Answer 1

 The Ganges River is one of the most polluted rivers in the world yet is used by 500 million people for domestic, industrial, and agricultural purposes. Without proper waste management procedures, the waste generated from inhabitants and local industries have been thrown directly into the river, resulting in heavily polluted waters. People are using this contaminated water out of necessity and it is causing many to experience gastrointestinal diseases that can lead to death if untreated. The pollution has caused less dissolved oxygen to be available for aquatic life, resulting in a decrease of some plant and animal species.
