Why do commercial greenhouses have CO2 generators? I am not following your argument at all. I haven't seen evidence for your first claim (and asked you a follow-up question related to that). We're not cutting down flora for meat farming. We are changing some environments over to farming, but that farm land is largely being used to raise...more plants. In addition, I remember seeing a study (I don't have time to try and find it) that showed that we have more trees now than anytime in the last 500 years. Your third claim (flora also don't grow that rapidly) is just an assertion that doesn't really make sense to me. And the final statement about fossil fuels is a non sequitur.
