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. These upcoming years are crucial as world leaders will agree on a new sustainable development framework for the next 15 years. The proposed 17 Sustainable Development Goals include targets to end poverty, to ensure healthy lives and quality education and to combat climate change, among others. The decisions taken will undoubtedly have a huge impact on children's lives and rights today as well as the lives and rights of future generations.
