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.

Passion is lifted from the earth itself by the muddy hands of the young; it travels along grass-stained sleeves to the heart. If we are going to save environmentalism and the environment, we must also save an endangered indicator species: the child in nature.

Stress reduction, greater physical health, a deeper sense of spirit, more creativity, a sense of play, even a safer life-these are the rewards that await a family then it invites more nature into children's lives.

This seems clear enough: When truly present in nature, we do use all our senses at the same time, which is the optimum state of learning.

Prize the natural spaces and shorelines most of all, because once they're gone, with rare exceptions they're gone forever. In our bones we need the natural curves of hills, the scent of chapparal, the whisper of pines, the possibility of wildness. We require these patches of nature for our mental health and our spiritual resilience.

In every bio-region, one of the most urgent tasks is to rebuild the community of naturalists - so radically depleted in recent years, as young people have spent less time in nature, and higher education has placed less value on such disciplines as zoology……The times are right for the return of the amateur, twenty-first-century, citizen naturalist. To be a citizen naturalist is to take personal action, to both protect and participate in nature.

The future will belong to the nature-smart.
