The Ganges River is the most heavily populated river basin in the world. It is also one of the most polluted rivers in the world. Dead carcasses can be seen floating through the river, and methane bubbles can be seen rising to the surface.
Though the Ganges is clearly polluted, it still serves as the most sacred river to Hindus. It is also also a lifeline to millions of Indians who live along its course and depend on it for their daily needs such as: bathing, drinking, washing, etc.
Environmental Plans have been made to clean up the river. Unfortunately, the plans have failed due to Indian traditions and beliefs, lack of support from religious authorities, etc.
