Network of Change is an American charity based in Meeker, Colorado.
All projects proposed by the group not only have to conform to standards for sustainability, but also must be designed to minimize impacts on culture.
The organization was founded after an American Forest Ranger Kasey Cox embarked upon a volunteer trip to impoverished regions of southern Kenya. After the experience, he resigned from his career and sold his possessions in order to spend more time abroad.
The organization is managed by volunteers from around the world.
