Environmental Art!

WHAT IS ENVIRONMENTAL ART?
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).
