Air pollution is responsible for millions of deaths each year. Air pollution - the combination of outdoor and indoor particulate matter, and ozone - is a risk factor for many of the leading causes of death including heart disease, stroke, lower respiratory infections, lung cancer, diabetes and chronic obstructive pulmonary disease (COPD). Air pollution has been linked to higher rates of cancer, heart disease, stroke, and respiratory diseases such as asthma. In the U.S. nearly 134 million people—over 40 percent of the population. The WHO puts air pollution on a par with smoking and unhealthy eating. It is urging its 194 member states to cut emissions and take action on climate change, ahead of the COP26 summit in November. Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include.
