A record number of over 6000 cities in 117 countries are now monitoring air quality, but the people living in them are still breathing unhealthy levels of fine particulate matter and nitrogen dioxide, with people in low and middle-income countries suffering the highest exposures. https://www.who.int/news/item/04-04-2022-billions-of-people-still-breathe-unhealthy-air-new-who-data

These particles can travel hundreds of kilometres, crossing municipal, state, and even national boundaries. For example, about 30% of air pollution in the Indian state of Punjab comes from neighbouring Pakistan. Further east, an estimated 30% of pollution in Bangladesh’s largest cities originates in India, given the predominant wind direction from the northwest to the southeast. https://blogs.worldbank.org/en/endpovertyinsouthasia/united-south-asia-can-beat-air-pollution
This is what we should be focused on, reducing general pollution and reducing air pollution. Its rather sad that the climate change movement has stolen this focus and made it into a CO2 hysteria. Clean air give good health and save lives.
