I am well aware of the severity and seriousness of climate change. The actions of fossil fuel companies are crimes against humanity, making them the worst mass murderers ever. We are in the midst of an extinction event — the holocene — that has done irreparable damage to our environment.
So of course, my sarcastic self decided that was a good idea for a t-shirt featuring the six major extinction events and what (or who) caused them. Because sometimes all you can do is laugh.
