Bubonic Plague

Just imagine, right now we're all "polluting" the atmosphere with "pollutants", like sulphur dioxide, nitrogen oxide, carbon monoxide and what-nots. Isn't this just like the time when oxygen was being pumped into the atmosphere by cyanobacteria and plants a long time ago. And in the end many of the species that exist today are all dependant on oxygen, humans, cats, etc and they were all evolved from those that survived the oxygen.

So isn't it great that we're pumping out all these "pollutants"? We're probably creating the infrastructure for eg. sulphur dioxide based life-forms. Aerobic may not even mean anything next time. Just imagine all those new and unimaginable species that could evolve.

Did i get anything about the biology and history wrong? I'm trying to share an interesting thought i had.
