2022 marks 150 years since the first modern Arbor Day was celebrated in the state of Nebraska. We are honoring this occasion by looking into the history of Birdsey Northrop, the unsung hero of Arbor Day, who helped popularize the idea both in the US and internationally. And we'll learn about how tree planting holidays are celebrated in different countries around the world. Music is by Academy Garden. Cover Art is by @boomerangbrit on Instagram.
