Ecovillages (or eco-villages) are communities with a strong ecological focus. An ecovillage might be urban, suburban, or rural and they can range in size from a few to hundreds. Some eco villages are attempts to shift existing neighborhoods or towns toward more sustaainable living and more of a sense of community. Others are newly built, often featuring green or natural building techniques. Ecovillages vary a lot in their degree of community connection and their ecological focus.
