The success of Last Child in the Woods inspired the creation of Children & Nature Network co-founded and chaired by the book's author, Richard Louv, to encourage and support the people and organizations working to reconnect children with nature.

Green Hour is an organization that provides information on how to reverse Nature-Deficit Disorder, and encourages parents to let their children explore and reconnect with the outdoors.
