You would need absurd numbers of plants. You breathe out ~11L/hr CO2, which is ~22g. Over a day this is ~0.5 kg. So your plants would need to be getting collectively 0.5kg heavier daily by pulling CO2 from the air just to balance out your own breathing, let alone the CO2 coming in from the outside.
- rufus_foreman 4y agoWhat's the math if I have a cat?
- jefftk 4y agoMaybe the cat weighs 5% of what you do, and respirates 5% as much as well? In which case it's within the margin of error of the above.
- rufus_foreman 4y agoI'm from the midwest. The cat weighs like half a percent of what I do.
- jefftk 4y agoA really small housecat weighs 5lb. For that to be 0.5% of your weight you'd need to be half a ton, at which point my math above is a bit low.
- rufus_foreman 4y agoAll right so do the math. Have you ever been to the midwest?
- jefftk 4y agoYes, several times, touring with my (niche) band. But I acknowledge that "people who go to contra dances" is not a uniform sampling of the population.
