Our house is on fire: Greta Thunberg's call to save the planet. Greta Thunberg's call to action is powerful. While written like a kids book, this book is for the adults who aren't listening about climate change and don't want to understand that they need to act now in order to put out the house fire. (This book may contain a sharpie mark on the top or bottom edge and may show mild signs of shelfwear.)
