The role of carbon is much more involved than simple oxygen regeneration. Plants pull carbon dioxide out of the air and convert it into fats, sugars, and proteins. Every other living organism depends on those fats, sugars, and proteins to survive.
Carbon dioxide literally is the stuff of life. No CO2, no life.
Yes I know
nothing can survive without those plants converting that co2
It’s 7th grade science
and the sad part is people don’t know it .
