In a general sense, it is art that helps improve our relationship with the natural world. There is no definition set in stone. This living worldwide movement is growing and changing as you read this.
Much environmental art is ephemeral (made to disappear or transform), designed for a particular place (and can't be moved) or involves collaborations between artists and others, such as scientists, educators or community groups (distributed ownership). These variables can make exhibiting this work difficult for traditional museums so we created greenmuseum.org: an online museum for global the environmental art movement.
