Hmmmmm..
I thought more trees CONSUME more CO2..Oh, well--I'm no scientist.
Thanks for your reply
I apologize- I jumped this one too fast and got it backwards. The speculation is that more CO2 would aid the growth of more forested land. Since the developed nations have moved beyond agricultural systems, much of what was farmland has again been overtaken by natural processes. The forests would grow back at any rate, but scientists have speculated that if there IS an increase of CO2 it would be taken up by plants. Since there are a significant number more of US, it seems like "good engineering" to me.
I'm not a scientist either but since we moved to a rural area, I think the air smells better...
