Everything we eat can be traced back to photosynthesis, the process by which plants take up carbon dioxide from the air and use it to produce the vast array of organic compounds needed for life. (mcgill.ca)
Because every atom of carbon in the exhaled carbon dioxide comes from food that was recently produced by photosynthesis. (mcgill.ca)
So, since all the carbon dioxide we exhale originated in carbon dioxide captured by plants during photosynthesis, we are not disturbing the carbon dioxide content of the atmosphere by breathing. (mcgill.ca)
On the other hand, when we burn fossil fuels such as gasoline, we are releasing carbon dioxide that forms from carbon atoms that had been removed from the atmosphere millions and millions of years ago by photosynthesis and had then been sequestered in the coal, petroleum and natural gas that forms when plants and animals die and decay.
