This is excellent. His approach is disarming and he successfully conveys the ridiculousness of the CO2 hysteria. He very aptly tagged on that plants will start to die if our CO2 goes any lower. It's typical that the zealots have no clue the actual percent CO2 in the atmosphere. Being schooled on it won't stop their zealotry though. Too much money and power are behind this. In one ear and out the other.
