    Oxygen is so crazy that once microbiology in the ancient oceans started producing it, all life on earth nearly died. Like very nearly sterilized the earth.

      At high concentrations, its still fucking awful for us. Easy to forget that the atmosphere is still only 21% Oxygen and 78% Nitrogen. Even setting aside the risks of fire and explosion at higher concentrations, this highly reactive substance degrades the nervous and musculature system.

      You wouldn’t want to wander around in a fully oxygenated environment for the same reason you wouldn’t want to drive your car through a lake of gasoline.
