Beijing's 'Airpocalypse' Spurs Pollution Controls, Public Pressure

In China's capital, they're calling it the "airpocalypse," with air pollution that's literally off the charts. The air has been classified as hazardous to human health for a fifth consecutive day, at its worst hitting pollution levels 25 times that considered safe in the U.S. The entire city is blanketed in a thick grey smog that smells of coal and stings the eyes, leading to official warnings to stay inside.
