Did you know that one of the dirtiest rivers is located in Varanasi, India? People in India don't have a good water supply because the water comes straight from the Ganges river. Despite the fact that it goes throughout different filters to fertilize the water it still doesn't change that it comes from a very polluted river. The river is so polluted that tons of human waste is thrown into the water everyday. People don't have a choice they clean their clothes and take baths in the dirty waters.
