"Humans exhale about 1 kg of carbon dioxide per day
( The exact amount depends on
age, sex, size, and most importantly activity level."



"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.
