ely - though by no means uniformly - glowingly positive.Science and technology would cure all the ills of humanity, leading to lives of fulfillment and opportunity for all. Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change.You might even be tempted to assume that humanity has little future to look forward to. But such gloominess is misplaced.The fossil record shows that many species have endured for millions of years - so why shouldn't we？ Take a broader look at our species' place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years .Look up Homo sapiens in the "Red List" of threatened species of the International Union for the Conversation of Nature (IUCN) ,and you will read: "Listed as Least Concern as the species is very widely distributed, adaptable, currently increasing, and there are no major threats resulting in an overall population decline." So what does our deep future hold？ A growing number of researchers and organisations are now thinking seriously about that question.For example, the Long Now Foundation has its flagship project a medical clock that is designed to still be marking time thousands of years hence . Perhaps willfully , it may be easier to think about such lengthy timescales than about themore immediate future.The potential evolution of today's technology, and its social consequences, is dazzlingly complicated, and it's perhaps best left to science fiction writers and futurologists to explore the many possibilities we can envisage.That's one reason why we have launched Arc, a new publication dedicated to the near future. But take a longer view and there is a surprising amount that we can say with considerable assurance.As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our descendants will find themselves. This long perspective makes the pessimistic view of our prospects seem more likely to be a passing fad.To be sure, the future is not all rosy.But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to improve the lot of those to come. {TS}Our vision of the future used to be inspired by

A. our desire for lives of fulfillment

B. our faith in science and technology

C. our awareness of potential risks

D. our belief in equal opportunity

e their emissions pledges transparent to outsiders and that the Obama administration isn't ready to follow Europe's lead in specifying how much money rich nations should contribute over the next decade to help poor countries respond to climate change.

gagement (CIRCLE) at Tufts University shows that today's youth vote in larger numbers than previous generations, and a 2008 study from the Center for American Progress adds that increasing numbers of young voters and activists support traditionally liberal causes. But there's no easy way to see what those figures mean in real life. During the presidential campaign, Barack Obama assembled a racially and ideologically diverse coalition with his message of hope and change; as the reality of life under a new administration settles in, some of those supporters might become disillusioned. As the nation moves further into the Obama presidency, will politically engaged young people continue to support the president and his agenda, or will they gradually drift away？

The writers of Generation O (short for Obama), a new Newsweek blog that seeks to chronicle the lives of a group of young Obama supporters, want to answer that question. For the next three months, Michelle Kremer and 11 other Obama supporters, ages 19 to 34, will blog about life across mainstream America, with one twist: by tying all of their ideas and experiences to the new president and his administration, the bloggers will try to start a conversation about what it means to be young and politically active in America today. Malena Amusa, a 24-year-old writer and dancer from St. Louis sees the project as a way to preserve history as it happens. Amusa, who is traveling to India this spring to finish a book, then to Senegal to teach English, has ongoing conversations with her friends about how the Obama presidency has changed their daily lives and hopes to put some of those ideas, along with her global perspective, into her posts. She's excited because, as she puts it, "I don't have to wait [until] 15 years from now" to make sense of the world.

Henry Flores, a political-science professor at St. Mary's University, credits this younger generation's political strength to their embrace of technology. "[The Internet] exposes them to more thinking," he says, "and groups that are like-minded in different parts of the country start to come together." That's exactly what the Generation O bloggers are hoping to do. The result could be a group of young people that, like their boomer (二战后生育高峰期出生的美国人) parents, grows up with a strong sense of purpose and sheds the image of apathy (冷漠) they've inherited from Generation X (60 年代后期和70 年代出生的美国人). It's no small challenge for a blog run by a group of ordinary—if ambitious—young people, but the members of Generation O are up to the task.
