    What are the main causes of pollution of Indian rivers?

    Answer:

    The main causes of pollution of Indian rivers are: (i) The growing domestic, municipal, industrial and agricultural demand for water from rivers naturally affects the quality of water. (ii) As a result, more and more water is drained out of the rivers, thereby reducing their volume. (iii) A heavy load of untreated sewage and industrial effluents are emptied into the rivers. (iv) This affects not only the quality of water but also the self-cleansing capacity of the river.  (v) The increasing urbanisation and industrialisation has increased the pollution levels of the rivers.
