单选题{{B}}Text 4{{/B}} The dot-com collapse may have been a disaster for Wall Street, but here in Silicon Valley, it was a blessing. It was the welcome end to an abnormal condition that very nearly destroyed the area in an overabundance of success. You see, the secret to the Valley's astounding multiple-decade boom is failure. Failure is what fuels and renews this place. Failure is the foundation for innovation. The valley's business ecology depends on failure the same way the tree-covered hills around us depend on fire--it wipes out the old growth and creates space for new life. The valley has always been in danger of drowning in the unwelcome waste products of success--too many people, too expensive houses, too much traffic, too little office space and too much money chasing too few startups. Failure is the safety valve, the destructive renewing force that frees up people, ideas and capital and recombines them, creating new revolutions. Consider how the Internet revolution came to be. After half a decade of start-up struggles, for example, hundreds of millions of Hollywood dollars were going up in smoke. It all seemed like a terrible waste, but no one noticed that the collapse left one very important byproduct, a community of laid-off C++ programmers who were now expert in multimedia design, and out on the street looking for the next big thing. These media geeks were the pioneer of the dot-com revolution. They were the Web's business pioneers, applying their newfound media sensibilities to create one little company after another. Most of these start-ups failed, but even in failure they advanced the new medium of cyberspace. A few geeks, like Silicon Graphics founder Jim Clark, succeeded and utterly changed our lives. In 1994 Clark was unemployed after leaving the company be founded, doggedly trying to develop a new interactive-TV concept. He approached Marc Andreessen, the co-developer of Mosaic, the first widely used Internet browser, in hope of persuading Andreessen to help him de-sign his new system. Instead, Andreessen opened Clark's eyes to the Web's potential. Clark promptly tossed his TV plans in the trash, and the two co-founded Netscape, the cornerstone of the consumer-Web revolution. Like the interactive-TV refugees and generations of innovators before them, the dot comers are already hatching new companies. Many are revisiting good ideas executed badly in the' 90s, while others are striking out into entirely new spaces. This happy chaos is certain to mature into a new order likely to upset an establishment, as it delivers life-changing wonders to the rest of us. But this is just the start, for revolutions give birth to revolutions. So let's hope for more of Silicon Valley's successful failures.

单选题THE ivory-billed woodpecker is not large, as birds go: It is about the size of a crow, but flashier, its claim to fame is that, though it had been thought extinct since 1944, a lone kayaker spotted it about two years ago, flying around among the cypress trees in the Cache River National Wildlife Refuge. And that sighting may prove the death-blow to a $319m irrigation project in the Arkansas corner of the Delta. The Grand Prairie Area Demonstration Project seemed, at first, a fine idea. The Grand Prairie is the fourth-largest rice-bowl in the world, with 363 000 acres under paddies. But it is running out of water, with farmers driving wells deeper and deeper into the underlying aquifer. The new project, dreamed up around a decade ago, would tap excess water from the White river when it floods and pumps it, at the rate of about one billion gallons a day, to storage tanks on around 1000 rice farms. Unfortunately, it would also divert water from the region's huge, swampy wildlife refuges, home to black bears and alligators and the pallid sturgeon. Tiny swamp towns like Clarendon and Brinkley, which are heavily black and almost destitute, rely on nature tourism for the little economic activity they have. In Brinkley, the barber offers an "ivorybill" haircut that makes you look like one. The project has some powerful local backers. They include Blanche Lincoln, the state's senior senator, who grew up on a rice farm in Helena, and Dale Bumpers, a former four-term senator and governor of Arkansas. Mr. Bumpers, long an icon of the environmental movement and prominent in the efforts to establish the refuges, now believes the water project is important for national security in food and trade, and that it will not damage the forests he has worked to protect. Opponents worry that the project, apart from its environmental risks, will overwhelm the innovative water conservation methods that rice-farmers are already using, and give the biggest water users an unfair advantage. They also object that it means using subsidised pumps to provide subsidised water for a crop that doesn't pay. Rice is one of the most heavily assisted crops in America; rice payments cost taxpayers almost $10 billion between 1995 and 2004, and rich farmers round Stuttgart in Arkansas County (an efficient and politically shrewd group) took in $21.2m in subsidies in 2004 alone.
