Andy Engel has been professionally occupied with climate adaptation and sustainability for years. His knowledge and experience made him realize that change is needed to improve our quality of life. It is better to start with that message early, he says, because ‘children are the adults of the tomorrow’. From that conviction, Andy writes playful children’s books together with Judith Koppens. In this way he wants to show them that children can change something big by doing something small and easy.
