivers importance and its place in the spiritual lives of Indians, the quality of the water has become poor. Chemicals used in fertilizer and industry are washed into the river every day. Human and animal waste also foul the river. The bodies of dead animals as well as the cremated remains of human beings (bodies that are burned after death and whose ashes are scattered in the river) regularly float down the river. In spite of this, many Indians bathe in the Ganges. They also use the water for drinking and cooking.
