The most polluted rivers in the world are in Asia. In fact, most of them are in India. The trash in the area accounts for much of the pollution in their rivers. But India is not the only one with polluted rivers. The Mississippi River in the United States is very polluted. The factories along the river are a main cause for its pollution and the river takes the toxins right down the stream to pollute other water ways. The ships in the river also cause pollution. There is a huge polluting river in Italy too. China's Yellow River is loaded with polluting agents. The pollution in rivers is very dangerous. People drink from the water and eat fish from the water too. Even getting in the water causes toxins to sink into the body which causes a world of issues, healthwise.
People and businesses are the main cause of pollution in general and water pollution is no exception. Plastics are a main culprit and it is people who make plastic and people who discard of plastic waste improperly. The pollution in rivers is a mammoth problem and it simply must be stopped. Applying pressure to places like India would be helpful so they would clean the rivers up and put preventative measures of avoiding pollution in place as well.
Some say the most polluted river in the world is the Citarum in Indonesia, but more is known about the Ganges because it is sacred and people go there to bathe and be cleansed of their sin. Some may even drink from it because they have no choice or some Hindus believe it's an elixir.
The Ganges River is the third largest river (by discharge) in the world, it affects the lives of 400 million people who dump their waste, use it for drinking, bathing and cooking, throw corpses into the river, thus giving rise to many water-borne illnesses.
