A recent study showed that the River Ganga will not flow cleaner in the near future. Which of the following reasons is FALSE?

The claim that climatic change is why the Ganga will not soon flow cleaner is the false reason among those listed.

A thinning flow rate genuinely worsens cleanliness because less water cannot dilute the pollution load.

Failure of sewage treatment plants is a real cause, as untreated waste then enters the river directly.

Rising volumes of sewage from growing towns are a real and major pressure on the river's cleanliness.

Climate change is a broad long term driver, not the direct immediate reason the river stays polluted.

The core problem remains inadequate treatment of the huge sewage load discharged into the river.
