The New York Times columnist Thomas Friedman is arguably one of the most influential voices in current American journalism. The Brandeis-and Oxford-schooled Friedman writes engagingly on such heavy-duty subjects as immigration law, oil addiction, and outsourcing. His examination of globalism, The World is Flat, has sold two million copies, and he is a solid favorite to win his fourth Pulitzer Prize for his latest best-seller, Hot, Flat, and Crowded. No ivory-tower thinker, he’s connecting with people in real life about the power of retooling the world’s economy by preserving the planet. "I’m getting big, big audiences. It tells me that people are really hungry to talk about this agenda." How would you summarize your new book The core of this book is that clean energy technology, clean water, all the clean sources of growth and sustenance are going to be the next great global industry. I know that for sure. What I don’t know is who’s going to lead that industry. Is it going to be America Is it going to be Russia, China, Japan, India All I know is ET, energy technology, is going to be the next great global industry, and if we want to maintain our standard of living we have to lead that industry. I want to make America the example of a country that grows rich, innovative, entrepreneurial, competitive, healthy, secure, and respected by taking the lead in inventing "clean and green" power, because I think many more people will follow us voluntarily than will ever reduce their emissions by compulsion of a treaty. If we build it, they will come. An op-ed in the Washington Post titled "Don’t Go There" argued that tourism is "nothing short of a planet-threatening plague". What’s your take In a world of increasingly rising, dangerous levels of CO2, and in a world of rising middle classes of India, China, Russia, Brazil — where more and more people will be able to do package tours like Americans or Europeans have done for years — there is no question that tourism has to put stress on ecosystems, on beaches, coral reefs, forests, ski slopes, and on ancient and cherished sites. But I just have a hard time saying, "Don’t go there." Those charged with protecting those ecosystems have to be that much more vigilant. The real point is pay attention wherever you are. Pay attention to your environment, your ecosystem, your carbon footprint, whether you’re at home or abroad. And if we all do that, then there’s no reason that travel will hurt things. If none of us do that or we only do that episodically, then even the smallest amount of travel will cause damage. A hundred tourists can spoil a great site or a lush valley as easily as 100,000 if you don’t have the right regulations. As parents, how can we inculcate in our children the idea of seeing and embracing the world When our girls were very young, my wife taught a class called World Class. She would pick a country or a city or a culture and do a little lesson about it for kids once a week. Other parents used to drop their kids off at our house to take the class. And so from a very young age, our girls were taught to be interested in and love different cultures, to go to museums, things of that nature. And that’s the most important thing you can do. You have to start them young. And another way to do that is to subscribe to magazines and newspapers. I got interested in news because my parents subscribed to Time magazine. Take your kids out to different dining experiences. Expose them to foreign movies. Make sure they study a foreign language in school. There are just myriad ways to get your kids to appreciate different cultures. Our girls are 23 and 20 now. They were both born in Jerusalem, so their very first trip was coming to America. What is the main idea of the passage
Are your Facebook friends more interesting than those you have in real life Has high-speed Internet made you impatient with slow-speed children Do you sometimes think about reaching for the lust-forward button, only to realize that life does not come with a remote control If you answered yes to any of those questions, exposure to technology may be slowly reshaping your personality. Some experts believe excessive use of the Internet, cellphones and other technologies can cause us to become more impatient, impulsive, forgetful and even more narcissistic. "More and more, life is resembling the chat room," says Dr.Elias Aboujaoude, director of the Impulse Control Disorders Clinic at Stanford. "We’re paying a price in terms of our cognitive life because of this virtual lifestyle." We do spend a lot of time with our devices, and some studies have suggested that excessive dependence on cellphones and the Internet is akin to an addiction. Websites like NetAddiction.com offer self-assessment tests to determine if technology has become a drug. Among the questions used to identify those at risk: Do you neglect housework to spend more time online Are you frequently checking your e-mail Do you often lose sleep because you log in late at night If you answered "often" or "always", technology may be taking a toll on you. In a study to be published in the journal Cyberpsychology, Behavior and Social Networking, researchers from the University of Melbourne in Australia subjected 173 college students to tests measuring risk for problematic Internet and gambling behaviors. About 5 percent of the students showed signs of gambling problems, but 10 percent of the students posted scores high enough to put them in the at-risk category for Internet "addiction". Technology use was clearly interfering with the students" daily lives, but it may be going too far to call it an addiction, says Nicki Dowling, a clinical psychologist who led the study. Ms.Dowling prefers to call it "Internet dependence". Typically, the concern about our dependence on technology is that it detracts from our time with family and friends in the real world. But psychologists have become intrigued by a more subtle and insidious effect of our online interactions. It may be that the immediacy of the Internet, the efficiency of the iPhone and the anonymity of the chat room change the core of who we are, issues that Dr.Aboujaoude explores in a book, Virtually You: The Internet and the Fracturing of the Self, to be released next year. Dr.Aboujaoude also asks whether the vast storage available in e-mail and on the Internet is preventing many of us from letting go, causing us to retain many old and unnecessary memories at the expense of making new ones. Everything is saved these days, he notes, from the meaningless e-mail sent after a work lunch to the angry online exchange with a spouse. "If you can’t forget because all this stuff is staring at you, what does that do to your ability to lay down new memories and remember things that you should be remembering" Dr.Aboujaoude said. "When you have 500 pictures from your vacation in your Flickr account, as opposed to five pictures that are really meaningful, does that change your ability to recall the moments that you really want to recall" There is also no easy way to conquer a dependence on technology. Nicholas Carr, author of the new book The Shallows: What the Internet Is Doing to Our Brains, says that social and family responsibilities, work and other pressures influence our use of technology. "The deeper a technology is woven into the patterns of everyday life, the less choice we have about whether and how we use that technology," Mr.Carr wrote in a recent blog post on the topic. Some experts suggest simply trying to curtail the amount of time you spend online. Set limits for how often you check e-mail or force yourself to leave your cellphone at home occasionally. The problem is similar to an eating disorder, says Dr.Kimberly Young, a professor at St.Bonaventure University in New York who has led research on the addictive nature of online technology. Technology, like food, is an essential part of daily life, and those suffering from disordered online behavior cannot give it up entirely and instead have to learn moderation and controlled use. She suggests therapy to determine the underlying issues that set off a person’s need to use the Internet "as a way of escape". The International Center for Media and the Public Agenda at the University of Maryland asked 200 students to retrain from using electronic media for a day. The reports from students after the study suggest that giving up technology cold turkey not only makes life logistically difficult, but also changes our ability to connect with others. "Texting and IM-ing my friends gives me a constant feeling of comfort," wrote one student. "When I did not have those two luxuries, I felt quite alone and secluded from my life. Although I go to a school with thousands of students, the fact that I was not able to communicate with anyone via technology was almost unbearable." What’s the solution to technology addiction, according to Dr.Kimberly Young
