Book excerpt: On the outskirts of the Milky Way, floating slowly through space, there hangs a planet unlike any other. It has oceans, deserts, jungles and mountains. It has life that swims, life that soars and life that swings through the trees. It is a place of dazzling variety and infinite wonder - and it's the only world we've got. Climate change is happening, now. But it's not too late to change the story. Meet the humans, from around the world, who are fighting to save our planet. This is your call to arms. Featuring 25 hopeful stories including Greta Thunberg, David Attenborough, Jane Goodall, Wangari Maathai - as well as lesser-known heroes, such as turtle-protector Len Peters, the guardians of the Amazon rainforest, and the poacher patrollers The Black Mambas. This book will transport you from the poles, to the oceans, to the rainforests, with iconic illustration. These are true stories to make you think, make you cry, make you hope - and these are stories to make us all stand together and protect our home. These stories are the proof that one person's small changes can grow into something big, and powerful, and world-changing. So read on to be inspired, as we take our future in our own hands, and together save Planet Earth - for all the living things that call it their home.
