This inspiring picture book retells the story of Nobel Peace Prize nominee Greta Thunberg - the Swedish teenager who has led a global movement to raise awareness about the world's climate crisis - using allegory to make this important topic accessible to young children.Greta is a little girl who lives in a beautiful forest threatened by Giants. When the Giants first came to the forest, they chopped down trees to make houses. Then they chopped down more trees and made even bigger homes. The houses grew into towns and the towns grew into cities, until now there is hardly any forest left. Greta knows she has to help the animals who live in the forest, but how? Luckily, Greta has an idea...A section at the back explains that, in reality, the fight against the 'giants' isn't over and explains how you can help Greta in her fight.By buying a copy of this book, you are making a donation of 3% of the cover price to Greenpeace UK.
