I was reading about the Great Oxidation event theory in which new bacteria converted CO2 into oxygen and changed the atmosphere. After a while, there was so much oxygen in the atmosphere that they could no longer survive in their own waste. One life form used CO2 to generate oxygen. Billions of years later, another life form (humans) used the abundant oxygen to generate CO2. Maybe this is just how life works. Life just uses up all the resources they find, regardless of what happens in the future. Maybe humans can't stop this even if we're aware because it's just coded in the laws of physics. Entropy?
