Did you know that there was no oxygen in earth’s atmosphere until a couple billion years ago, when some mischievous bacteria started pumping it out all over the place? It was called the oxygen catastrophe, and all that poisonous oxygen gas in the air is thought to have led to the evolution of many new things such as nuclear envelopes and sex. I like to remember it once in a while.

Yeah! It’s crazy; it was one of the bigger mass extinction events. It rusted all of the exposed iron on the planet too, which I think is just cool.
