Raheem tells to his neighbours, "stagnation of sewage in our surroundings is harmful to our health." Do you support this? Why?

Yes, I support Raheem because stagnation of sewage in our surroundings led to growth of many disease-causing microorganisms. Stagnation of sewage provides a favorable environment to the disease-causing microorganisms and they start growing there in large number and act as a great threat to our life.

Also, many other organisms like housefly who keep roaming in our homes sit on that sewage and then on our foods and other things and thus cause different diseases.

So, Raheem is very correct that stagnation of sewage is harmful to our health.
