We’re not the first organisms to alter the atmosphere and cause a mass extinction. The first ones were cyanobacteria and the gas they released was oxygen. They caused
a decrease in the size of the biosphere of >80%
We’re descended from the survivors that adapted to a high-oxygen environment but to this day there are many microorganisms that die if exposed to even small amounts of oxygen.
The great oxidization is what your referring to. It’s pretty impressive. It caused like 90% death to all life, and then life adapted and here we are. It rusted the shit out of the planet too.
