Environmental art can take many forms, but at the core the concept is the juxtaposition of humankind’s relationship with nature. Many artists create their works by using recycled products turning them into aesthetic images; others interact with the forces of nature – wind or water, for example – to reveal something about our world in the process. Others re-envision the delicate balance between humans and our planet, making statements about our role in the stewardship of Mother Earth. A modern day example of the latter is Spencer Tunick’s plans to photograph naked Israelis at the Dead Sea. But it’s an ancient display of art in Iran that is capturing imaginations in a remote area of the country…penises. Everywhere.
