I think evolutionary humility is a great thing to be reminded of, thank you Palomides. What's interesting to me is, an organism wouldn't have to out-compete the majority of already existing natural organisms to end the world, it "only" need replace the base of the ocean ecosystem. If a new form of bacteria killed all of the krill and plankton it would surely have grave consequences.
