In this video for the Nature Conservancy, rapper Macklemore explains how municipal green space in his home city of Seattle influenced his career: He and his friends didn’t want to kick it at their parents’ houses, so they went and freestyled in parks. (Side note: Do people really still say “kick it,” or is Macklemore even older than I am?) We knew, of course, that Macklemore was into creative reuse, but who knew he had so many ideas about urban infrastructure? 

The moral here is clear: Want more rappers? Make more parks. It’s just science.
