Why is the Ganges Rive so polluted?

Untreated sewage pours into it.

People who can't afford cremation bury their loved ones in it.

Trash is thrown into it.

All of the these choices.

All of these choices are correct. The Ganges River is considered one of the most polluted rivers in the world due to the large amount of untreated sewage, industrial waste, and agricultural runoff that is dumped into it, as well as the practice of the unaffordable cremation, and human and animal remains that are disposed of in the river. Additionally, trash and plastic waste are also thrown into the river, worsening its pollution problem.
