[air quality drops to an all-time low UN headquarters in New York abandons flag raising]-UN Secretary General spokesman Diarik said on June 8 local time that for the first time, the UN headquarters in New York has given up raising the flag because of air pollution. The flags of 193 member States outside United Nations headquarters are usually raised by United Nations security personnel on working days. When New York is faced with torrential rain, strong winds, heavy snow and other extreme weather, it will give up raising the flag. Air pollution is severe on the east coast and parts of the Midwest of the United States due to the spread of wildfires in Canada. Air quality in New York has fallen to an all-time low in the past two days.
