Natural resources can be the basis for building community.
An accepted definition of a community is a group of people who reside in a specific locality and share government, cultural, and historical background. I would add that the natural resources of an area are also shared as a community. The loss of community is of concern to many. People naturally appreciate clean water, fresh air, productive land, scenic vistas, and just being a part of the natural world. And the local watershed is the place to start building community.
