At the edge refers to the boundaries between plants and humans in protected areas (greenhouses, windows) created by humans, whether they are maintained or fallow. Greenhouses and urban gardens represent a space where human beings create good living conditions for vegetation, sometimes recreating the conditions of distant or extinct ecosystems. Through the representation of these spaces, the author wonders about their future development because of global warming. Their confinement is reminiscent of the medical environment and the representations are sometimes blurred, suggesting the glass or the fence that is placed between the visitor and the patient, here nature, which he looks like a spectacle. This configuration can be seen as a metaphor for the hospital room. Mother Nature, sick, will she be healed by those who have contaminated her?
