What are the main causes of pollution in the ganges?

The main causes of pollution in the Ganges River include industrial discharge, untreated sewage, and religious practices. Many factories along the river release toxic waste directly into the water, while cities contribute large amounts of sewage, with only a fraction being treated. Additionally, religious rituals, such as cremations and the disposal of offerings, introduce further contaminants. Together, these factors significantly degrade water quality and harm aquatic ecosystems.
