Fear, sadness, anger: these are just some of the emotions that children most associate with concerns about the future of the planet. 95 % girls and boys surveyed said they were worried about the future of the environment and more than one in 3 (40 %) reported having a bad dream about climate change or a threatened environment and having trouble sleeping or eating because of these thoughts. This follows from the results of a recent Italian study, unique in the international scientific panorama, which was born in the context of the Scuolattiva Onlus educational project "A Scuola di Acqua", carried out nine years ago in collaboration with the Sanpellegrino group and dedicated to raising awareness among the youngest about hydration issues and environmental sustainability.
