“How CO2 Starvation & Plate Tectonics Caused the Greatest Mass Extinction, the Permian Great Dying”

The gradual sequestering of CO2 over millions of years gradually dropped CO2 to starvation levels that reduced photosynthesis, causing the “phytoplankton blackout” and Carboniferous Rainforest Collapse, wide spread ecosystem disruptions and a series of sequential minor extinctions resulting in “Dead Clades Walking” that culminated in end Permian extinctions.
