Not all heroes wear capes, some just a yellow trench! Greta is only the last of a series of eco-heroes who, with their strength and loud voice, brought world's attention to ecological issues to defend nature and the environment. This title presents some of the most important "eco-heroes", both men and women, some of a very young age, who battled for a cleaner world or the safety of animals. From WWF's founder Julian Huxley, to Greenpeace's, from National Geographic explorers Mike Fay and Michale Nichols to Swedish Greta Thunberg: read their stories and what they have accomplished! Great examples for children to follow: everyone who has a voice and strong ideas can become an eco-hero!
