It's Mexico City's first pollution alert in 11 years.

These pigeons don backpacks and respond to Twitter requests to measure air quality over London.

Cars will be banned based on their license plate number, as China's authorities desperately try to curb record pollution levels in their capital city.

Like a certain Hobbit, the Environmental Protection Agency (EPA) wants to take a closer look at Smaug. Sorry, smog.

Move over Los Angeles, the city of Houston, Texas is now also officially on the "severe smog problem" list. The reclassification was requested by Governor Rick Perry last year and the Environmental Protection Agency (EPA) made the change last Thursday.
