There is no planet B. Activists share how we must inform and organize ourselves to save the future. "e;Act as though your house is on fire. Because it is."e; Following Greta Thunberg, millions of young climate activists have been taking to the streets around the globe as part of the Fridays For Future movement. They demand that we "e;unite behind the science,"e; as, for too long, climate scientists have been ringing the alarm bells about rising temperatures, tipping points, and the devastating consequences of extreme weather-but politicians do nothing. So how do you begin to end the climate crisis? Luisa Neubauer and Alexander Repenning begin by telling stories. Neubauer cofounded the youth climate activist group in Germany and has become its most prominent voice. In this book she and Repenning weave in personal accounts of their evolution as climate activists with a thorough analysis of how climate change impacts their generation, and what every one of us can and must do about it. The young and old in the United States and around the world can learn valuable lessons from their European counterparts.
