"With the Olympics due to start in less than three weeks, Beijing is cranking up antipollution measures by yanking cars off the roads, expanding mass transit and staggering work hours in a bid to meet its pledge of a "green" Olympics. Beijing has gone on a spending spree, relocating factories, seeding clouds, retiring old vehicles, planting millions of trees and halting building construction amid concerns that athletes and visitors could suffer breathing problems.
