50 years ago, the oxygen level on earth was 30%, today, it's 18%, on a good day excluding smog/pollution/general farts.

It's 21%, and this fact is 100% false. Such a drastic change in the oxygen levels on the planet would likely kill off millions of species, ourselves included.

Consider these facts, from this page:

-Oxygen deficient atmosphere. When the oxygen content is below 19.5 percent, it is too low to provide enough oxygen for a working person.

-Oxygen enriched atmosphere. Oxygen content above 23.5 percent causes combustible substances to burn more vigorously than in normal atmosphere. For instance, in an oxygen enriched atmosphere, a person's hair, clothing, and even skin will burn rapidly if ignited.

21% depending on the area FTL. Downtown TO I am likely still high on 18%. And while I may be off on 50 years, this change HAS occured in our atmosphere, I just pulled that number out of my ass.

I haven't been quick with this info in a long time now.
