Beijing Welcomes World’s First Smog-Eating Tower

Beijingers enjoyed a rare breath of fresh air this week. The city’s smog levels fell to their lowest levels in recent years, as authorities scrambled to shut down factories and curb car use so that China’s Second World War victory military parade had a pollution-free backdrop.

But the blue skies will likely dissipate once the celebrations are over and cars go back on the roads, construction work restarts, and factories resume production.
