For the last half-century, artists and designers all over the world have sought to express the urgency of environmental issues in graphic terms—and to spark action. Their efforts have met with tragically little success, but the variety and ingenuity of their appeals is astounding. Tim Medland, curator of the current exhibition at Poster House in New York, We Tried to Warn You!, joins Clark curator of contemporary projects, Robert Wiesenberger, for an introduction to the exhibition and a conversation about what it might take to get the message across.
