Children, educators and wider society
Ask the children to solve some real-world sustainability problems. Ask them to present (creatively e.g song, poem etc) areas of environment they're passionate about and these can be shared as advertisements, videos, pop-ups, billboards around the world for society to learn and be influenced by children.
