Technique: “Frottage” on trees with blue iron oxide. On the left fabric I burned small parts creating holes that formed with the action of fire, I then sewed silkscreen prints of the lifelines of my hands with an ink made from clay gray, thus mixing with the marks of the tree. By these traces of the trees which appear in blue, I refer to the “aerial rivers”, formed thanks to the evaporation of the water of the trees, which capture the humidity of the Amazonian forest and distribute it in a large part of the America, protecting the land from erosion and nourishing the waterways. Human gray marks reflect our relationship with nature, sometimes harmonious but often conflicting in the Anthropocene era in which we find ourselves. The work deals with the sensitive epidermis of the living.
