The tree, an important element in biodiversity, is placed in relation to paper consumption in the artwork. Augmented reality is used to create virtual linden trees (Tilia cordata) and paper stacks. The paper stacks show the relationship of the tree as a producer of raw materials. For the global climate, the consumption of wood – for a daily product like paper – plays an important role, because every 5th tree is felled just for paper. In Germany, 55 kg of graphic paper, such as copy paper, is consumed per person and per year. The 12 virtual trees are therefore only enough for the annual needs of about 60 persons. With AR, paper trees visualises the connection between nature's resources and our own consumption in a new way. paper trees | Eva-Maria Lopez in cooperation with Maija Demitere and ASTE.gallery 3D-Art: Līga Vēliņa Technical realisation: Patrick Borgeat Web version: Rogier Jupijn Translations: Ulrike Streubel App: ART+ Funded within the framework of the project funding programme for media art of the UNESCO City of Media Arts Karlsruhe 2022.
