Next time I would suggest you talk about the difference between household air pollution (HAP) and ambient air pollution (AAP) because AAP does factor in a large component of pollutants derived from thermal generators such as sulfar dioxide, nitogen dioxide and carbon monoxide all of which come from poor air quality standards, lower quality coal and the Chinese burning coal in their homes and factories. Coal provides around 70 percent of our electricity requirements and has almost no impact on our health, it is all in how you use it.
