It's no secret that China has a big pollution problem. However, far from getting better, all signs point to the fact that China's pollution problem is actually getting worse. And it's not just major cities like Shanghai and Beijing that are bearing the brunt of this pollution crisis.
Every major city in China is having air-quality problems. One of the worst is Nanjing. The other day, residents there suddenly found that the air around them had turned pink. Needless to say, they weren't too thrilled about it.
Officials rushed to figure out what was going on. They found that their city's air quality had suddenly jumped beyond the already terrible levels being experienced by residents in Beijing.
