Without CO2 the earth would not be able to function and would essentially become a cesspool of dead organisms, and bacteria. Without Co2 plant life would die meaning that human life would become extinct. Plant life and human life have a mutualistic bond.
Thanks. What always surprises me is how dumbed down many Americans are with regard to some very basic and natural laws of life. The government schools do not seem to help us at all. I’m old school so much of what I learned was before the schools got so bad and after I grew up. It seems you and I are in agreement about CO2, so let’s keep on helping others understand these same basic laws of life.
