Not long ago, I watched the movie Tomorrowland. Sitting in front of me was a group of pre-teen girls, eating popcorn and giggling. At the end of the movie, these girls cheered and clapped with triumphant enthusiasm. The movie (starring George Clooney and Britt Robertson) explores the question of whether the planet can be saved from what ails it (violence, environmental destruction, wars, etc.). After much mayhem, a search ensues for the earth’s dreamers. Dreamers are needed because they haven’t given up. “They’re the future.”
