'Junior inniclass' is an ecological education program focusing on natural conservation, environmental protection, and resource recycling. Aimed at fostering environmental awareness among children who will lead the future of Jeju Island, we utilize upcycled lipstick crayons and coloring books featuring 12 indigenous plants of Jeju as teaching materials. From 2019 to 2022, 960 elementary students from 31 rural areas in Jeju Island participated, learning to understand Jeju's natural ecology and to live wisely for the sake of the global environment.
