Nature is often overlooked as a healing balm for the emotional hardships in a child's life. You'll likely never see a slick commercial for nature therapy, as you do for the latest antidepressant pharmaceuticals. But parents, educators, and health workers need to know what a useful antidote to emotional and physical stress nature can be. Especially now.

Increasingly the evidence suggests that people benefit so much from contact with nature that land conservation can now be viewed as a public health strategy.

Nature-deficit disorder describes the human costs of alienation from nature, among them: diminished use of the senses, attention difficulties, and higher rates of physical and emotional illnesses. The disorder can be detected in individuals, families, and communities.

Time in nature is not leisure time; it's an essential investment in our chidlren's health (and also, by the way, in our own).

I do not mean to imply that the good old days were perfect. But the institutions and structure--the web--of society needed reform,not demolition. To have cut the institutional and community strands without replacing them with new ones proved to be a form of abuse to one generation and to the next. For so many Americans, the tragedy was not in dreaming that life could be better; the tragedy was that the dreaming ended.

If getting our kids out into nature is a search for perfection, or is one more chore, then the belief in perfection and the chore defeats the joy. It's a good thing to learn more about nature in order to share this knowledge with children; it's even better if the adult and child learn about nature together. And it's a lot more fun.

What happens when all the parts of childhood are soldered down, when the young no longer have the time or space to play in their family's garden, cycle home in the dark with the stars and moon illuminating their route, walk down through the woods to the river, lie on their backs on hot July days in the long grass, or watch cockleburs, lit by morning sun, like bumblees quivering on harp wires? What then?
