Television personality Avi Lewis has flair, energy and media savvy–characteristics you'd expect from a politician. Not only is the 39-year-old a regular face on the small screen, but he is also a social activist. He and his wife Naomi Klein co-produced The Take, a film that documented the take-over of factories in Argentina by workers who turned them into cooperatives during the economic crisis that gripped the South American country more than four years ago.
