Around 2.5 billion years ago, cyanobacteria caused the Oxygen Catastrophe (https://en.wikipedia.org/wiki/Great_Oxygenation_Event https://en.wikipedia.org/wiki/Great_Oxygenation_Event) and is generally regarded to have killed off nearly all life, as well as triggering the Huronian glaciation lasting some 300 million years. We are not unique in our ability to overwhelm ecosystems. It's true that as intelligent life we should be far, far more aware of our actions.

> We are not unique in our ability to overwhelm ecosystems. We are not unique in that respect, but we are unique magnitude and consistency, we aren't an "event" like others, we are an adaptive species.

  The cyanobacteria literally terraformed thr planet so that it's habitable animal life. If only we could do the same!
