If you could reduce CO-2...which is actually impossible you kill off food.....CO-2 IS Plant FOOD...the CO-2 levels in a green house will make Greta puke...yet the plants grow bigger & bigger....the EXTREME LEFT really wants to KILL 2 / 3 rds of the global population...ask them WHY....CO-2 is inessential** to life on this planet....Trump's new Space Force should blast off Greta  ,Gates & Fauci  and let them find a planet that works for them
