The earth is rich in ecology, but many species are on the verge of extinction due to human’s disruption. TRANGER hopes to let children recognize these endangered species and build awareness of conservation via the assembly of and the interaction with the clothes stand. TRANGER presents different endangered species with the small hooks based on the height scale of the stand according to the altitude of the living height of each species, and the graphic on the hooks represent different species. Children are allowed to repeatedly build awareness of conservation during the interaction.
