Is it true tree farms pump CO2 into the air to help the trees grow faster?

I saw this on Facebook. A conservative friend of mine was bitching about liberals wanting to make laws regarding CO2 that harms business. He doesn’t believe CO2 emissions cause climate change.

This Q is not about whether climate change is real or whether CO2 affects climate change.

I tried to google information on tree farms using CO2 and I didn’t find anything. I have a hard time believing it myself, but thought I would ask the collective.
