... But the O2 didn’t build up in the atmosphere yet. Where did it go? It dissolved in the oceans and oxidized the iron that was also dissolved in the water and precipitate onto the sea bed. These are the most important iron ores, for us, we get most of our steel from these ores…thanks to photosynthetic ...
