Today's children are living a childhood of firsts. They are the first daycare generation; the first truly multicultural generation; the first generation to grow up in the electronic bubble, the environment defined by computers and new forms of television; the first post-sexual revolution generation; the first generation for which nature is more abstraction than reality; the first generation to grow up in new kinds of dispersed, deconcentrated cities, not quite urban, rural, or suburban.

All spiritual life begins with a sense of wonder, and nature is a window into that wonder.

We have such a brief opportunity to pass on to our children our love for this Earth, and to tell our stories. These are the moments when the world is made whole. In my children's memories, the adventures we've had together in nature will always exist.

The times I spent with my children in nature are among my most meaningful memories-and I hope theirs.

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).

Leave part of the yard rough. Don't manicure everything. Small children in particular love to turn over rocks and find bugs, and give them some space to do that. Take your child fishing. Take your child on hikes.

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.
