Bad Outdoor Air Kills Millions Every Year
In 2016, an estimated 4.2 million premature deaths were caused by poor outdoor air quality. According to the World Health Organization (WHO), about 91 percent of the premature deaths were people from low- and middle-income countries. The highest rates of air pollution deaths are in Southeast Asia and the Western Pacific regions.
However, the remaining 9 percent were from higher-income countries, like the United States and the United Kingdom (UK). This shows that even affluent nations can have air quality issues that lead to deaths.
