We spend most our time indoors with often 800 ppm… if you’re lucky. I’m a bit annoyed that they don’t specify “the limit of the accepted healthy range” in the summary and didn’t find it with a quick glance over the PDF. But surely there are already people doing over 1000 ppm constantly (ie people that have some outdoors phobia and suboptimal ventilation).

Curious if we are already seeing effects because of this in significantly reduced calcium and phosphorous levels, or if any reduction is largely dietary. Conversely, can you really use calcium and phosphorous levels as a proxy if they are driven significantly by dietary changes?

Well, it is not as if we did not get any warnings, but the rich are getting richer, that is all the US Gov. cares about since 1980. God forbid they and us take a hit on their lifestyle by stop using fossil fuels.
This story could give a hint of what to expect in the far future. Replace Nitrogen with CO2 and you may see what people could be in for :(
