How can we use "humor and storytelling to fend off the apocalypse?" Chip Giller of Grist wants us to get serious. Tracing his own experiences trying to raise awareness about climate change and environmental damage, he realized that people weren't responding to urgent, strident messages about impending doom. (They also could not be motivated to care about faraway wildlife.) "If we want to get people to attend to these things and wake up and act, we need to communicate differently." In 1999, Giller founded Grist. In this talk, he shares his wisdom and challenges us to use humor to highlight complex and crucial issues.
