Thank you! I’ve had this touched on before but never with quite such a vivid description, and it has changed how I mentally image the whole event. Now I’m picturing these new bacteria doing their thing, pumping out their toxic wastes without a care in the world as all the earth’s buffers just kept eating it up. Then, just like a beaker high school science experiment suddenly changing color in the blink of an eye, the buffers fill up and BAM! the entire atmosphere becomes toxic, and life itself becomes fire.
