Trees and grass are gonna be pissed!!
“Trees and grass are gonna be pissed!!”
Nah humans couldn’t pull 2000+ billion tonnes of CO2 out of the air which is what it would take to go from 440 to 150 ppm and even then trees grow just fine at 150ppm the planet’s tropics were covered in trees even during the last glacial maximum when CO2 got down under 200ppm grasses evolved during this period they are the literal evolutionary adaptations too low CO2 levels. We eat grasses all of the world’s main staple foods are grasses except potatoes...rice,corn,wheat,barley,rye,sorghum all grasses and all of them evolved as the result of low CO2
