Those of us who have lived in frequently dusty desert areas where people with serious respiratory illnesses have been encouraged by their doctor to move to for improved breathing are skeptical of this.
I’m skeptical of it because it’s the WHO, an organization that has shown itself to be lying and leftist.
I live in an area wherethey say has a rather high rate of air pollution, but they also tell me I got lung damage as a result of the Covid & an accompanying stay in the hospital with they said was double pneumonia. So I’m not sure just what goes on here. I do seem to be pretty short-winded.
