The TL;DR is that you're not likely to have enough plants to make a significant difference in terms of CO2/oxygen.
Doesn't mean there's no positive effect, but it's probably not due to oxygen levels.
- hanniabu 7y ago> Photosynthesis converts CO2 to O2, but plants also respire. During respiration they convert sugar and oxygen into CO2 and water. This is the reverse of photosynthesis, and it happens in all cells, all of the time, day and night. Interesting, I wonder how that'll contribute to the snowball effect of global warming since as it gets hotter I'm sure they'll perspire more.
- vkou 7y agoPlants solve prespiration by bringing water from their roots, up to their leaves. They burn sugars for energy they need to live, not for water they need to stay cool. Sugars are difficult to make, water can just be pulled directly from their environment. So, it won't be a noticeable effect.
- im3w1l 7y agoPlants work on a similar principle as human nutrition. CO2 in - CO2 out = weight gain. A growing plant is on average* a net absorber of carbon dioxide. * On average, not constantly. Since they can't do photosynthesis in the dark, they release CO2 at night.
- vageli 7y agoThe sources in that link seem to suggest that the benefits come from removal of CO2 and volatile organic compounds from the environment, versus attributing the benefits to oxygen generation.
