Voice of Nature visualises the state of being of a tree by using real time data in order to talk about the urgency of climate change in a way that’s undeniable. The digital art installation Voice of Nature uses real time data that indicates the wellbeing of a tree to warn us about climate change. “Trees and their tree rings are data capsules showing the change in climate happening over the years. Environmental changes and the impact of pollution is indicated by the yearly growth levels shown in the rings. With these accelerating shifts taking place we don’t have time to wait years for this data” says Biersteker. “It’s time to speed up the process to a human pace and show with data what nature is trying to tell us.” Using real time data coming from sensors attached to a tree, the algorithm can generate a tree ring every second. Indicating the tree’s well being and the impact of the environmental changes as they are happening at that moment.
