The Invisible Killer will take you on a journey from London to Los Angeles to Beijing, challenging our ideas of what creates air pollution and how we measure it, and introducing us to incredible individuals whose groundbreaking research paved the way to today''s understanding, often at their own detriment. Dr Fuller argues that to change the future of our planet and collective global health, city and national government action is essential. It is not for lack of evidence that air pollution harm persists. Instead it remains in place due to a lack of political will to make changes to our urban lives, to persuade the public and to make polluters bear the full cost of the harm that they do.
