The National Conservation Strategy report has documented how solid and liquid excreta are the major source of water pollution and cause of widespread waterborne diseases as only half of the urban residents have access to sanitation; the remaining urban excreta are deposited on roadsides, into waterways, or incorporated into solid waste. Additionally, only three major sewage treatment plants exist in the country; two of them operate intermittently. Much of the untreated sewage goes into irrigation systems, where the wastewater is reused, and into streams and rivers, which become sewage carriers consequently, the vegetables grown from such wastewater, has serious bacteriological contamination. Gastroenteritis, widely considered in medical circles to be the leading cause of death in Pakistan, is transmitted through waterborne pollutants.

Air pollution has also become a major problem as there is no controls on vehicular emissions, which account for 90 percent of pollutants. The National Conservation Strategy Report claims that the average Pakistani vehicle emits twenty-five times as much carbon monoxide, twenty times as many hydrocarbons, and more than three and one-half times as much nitrous oxide in grams per kilometer as the average vehicle in the United States. Government should take measures to reduce all kinds of pollution from Pakistan as it is effecting our environment.
