Make eco-warriors of your little ones at a reading from The Great Big Green Book, filled with ideas about how to look after our planet.
Mary Hoffman and Ros Asquith, author and illustrator of the bestselling Great Big Book series, show the cartoons from the book, which approach a deeply serious subject in an accessible and light-hearted way, and leave plenty of time for questions and discussion.
After the reading, contribute to a Tree of Hope by decorating a paper leaf with your drawn or written feelings about climate change, animals, trees, the ocean, saving energy or creating a happier, more peaceful future.
