"Humans exhale about 1 kg of carbon dioxide per day (http://cdiac.esd.ornl.gov/pns/faq.html). The exact amount depends on age, sex, size, and most importantly activity level." from http://www.gcrio.org/doctorgc/index.php/drweblog/C53/ also, "However, human exhalation of carbon dioxide is part of a closed system. There can be no net addition of carbon dioxide to the atmosphere because the amount of carbon dioxide we exhale can?t be greater than the carbon we put into our bodies by eating plants, or eating animals that eat plants. The plants got the carbon from the atmosphere via photosynthesis." I hope this helps. Have a good day.
