Yes, I did paste the wrong quote. That's what happens when I realize I need to go somewhere and fail to proofread.

Other than that, you should educate yourself about the vast carbon cycle. Carbon in all of its forms, including carbon dioxide, moves between the atmosphere, bodies of water, living things, and even certain minerals. This process has been going on for billions of years.

Here, I will save you the trouble of taking Biology 101, where most scientists get their first real introduction to the carbon cycle:

As I said, there are no exceptions to the fact that all carbon dioxide--the basic building block of *all* life--has come from the atmosphere. And it will return to the atmosphere.

Sorry Mom, but you and that little graphic that you posted are not taking into account the CO2 that is coming out of undersea volcanoes and has never been in the atmosphere. "No exceptions" you said and yet the use of that CO2 by oceanic plant life is an exception. Keep trying though Mom, your fanbase is counting on you!
