California has a history of making strong environmental decisions, like switching to unleaded gasoline, which greatly improved air quality. There were complaints back in the 1950s and 1960s, but now 40 million people enjoy cleaner air. Phasing out leaded aviation fuel follows the same idea—helping the industry move forward and keeping people healthy. These changes might be tough at first, but they lead to a cleaner, healthier future for Californians.
