About the Book: Produced with the University of Cambridge, this updated collection tells the stories of 22 real-world ‘Earth Heroes’-from Greta Thunberg and David Attenborough to lesser-known figures like Yin Yuzhen and Isatou Ceesay-who have taken meaningful action against climate change. Each inspiring profile demonstrates that individual people, regardless of scale, can make a genuine difference in protecting the planet. Designed as a gift for aspiring climate activists, the book offers hope and concrete examples of grassroots and high-profile environmental action from around the globe.
