Remember when they lied to you about SA rainforests being the lungs of the planet? It's not. It's nearly a closed system reuptaking the O2 it makes by day at night and during the day reuptake the CO2 off gassed at night.
Plankton are responsible for the O2 we breath.
Highly speculative and completely irrelevant ot the conversartion, as per usual, petros. If, as the Cap'n alleges, plant growth globally is increasing and human contributions to CO2 in the atmosphere are insignificant, then what is causing CO2 to increase by 1 to 2 ppm per year? If it were a closed system, then tehre would be no effect on CO2. And yet it is increasing.
