And check out the Eden Project: www.edenproject.com (amazing environmental art and the largest greenhouses in the world) in a giant clay pit in Cornwall, England.
You don't have to go far to find amazing environmental art; just see Peter Vaernet give a tour of the art that was installed in his neighborhood park (CLICK HERE).
