F or Adah Crandall , a high-school student in Portland, Oregon, a daily annoyance is family members asking when she is going to learn to drive. Ms Crandall, who is 16, has spent a quarter of her life arguing against the car-centric planning of her city. At 12 she attended a school next to a major road down which thousands of lorries thundered every day. When a teacher invited a speaker to talk about air pollution, she and her classmates were galvanised. Within a year, she was travelling to Salem, Oregon’s capital, to demand lawmakers pass stricter laws on diesel engines.
