I'm really excited that there's a growing movement of people and organizations working to reconnect children with nature!
I love i love dirt by Jennifer Ward. And I'm currently reading Richard Louv's Last Child in the Woods—it's a wonderful, comprehensive look at the importance of outdoor play and nature in kids' lives.
The website childrenandnature.org, which provides access to the latest news and research in the field, continues to build on this movement. (A desire to encourage connection with nature, outdoor exploration, and basic physical activity—in a lighthearted way—is a big reason I felt compelled to create i get around.)
