It's not as simple as more CO2 = better plant growth. In fact it is likely the opposite for C3 plants. [0] Things like Corn, which uses C4 photosynthesis will hardly be affected by more CO2 in the atmosphere. I could go on and on, but this thread is the wrong place for this discussion.

It looks like doubling CO2 causes increase in carbs and a decrease in proteins but the difference is only 1.5-14% depending on the plant species, with soy beans being the least affected. Still, a doubling of CO2 can cause certain tree species overall mass to increase by 138%. If the yields and plant mass overall increase by more than 14%, then perhaps the trade-off is worth it. And this is perhaps why commercial greenhouse growers pump CO2 into them up to 1200PPM. At any rate it does seem like an interesting question. What sort of species will thrive in a high CO2 environment? I do have faith in plants and their ability to adapt to such conditions, as it was the conditions they thrived under in the Mesozoic and beyond. At any rate, thank you for the interesting studies. https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2486.2007.01511.x https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2486... https://academic.oup.com/treephys/article-abstract/14/7-8-9/707/1727792 https://academic.oup.com/treephys/article-abstract/14/7-8-9/...
