Ah thanks I've been meaning to look into plants, how much you'd need to make an impact. Unfortunately the article doesn't mention numbers, like how much CO2 one human produces in a normal or in a well insulated sealed room, and how much of that plants can scrub, and how much light they need.
Another way to think about this would in terms of calories, if plants where to produce 100% calories / edible sugar or starches, it should somewhat match how much CO2 we output. To grow enough potatoes for your daily calories you need about 250m². You probably need less and that would be for a perfectly sealed room.
I don't know about blood concentration, but if it's fine then presumably it isn't affecting cognitive abilities yet. It might also vary from human to human how well they can oxygenate / expel Co2.
i couldn't find it quickly, but there was a factory foreman or owner in china who did a bunch of research on the best plants to clean his factory air, and put them everywhere... supposedly it worked, but they had to dust the leaves regularly... they had broad leaves though...
in beijing maybe?
i'll look again but it seems doable...
in the article it does say it's output depends on a lot of conditions.
(also i have no idea how reputable that site is)
No worries, I'll have to research this stuff later. My ideal / current dream would be something like all the walls of a house (or catamaran) are about 80cm deep greenhouses with aquaculture crops that produce strawberries or similar supplemental crops.
