"The situation is unaesthetic. Human waste is full of disease-causing bacteria contaminating the air, food and water," said Nazeer Watto, an environmental expert who works for the Anjuman Samaji Behbud (Organisation for Social Welfare) in Faisalabad.
"When waste is generated in the open and remains untreated, it interacts with the food chain through the soil, water and crops. The disease causing bacteria are incorporated in the food we consume, persisting longer and having worst effects by the time they reach humans," says Mustafa Talpur of WaterAid. "Sanitation is for human dignity; otherwise it enhances class isolation since only the lowest classes endure it."
