If we had not had such a large increase in atmospheric CO2 (only a tiny fraction of which came from human activity), we’d be having to use a whole lot more land to produce the same amount or maybe even less of food. And we’re still far, far below CO2 levels required for optimum plant growth.

Earth has shown a slight increase in forested acres every year since the Surveyor satellites were launched (1968).

All that "extra" CO2 is going to good effect. You'd think the Greens would approve of the outcome...
