Beijing Blue Sky Days Hit 244

Beijing is like an athlete trying to get into shape by walking on a treadmill yet eating double cheeseburgers at the same time. Polluting factories have been moved or closed. But auto emissions are rising as the city adds up to 1,200 new cars and trucks every day. Dirty, coal-burning furnaces have been replaced, lowering the city’s sulfur dioxide emissions. But fine-particle pollution has been exacerbated by a staggering citywide construction binge that shows no signs of letting up.

China’s unsolved riddle is how to reconcile fast economic growth with environmental protection. But Beijing’s Olympic deadline means the city needs an immediate answer. The ruling Communist Party envisions the Games as a public relations showcase and is leaving no detail untended. Scientists are cross-breeding chrysanthemums to ensure that flowers bloom in August.
