The best place to start is with Henry David Thoreau, and DB Johnson's perfect storybooks, Henry Hikes to Fitchburg, Henry Builds a Cabin, Henry Works, and Henry Climbs a Mountain.
We built a Lincoln log cabin...but it really needed a pond beside it.
Henry David Thoreau, A Neighbor to Nature, by Catherine Reef, is an excellent biography. Perfect for young readers.
I suggest it is worth making a spot in your heart for Thoreau.
He speaks to the idealistic, earnest aspirations of 19th century American philosophy, literature, spirituality, environmentalism, and civil justice.
We are not a perfect people. Henry suggests we have the means to become better.
