How much carbon dioxide is inhaled and exhaled?

The air around you is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide with respect to volume. The composition of what you exhale has 4-5% CO2. Since we can't count the same CO2 twice we will ignore the inhaled amount, as it is still present in the exhaled figure. So our equation should look like this.

CO2 exhaled = (Volume of breath) x (breaths taken per hour) x (hours per day) x (days per year) x (population of planet) x (percent of breath that is CO2)


Alright, let assign some values to these:

• Volume of Breath = about 500cc
• breaths per hour = 960
• hours per day = 24
• days per year = 365
• population of planet = 6,775,235,741
• percent of breath that is CO2 = 5

co2 exhaled =1.42442556 × 10^18 or 142442556000000cc
OR
142442556000000 Litres
OR
142442556000 cubic metres

But really I suppose that means nothing unless put into perspective. If contained into Olympic sized swimming pools, it would take
56 977 022 to hold it all. Might seem like alot, but really it's not if you consider the size of what it is to be compared to.
