A branch of site-specific art which emerged in the 1960s, environmental art is concerned with our relationship to the natural world, attempting to find our place (either in harmony or discord) with the environment. Like most site-specific art it is usually ephemeral (either disappearing or transforming a short time after its creation). It is often designed for one particular location and most modern pieces offer a social or political commentary as well. In addition, environmental art involves a collaboration between artists or people in other disciplines (e.g. scientists, educators, and other members of the community.)
A question to consider:
Does the impermanence of this environmental art make it more or less special?
