One of our biggest fears nowadays is that our kids might some day get lost in a “sea of technology” rather than experiencing the natural world. TV and computer games are leading to a serious disconnect between kids and the great outdoors, which will change the wild places of the world, its creatures and human health for the worse, unless adults get working on child’s play.

Without having a nature experience, kids, can turn out just fine, but they are missing out a huge enrichment of their lives. That contributes to everything from their physical health and mental health, to stress levels, creativity and cognitive (认知的) skills. Experts predict modern kids will have poorer health than their parents---and they say a lack of outside play is surely part of it; research suggests that kids do better academically in schools with a nature component(成份) and that play in nature develop leadership by the smartest, not by the toughest. Even a tiny outdoor experience can create wonder in a child. The three-year-old turning over his first rock realizes he is not alone in the world. A clump of trees on the roadside can be the whole universe in his eyes. We really need to value that more.

Kids are not to blame. They are overprotected and frightened. It is dangerous out there from time to time, but much stress from computers is replacing breaking an arm as a childhood process of passage.

Everyone, from developers, to schools and outdoorsy citizens, should help regain for our kids some of the freedom and joy of exploring, taking friendship in fields and woods that strengthen love, respect and need for landscape. As parents, we should devote some of our energies to taking our kids into nature. This could yet be our greatest cause.
