Question

How much carbon dioxide does the human race pump into the atmosphere year just by breathing

Answer 1

hi

Answer 2

I've heard by every breath human can blow out about 0.5L carbon dioxide, so in total population it's 3.4 billion Liter by every breath, you do the math, not only human, other animals generate CO2 too.

Urh, Chemistry is my worst among science subjects, coz I hate Chemistry teacher.......

Answer 3

I do not know for sure but if you feel guilty plant a couple of trees. If everybody did that the AGW freaks would have nothing to complain about. It is deforestation in the tropics that is creating the appearance of excess Co2 output by people. Religious fanatics never get it right and love to blame others for problems they have created.

Answer 4

I don't know exactly by just breathing but I do know that humans are responsible for about 4-5% of total carbon dioxide and that CO2 only makes up about .054% of the atmosphere.

P.S. Don't quote me on the 4-5% percent part, may not be remembering it right. I am certain however that if it is not 4-5%, then it is lower.

Answer 5

It's important to remember that by breathing, we're not adding any CO2. It was there to begin with, When you inhale, your lungs extract the oxygen out of the air and the rest is exhaled. You can increase the concentration of CO2 by breathing because you're removing oxygen from the air but you can't increase the total content of CO2.

Answer 6

The act of breathing by any animal is part of the normal carbon cycle and is irrelevant in regards to global warming.  The carbon was removed from the atmosphere by plants to make food.  The net gain or loss in the C02 is zero.
