Who says CO2 isn't plant food?
Backstory
Memo to Doubters—I was Tempted to say “Deniers”—CO2 is Plant Food!as you can see, CO2 level at present, last batch off growing rice and grain, is stunted compared to that grown at double current CO2 levels. When levels are lower than 200 ppm, crops barely grow. When levels are 70ppm and below, the food crop dies, grasses hardly survive.
and to think idiots want to call this trace gas of 4 parts in 10000 a pollutant, which double the amount of in the atmosphere will only increase crop production.
