How exactly does “air pollution” kill ? I mean how did they determine air pollution to be the cause of their death ? It’s like saying ‘killed by Climate Change’.
Perhaps as with Covid-19, if they exhibit symptoms of such and came in contact with a documented case... Which could include smokers, which is said to result in "480,000 deaths per year in the United States, including more than 41,000 deaths resulting from secondhand smoke exposure. This is about one in five deaths annually, or 1,300 deaths every day." (https://www.cdc.gov/tobacco/data_statistics/fact_sheets/fast_facts/index.htm),
