What is the main reason for the increasing pollution of rivers?

Options

  1. AIncrease in number of sewage treatment plants
  2. BIncrease in urbanization
  3. CDirect discharge of untreated sewage into rivers
  4. DIncrease in water-borne diseases

Correct answer

C. Direct discharge of untreated sewage into rivers

Step-by-step solution

Due to increasing urbanisation, sewage is being produced in much larger quantities than ever before. However the number of sewage treatment plants has not increased enough to treat such large quantities. So the untreated sewage is often discharged directly into rivers leading to their pollution and increase in water-borne diseases.
