Dear MEL Topic Readers,
The world’s 100 worst polluted cities are in Asia — and 83 of them are
in just one country
Air pollution has a significant impact on our lives. Millions of people
die each year from air pollution-related health issues. According to the Swiss
air quality company IQAir, over 90% of cities analyzed worldwide didn’t meet
WHO’s air quality standards. Outdoor air pollution is caused by combustion
processes from motor vehicles, solid fuel burning, and industry. Another major source
of air pollution especially in Southeast and South Asia is seasonal
agricultural burning by farmers to remove crop residues left in the field after
harvesting grains. Also, more wildfires have been occurring because of global
warming and polluting air quality significantly especially in North America. In
addition, cooking and heating with unclean fuel, such as firewood, charcoal,
grasses, and animal dung create indoor pollution, which is no less harmful than
outdoor air pollution. Which cities and countries have worse air pollution than
others?
