People tend to think of computers as isolated machines, working away all by themselves. Some personal computers do without an outside link, like someone's secret cabin in the woods. But just as most of homes are tied to a community by streets, bus routes and electric lines, computers that exchange intelligence are part of a community local, national and even global network joined by telephone connections.
The computer network is a creation of the electric age, but it is based on old-fashioned trust. It cannot work without trust. A rogue (流氓) loose in a computer system called hacker is worse than a thief entering your house. He could go through anyone's electronic mail or add to, change or delete anything in the information stored in the computer's memory. He could even take control of the entire system by inserting his own instructions in the software that runs it. He could shut the computer down whenever he wished, and no one could stop him. Then he could program the computer to erase any sign of his ever having been there.
Hacking, our electronic-age term for computer break-in is more and more in the news, intelligent kids vandalizing(破坏)university records, even pranking (恶作剧) about in supposedly safeguarded systems. To those who understand how computer networks are increasingly regulating life in the late 20th century, these are not laughing matters. A potential for disaster is building: A dissatisfied former insurance-company employee wipes out information from some files; A student sends out a "virus", a secret and destructive command, over a national network. The virus copies itself at lightning speed, jamming the entire network thousands of academic, commercial and government computer systems. Such disastrous cases have already occurred. Now exists the possibility of terrorism by computer. Destroging a system responsible for air-traffic control at a busy airport, or knocking out the telephones of a major city, is a relatively easy way to spread panic. Yet neither business nor government has done enough to strengthen its defenses against attack. For one thing, such defenses are expensive; for another, they may interrupt communication, the main reason for using computers in the first place.

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. Fear-producing 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.
Each of us has a place in nature we go sometimes, even if it was torn down. We cannot be the last generation to have that place. At this rate, kids who miss the sense of wonder outdoors will not grow up to be protectors of natural landscapes. “If the decline in parks use continues across North America, who will defend parks against encroachment (蚕食)?” asks Richard Louv, author of Last Child in the Woods.
Without having a nature experience, kids, can turn out just fine, but they are missing out a huge enrichment of their lives. That applies 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 and that play in nature fosters (培养) 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 over-protected and frightened. It is dangerous out there from time to time, but repetitive stress from computers is replacing breaking an arm as a childhood rite(仪式)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 cement (增强) 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.
