What if oxygen is poisonous and it just takes 75-100 years to kill us?

My science teacher said he thinks that’s true actually

Yeah this is actually pretty much exactly what is going on. It’s why anti-oxidants are such a big deal. Bonus fact: oxygen oxidizes stuff in your cells or, in other words, it’s not toxic, just setting you on fire very very slowly.

More or less accurate in terms of how thick the oxygen levels are. We’re actually 20x(prolly much more than this because of accuracy changes and measurements annually) thinner in Oxygen levels than it was when there were dinosaurs. And it continues to get thinner and filled more with NOx,SOx,Carbon Monoxide, Acids and whatever the hell else smog has(fumes and shit). :’D
