On the podcast this week, Our Land’s Laura Paskus sits down for a two-part discussion with Arturo Sandoval, one of the organizers of the first Earth Day in 1970. In the first half of their conversation, Sandoval tells us about his role in putting together the first event and takes a step back to look at how it has since changed. Later, the two talk broadly about the concept of colonization, how it has defined the world around us and observe how it is intertwined within capitalism.
