O2 levels since the first thing that breathed them have been steadily on the decline. last i read O2 was like at a 32% concentration. there was a time when it was much much higher (dinosaurs) but since its not stuff keeps getting smaller. i think the bigger question is how do we replace plants with stronger counterparts? we need more primal plants that can scrub the thick layers of CO2. you cant say plants always were scrubbing because the O2 levels have been dropping for as long as we have been measuring them. it took plants millions of year with no air breathing life, just to fill the planet with a moderate amount of O2. if you wanna save the planet stop expelling so much CO2. we exhale far more than a car.
