Starvation is not equivalent to death, it means that plants are not growing as fast nor as well as they would with higher levels of CO2. This is a proven fact and has been amply demonstrated in scientific experiments; it is related to well-understood biological processes in photosynthesis. It is the reason greenhouses deliberately increase CO2 ppm. [1] And yes, the plant kingdom has evolved just a few pathways for photosynthesis that worked well at much higher CO2 levels (10-15x current) when they originated; and these pathways are not magically "evolving" to function with diminishing CO2 levels, they've merely become suboptimal given the atmospheric conditions in the last million years, and would stop working below specific levels. Your ignorant dismissals are moronic denials of facts and science. Surely you don't pretend that there is no lower limit to the viable amount of CO2 in the air for Earth vegetation to survive?
