How can overpopulation affect one's health and that of the community?

Overpopulation can affect one's health in the community they're in because....

Food shortage, overcrowding, poor water supply and environmental pollution affect the health of the people, particularly the children.

Poor environmental sanitation is a major cause of diseases such as diarrhea, typhoid and cholera. Dirty insects such as flies and cockroaches contaminate food with disease-causing germs.

Many children who play barefoot in dirty areas and do not wash their hands before eating become infected with worms.

Some respiratory diseases such as tuberculosos, pneumonia and bronchitis are worsened by polluted air.

Communicable diseases can easily be transferred from one person to another in an overpopulated area.

I really hoped this helped (:
