In this special episode, Gill and our new host Kelsey use Earth Day as an opportunity to reflect on humans' long history with the environment, how that has changed, where we are now in the "Anthropocene", and where we might get to in the future.

They also chat about fun facts surrounding material culture. What our ancestors might have used instead of plastic bags, or if you are worried about running out of toilet paper, don't fret! Kelsey and Gill talk about what our ancestors might have used instead.
