CO2 is used by plants and trees to grow....its called photosynthesis.
That's why growers have tanks of CO2 in greenhouses.
I’m not arguing that. I’m just telling of the USSC decision (law of the land) that CO2 is a pollutant and the EPA has the duty to regulate it. Add pollutants to the list of things they cannot understand. You know, like what a woman is?
Hog processors use CO2 chamber rooms to process hogs. It works very well. They pass out while the heart keeps beating to bleed them out as best as possible. They pass out, get hung up by the back legs, throats cut, and bleed out, while on a conveyor line.
