River pollution happens when harmful substances like garbage,
chemicals, or sewage enter rivers and make the water dirty or unsafe.
This can hurt animals, plants, and people who use the river for
drinking, fishing, or farming.
Common causes:

Factory waste: Factories may dump dirty water with chemicals
into rivers.

Sewage: Untreated waste from homes can end up in rivers.

Farming: Fertilizers and pesticides from farms can wash into
rivers when it rains.

Littering: Plastic and trash thrown in or near rivers pollute the
water.
Effects:

Fish and other animals can die or get sick.

Water becomes unsafe for people.

Dirty rivers can smell bad and look unpleasant.
Simple ways to help:

Don’t throw trash in or near rivers.

Support proper waste treatment.
