Jona’s voice is imaginative, joyful, and true, representing children’s fears and hopes for future generations, and the Committee on the Rights of the Child fully endorses his call for environmental education programmes. Science plays a key role in a more sustainable world. In this book, a little boy and his brother illustrate how science, when used in a just and honest way, could change the world for the better. With their creativity, commitment, and hopeful visions, the child authors can inspire us all to find the necessary will and resources to cooperate for sustainable solutions.
