Another British study discovered that average eight-year-olds were better able to identify characters from the Japanese card trading game Pokemon than native species in the community where they lived: Pikachu, Metapod, and Wigglytuff were names more familiar to them than otter, beetle, and oak tree.

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.

An indoor (or backseat) childhood does reduce some dangers to children; but other risks are heightened, including risks to physical and psychological health, risk to children's concept and perception of community, risk to self-confidence and the ability to discern true danger

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).

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.

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.
