Unbelievable. Our atmosphere is about 70% nitrogen. It's an inert gas. And CO2 is plant food. Some greenhouse growers pay money to get CO2 pumped into the grow space to increase production. The byproduct of photosynthesis is the O2 we breathe.
This isn't even "science" stuff. this was basic social studies when I grew up that explained how the water cycle on earth worked, how the air we breathe comes about, etc.

It's what used to be taught in grammar school. I learned this in fourth grade.
