i thought we needed to be closer to 800- 1000 pom for this to be a significant problem but that might have been me confusing studies on cognition with this ?

it would be nice if it sent us sterile.

600ppm is the place where it start affecting human cognition from what i recall. there was a dude in the reddit back in the day called MrVisible that was obsessed with this and had a whole sub about it . i thing it was called r/doomsdaycult or something like that.

EDIT: i just went to find that old sub and reddit banned it of course . maybe a reddit archive will have it.
