I have come to the same conclusion. The realization comes with lots of fear and anxiety, but also a bit of peace. The earth has gone through many mass extinction events and recovered, so hopefully it will do the same after this. It is interesting that this extinction event is caused in part by a species living on it that can see what is going on, had opportunities to prevent/mitigate it, and chose not to.

Days might actually be better. If they go to work and come back to it rusted all over, they will know it was a malicious action. If they start to see rust the next day and see it slowly progress, it might be hard to trace back to someone.
