Basically, earth’s atmosphere was devoid of oxygen from its beginning, and it took billions of years to change that. it wasn’t until life had learned about photosynthesis before large amounts of oxygen started to accumulate in the atmosphere.
however, oxygen is a necessary prerequisite for most animal/fungus consumers, as they use oxygen to break down the organic materials. that is probably when major fossil fuel production stopped.
Nothing. You’re just asking trees to do something they’re not meant to do. Absorbing a single year of carbon emissions would require half the planet’s land area of trees. And that’s just while the trees are growing and absorbing a lot of carbon. Trees just aren’t efficient enough on a per acre basis to make a dent in carbon emissions, let alone capturing the carbon already in the atmosphere.
They were for several hundred million years. What changed?
The evolution of micro organisms capable of eating dead trees and emitting CO2 as a metabolic byproduct.
don’t forget the role that the Great Oxidation Event played in this.
