Climate change impacts everyone, but the future belongs to young people. No World Too Big celebrates twelve young activists and three activist groups on front lines of the climate crisis who have planted trees in Uganda, protected water in Canada, reduced school-bus climate footprint in Indonesia, invented alternate power sources in Ohio, and more. Fourteen poems by Vanessa Brantley-Newton, David Bowles, Rajani LaRocca, Renée LaTulippe, Heidi E. Y. Stemple, and others honor activists from all over the world and the United States. Additional text goes into detail about each activist's life and how readers can get involved.
