This activity is a collaborative task in which students from different countries work together to invent creative stories about sustainability and environmental protection. The goal is to raise awareness about key environmental issues while fostering imagination, teamwork, and multilingual communication. The stories are written in several languages, giving students the chance to improve their language skills and share cultural perspectives. To collect and showcase all the stories in one place, we used BookCreator, a digital tool that allows students to create and publish interactive books. This platform helped us compile their work in an engaging, visual format that can be easily shared with others.
