CO2: It’s Got What Plants Crave

[Giggling Ghast]

Or, to put it another way, too much of a good thing is bad. We need water to live, but can die of water poisoning if we drink too much.

I know that logically, but I wanted to make sure there wasn’t anything up-to-date and scientific I should be citing.

I just came across someone who insisted “forests breath CO2; ever hear of photosynthesis!!!!” So this is a common belief among a certain crowd, apparently.
