COUNTING CARBONS

摘要

Not long ago, the rolling stones announced plans to ensure that an upcoming tour would not contribute to global warming: They had signed on to two forestry projects in Scotland, which would plant 2,800 trees, one for every 60 fans in the audience, and thus render the entire tour "carbon neutral." Better still, the Stones got a mobile phone company to pick up the extra cost of the saplings, about 20 cents a ticket. My first impulse was to laugh. Mick Jagger is a great performer, but he also personifies the jet-set lifestyle, blithely tripping from villa to penthouse on a gaudy 40-year-long plume of fossil-fuel exhaust. How could one tree possibly remove the carbon dioxide produced in getting thousands of rock-and-roll fans, let alone lights, amps, and the Stones themselves, to various stadiums on the tour? Does a pine seedling really work that hard? My second, less gratifying impulse was to wonder, What if they're right, or at least moving in the right direction? If you believe, along with almost every scientist who has studied the issue, that global warming poses a genuine threat to humanity, doesn't this suggest that we should be doing something about it?
