Clearing the air

摘要

"Vote Republican: vote smogs". I doubt many bumper stickers carried that message during last year's US midterm elections. But choking air and kids dying of asthma may be what the Republican victory delivers. Republicans now control both houses of Congress and are all for throttling President Barack Obama's plans to lower the federal limit on ozone smog, announced by the US Environmental Protection Agency (EPA) right after the elections. They say it is unachievable, except at vast cost.
