Quizplus · Accepted Answer

Many parasites release fertilized eggs in the feces of humans and other animals, and if the feces are not disposed of properly or if there is open defecation, these eggs can come into contact with people and animals, leading to the spread of diseases. Toilets provide a safe and hygienic way to dispose of human waste, reducing the transmission of such diseases.
