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.

Some kids don't want to be organized all the time. They want to let their imaginations run; they want to see where a stream of water takes them.

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.

From 1997 to 2003, there was a decline of 50 percent in the proportion of children nine to twelve who spent time in such outside activities as hiking, walking, fishing, beach play, and gardening, according to a study by Sandra Hofferth at the University of Maryland.

The future will belong to the nature-smart-those individuals, families, businesses, and political leaders who develop a deeper understanding of the transformative power of the natural world and who balance the virtual with the real. The more high-tech we become, the more nature we need.

To take nature and natural play away from children may be tantamount to withholding oxygen.

Use all of your senses.
