There are some good points here, and…

If we’re going to spend money improving indoor air quality, why not go whole hog and make buildings green and made of less toxic materials. Or, oooh, move people out of cities and back to the land where they can grow food and interact with soil bacteria that might strengthen their constitution and microbiome and thereby bolster their immune systems.

Of course fortified by clean air. That’d be nice too.
Or we could continue sterilizing ourselves to death, shoot ourselves up with synthetic antibody codes, and diligently wear masks — while the planet burns as we crank up the machines and try to stay “safe.” 🤔

Yes. Indoor air quality matters, and. So does the rest of it.
