Ouch ... that didn't hurt me.
the oceans phytoplankton obtains its co2 from the oceans not from the atmosphere.
so by cutting down trees you are adding more co2 into the
ppm of the air that we breath because the trees cant convert
the co2 into oxygen after its been cut down and buried.
so that is as serious as I think it is.
here's an article I found.

https://en.wikipedia.org/wiki/Oxygen#Photosynthesis_and_respirationVariations of Oxygen shaped the climates of the past. When oxygen declined, atmospheric density dropped and this in turn increased surface evaporation, and led to precipitation increases and warmer temperatures
sounds a lot like what's happening today doesn't it.
