There are these things called "plants"...

From my armchair-research, there are scale challenges with plants.

Algae is commonly the go-to for CO2 scrubbing for it's relative efficiencies. Algae might scrub 1-3 grams of CO2 per liter per day (https://www.osti.gov/servlets/purl/1485133).

Humans exhale approximately 1kg CO2 per day.

I consider 300-1000 L of algae scrubber tanks per person a lot of volume.

The study you linked did not measure CO2.
